[Dovecot] pop3+leave messages on server
by Papp Tamas 24 Jan '10

24 Jan '10

hi All, I have a srange problem. Before dovecot there was a courier imap and it worked just fine. The client(s) are the same then before, so I think, this is an server side problem. I have a user with Outlook and he uses pop3 and leaves messages on server. Sometimes the messages get downloaded again, when he starts the outlook. Not all, but 7-9 hours back. uidl format is like it's suggested: pop3_uidl_format = %08Xu%08Xv Any idea, what's wrong and what I can do? Thank you very much, tamas

[Dovecot] strange behaviour with seen/unseen messages in virtual folders.
by Matthias Rieber 24 Jan '10

24 Jan '10

Hi, I've a virtual folder that contains unseen messages. When I mark the message and expunge the folder, the message should disappear. This works as expected in alpine. Alpine uses the following commands: 06000010 STORE 1 +Flags (\SEEN) 06000020 EXPUNGE Using roundcube mail, the message wont disappear, when I perform the same steps. RoundCube Mails sends: flg UID STORE 445 +FLAGS (\Seen) exp1 EXPUNGE But the message doesn't dissapear. But I can expunge it with alpine, as long as the folder contains one message. If it contains more messages, some or even all messages won't disappear. When I mark them as unseen/seen in alpine, I can expunge them with alpine. The expunge command send by roundcube mail never expunges any seen message in the unseen folder. Whether it was flagged as seen by alpine nor roundcube mail. kind regards, matthias

[Dovecot] Need simplest method for providing alternate mail location
by Stewart Dean 24 Jan '10

24 Jan '10

I am looking to migrate my DC V1.2 from mbox to maildir format....and want to do this in stages, user group by user group rather than in one horrendous fell swoop....since I'd rather fell things didn't happen. Since I'm running sendmail/procmail, I can change the ~/.procmailrc to change the writing of the INBOX, but the IMAP mail location access info is knottier when one wants to do things a bit at a time. Setting aside for now the matter of converting existing folders, I will be moving: = from a mbox setup with the INBOX in /var/spool/mail/<userid> and the folders in ~/mail = to both in ~/Maildir (unless someone has better ideas) It seems that one could: 1) Change the namespaces in the client...but this is not feasible, because it would means going out to all my 4000+ users desktop and modifying them. 2) Having some sort of db to tell DC it a mail_userdb extra field and override the mail_location in dovecot.conf 3) Perhaps waiting for DC v2.0 which will have this architected in. A) Is there any sense the v2.0 will be coming Real Soon Now and will fulfill #3? B) What's the simplest way to implement #2? I would really rather not install MySQL on my mail server and have all the overhead of installing and managing it when all I need it for is a temporary resource to tell DC where things are until the switchover is complete and Maildir is the default. Is it feasible to do this with an additional flat file in the /etc/passwd mode with some extra fields tacked on that is *only* used for mail location info? Or some other and simple way?

[Dovecot] SpamAssassin and i;ascii-numeric comparator
by Julian Cowley 24 Jan '10

24 Jan '10

Hi Stephan, I noticed that you changed i;ascii-numeric comparator recently (<http://hg.rename-it.nl/dovecot-1.2-sieve/rev/17fb38aee85f>) to correct a small bug. I have an interest in this because I use the comparator to check for SpamAssassin scores. Before the fix, this was all that was necessary to check for scores above a certain value: header :value "ge" :comparator "i;ascii-numeric" "X-Spam-Score" "5" Since SpamAssassin includes negative scores and the i;ascii-numeric comparator doesn't recognize negative numbers, all negative scores are actually treated as positive infinity after the fix. Of course, this means mail which has a negative score then gets counted as spam. Now an additional test is necessary, something like this: allof(not header :matches "X-Spam-Score" "-*", header :value "ge" :comparator "i;ascii-numeric" "X-Spam-Score" "5") I thought I'd mention this because other people may get affected by this once 0.1.15 comes out. Here is a patch that makes further tests for the comparator between numeric and non-numeric values. Hope you can use it. -=- julian

[Dovecot] how to create maildir on local mail delivery
by Sebastian Logar 24 Jan '10

24 Jan '10

Hi! I am using Dovecot 1.0.10 with LDA/postfix option reading user data from ldap, but the problem would be nonexistent maildir. Connection with ldap should be fine since reading proper maildir folder. Is it possible to auto creating maildir folders even on received mail since the you can auto create when user login with mail_executable scripts as it's seen from configuration I am doing for pop3 and imap.

[Dovecot] feature question: local delivery from SMTP
by Phil Howard 23 Jan '10

Does Dovecot really need a separate MTA for inbound mail? Or can it receive SMTP directly if there is no forwarding to do? What about spam/virus filtering in that case? -- Phil Howard KA9WGN - ka9wgn(a)gmail.com

[Dovecot] Mail process plans: multiple connections in a process + idle processes
by Timo Sirainen 23 Jan '10

23 Jan '10

Maybe for v2.1: imap and pop3 processes can currently handle multiple connections, but they're assigned pretty much randomly to processes. It would be better if it was possible to: a) Require that a process handles only a specific user's connections b) Require that a process handles only a specific UNIX UID's connections (e.g. if each domain has a separate UID) c) Prefer to put user's connections to same process, but don't require it. To do this, there needs to be a process between imap/pop3-login and imap/pop3. Let's call it imap/pop3-tracker process (or aggregator? or any suggestions?). This process accepts all connections coming from login processes when they've finished authenticating a connection. Internally it figures out if the connection should go to a new or an existing process. It keeps track of username -> { mail_process[], cookie (see idle processes below) } mail_process -> { unix_socket_fd, connection_count } So there's a connection to each mail process. This connection is used to send connection fds for the process to handle. It's also used to receive notifications when a connection is closed. The mail process sockets could also be used to communicate to a specific process. For example doveadm could use this in future to ask what a specific user or process is currently doing, by connecting to imap-tracker, which forwards the request to wanted process(es). The above isn't really anything new, just a more specific plan about what I had been thinking for a long time. A new and more interesting idea is to gather IDLEing imap connections under a few imap-idle processes: When a connection has been IDLEing for a few minutes (or something), and there's no special state in the connection (e.g. CONTEXT=SEARCH searches), the connection could be moved to a separate imap-idle process that simply waits for something to happen. When something does happen, it'll move the connection back to imap process, which restores state and continues. The idea would be to reduce the number of idling imap processes that are wasting memory. The state that needs to be saved and restored is: - selected mailbox name, GUID, UIDVALIDITY (for reliably selecting back the original mailbox, or reliably fail if it's gone) - flag: mailbox is EXAMINEd, not SELECTed - highest seen modseq - UIDs of \Recent messages - SEARCHRES extension: last saved SEARCH result - List of keywords that had been advertised in FLAGS/PERMANENTFLAGS reply to client. Or probably MD5 sum of it would be enough. If MD5 had changed, the list would be re-sent to client. - connection fd - paths that are being monitored with [id]notify/kqueue Connection is moved back when a) new command is received from connection fd, b) one of the monitored files changes. The connections are moved back via imap-tracker process, by sending the saved state along the request. For security there's a per-user security cookie (128 bits of randomness), which is sent to imap processes, and when restoring connection from imap-idle, the request must provide the correct cookie or imap-tracker fails the login. (Normally new post-login imap/pop3 connections can't be created without having authenticated first via dovecot-auth. They verify it.) So when connection comes back, imap process opens the mailbox based on saved information. If this fails for some reason (e.g. mailbox deleted), client gets disconnected. Next Dovecot gets a list of changes to mailbox since the saved modseq, and based on that sends the missing FETCH, EXPUNGE, EXISTS and RECENT events. Again if it somehow fails, the client gets disconnected. At least initially this would only be done for connections that are running IDLE command, because non-IDLE connections are a lot more difficult to restore to their original state. This is mainly because if a message gets expunged, it's still visible to the connection until it issues a command that allows sending EXPUNGE event. To handle that, there would have to be code that allows building a view of mailbox where there are some expunged messages. Also it can be difficult to find out the expunged messages' flags, unless they're also part of the saved state.

[Dovecot] format of file dict
by Frank Cusack 22 Jan '10

22 Jan '10

For shared (between users) mailboxes, I am using a file dict. plugin { acl_shared_dict = file:/etc/dovecot/acl_shared_dict/shared.db } What is the format of this file? I would like to manage it directly rather than have SETACL update it. I see lines which describe a sharing entry (the format of those looks obvious) but also lines with just a '1'. Do I just need to separate entries by lines with just '1' in them? -frank

[Dovecot] Thinderbird+delete+move to Trash folder
by Papp Tamás 22 Jan '10

22 Jan '10

hi All, I have a problem, which makes me headache. I can't find out, what is the problem. I have a mail szerver, which works just fine as expected, TB move messages to trash folder after I delete it, and they are moved. I have an other server. If I delete a message, it doesn't move to the Trash folder. As deleted_to_trash plugin is installed, if I only mark messages as deleted, they are moved to thee Trash folder and also with Outlook works well. It's like when a messages is deleted from TB, the message get moved to the Trash folder, and it's expunged(?) at the same time. Is it possible? Could you help me? The system is Ubuntu 9.04 with docecot 1.2.5-0~auto+0 from http://xi.rename-it.nl/debian/, but builded by myself for x86_64. Thank you, tamas

[Dovecot] Modifying the underlying maildir externally (webmail, replication)
by Attila Nagy 22 Jan '10

22 Jan '10

Hello, I have a setup where there are multiple maildir users, one of them being the pop/imap server itself, the others are for example a maildir capable webmail and message replication. I would like to evaluate Dovecot, but I wonder how would its binary indexes and logs fit into this picture. After running through http://wiki.dovecot.org/IndexFiles I'm not sure how well would Dovecot work with other programs modifying the maildirs (adding, deleting, moving messages, folders etc). The "Main index" section says "The index file is synchronized against mailbox only if the syncing information changes.", where syncing information consists or cur and new directories' timestamps. Does that mean I am safe there? The cache file is hopefully just a cache, so it won't contain information from messages which are inserted or moved by an external program, and I assume Dovecot fetches the message lists and other information from the main index, which seems to be OK. The transaction log is for the main index, so if the latter is OK, the former should be OK too. http://wiki.dovecot.org/MailboxFormat/Maildir talks about MUAs and there nothing scary can be found, except for some temporary conditions, where the changes won't propagate to Dovecot in real time, but it's OK. Are the above right, and can Dovecot use its indexes and caches safely with others using the same maildirs? Thanks,

[Dovecot] Files Moving From /New to /Cur
by Tony Rutherford 22 Jan '10

22 Jan '10

Using Dovecot 1.2-9 with Maildir and layout=FS. We have our own delivery pushing messages to the /new and then /cur folder eventually. When I have an IMAP client attached, there is apparently some sort of race going on. I believe that Dovecot is moving files from /new to /cur (and renaming them) before our own delivery gets the job done. This is causing a problem for us. Is there a way to disable this in Dovecot? I have the LDA section commented out of the config file..so I don't think that's in play. Bottom line is that I don't want Dovecot to move any files around whether an IMAP client is attached or not (except for handling the IMAP COPY/APPEND). Regards, Tony

Just wanted to share the bad news: https://bugzilla.mozilla.org/show_bug.cgi?id=541337 It seems that Dovecot is really showing the Mozilla Thunderbird team how to read and use an RFC ;-) -- Christian Rohmann Content Delivery Server u.

[Dovecot] Conditionally use a sieve script with deliver?
by Kārlis Repsons 22 Jan '10

22 Jan '10

I found a post in this list [0], which says sieve scripts can be used to deliver mail as read. However, can it be done somehow conditionally, I mean, with a direct or indirect switch for deliver? For a nonexistent example, it would be simply < | deliver -m path/to/maildir -r > or maybe an environment variable could be exported to deliver sieve and checked there? (Still not sure if sieve can replace maildrop in my case, however, using it with dovecot creates various problems with interoperability; but perhaps I can just add those imap4flags like "\\seen" myself to the message with maildrop and avoid mess with sieve at all?)

[Dovecot] IDLE timing issue - dovecot or fetchmail issue?
by Matt Doran 22 Jan '10

22 Jan '10

Hi guys, Thanks for the great product. We've used dovecot for ages as our internal mail server and it works great! I've recently started using fetchmail 6.3.9 (with IDLE enabled) to download mail from our ISP (Pair networks). The ISP is running Dovecot 1.1.16. I am unable to get the info about the dovecot config at this time. The IDLE support in fetchmail allows us to deliver mail near instantaneously without the need to poll (which is what we did previously using POP3). However I've noticed an issue where if 2 mails are delivered in quick succession fetchmail will only download the first email, and the second will not download. If I then send in another test email this triggers the download of 2 emails (the original that wasn't downloaded and the test email). Now I'm wondering whether the issue lies with Dovecot (e.g. a timing issue), or is it fetchmail that isn't implementing the IDLE/download properly. I've attached the output of a fetchmail session showing this problem in action (I've added some annotations to this file starting with >>>>>). The sequence of events are: * Start fetchmail with IDLE enabled * Send 2 emails in quick succession. * Dovecot notifies of the new message * Fetchmail downloads the message * Fetchmail initiates a new IDLE * Then nothing more is delivered. :( * I then send another email, which triggers the 2 to download. I don't know enough about IMAP to understand whether the problem lies with Dovecot or Fetchmail. Hopefully an IMAP expert will be able to see from the attached IMAP session.

[Dovecot] IMAP only for some users or via webmail
by Federico Tomasczik 22 Jan '10

22 Jan '10

Hello! First, sorry for my English... I'm a newbie with Dovecot and I have some questions, I'm testing Dovecot 1.1.11 in a virtual machine. I wish in the future, migrate this to a real server. Ok, but i need this: 1) A group of users can use IMAP or POP3. 2) The others, only can use POP3. But, this users can use IMAP only with a webmail (the webmail is in the same server that Dovecot) It is possible? How? Thanks! Federico Ch. Tomasczik

[Dovecot] nologin in auth proto version 1.1
by Kirill Miazine 21 Jan '10

21 Jan '10

I notice that the nologin parameter for the AUTH command is gone in version 1.1 of Dovecot Authentication Protocol. nologin was added in 1.1, so that authentication client could indicate that there will be no subsequent master requests to retrieve user info. Could we have nologin back please? Kirill

[Dovecot] Fastest restart of dovecot after upgrade: HOW?:
by Ralf Hildebrandt 21 Jan '10

21 Jan '10

I'm running dovecot under runit: #!/bin/sh echo '/var/core/%p' > /proc/sys/kernel/core_pattern ulimit -n 8096 ulimit -c unlimited exec /usr/local/sbin/dovecot -F (that way, together with incron, I can automatically generate the coredumps I'm posting all the time) If I apply a patch and recompile, what is the fastest way of restarting dovecot? Which part of the process structure can be killed and takes all it's children with it? ├─runsvdir─┬─runsv───ntpd │ ├─runsv─┬─dovecot─┬─2*[dovecot-auth] │ │ │ ├─1203*[imap] │ │ │ ├─64*[imap-login] │ │ │ ├─64*[managesieve-log] │ │ │ └─64*[pop3-login] │ │ └─svlogd killall dovecot? Is that guaranteed to wipe out ALL child processes as well?

[Dovecot] Maildir and IMAP keywords
by Per-Erik Persson 21 Jan '10

21 Jan '10

When a user in thunderbird toggles some flags like junk, spam or something similar dovecot appends these flags form a-z to the end of the file in maildir. I have another application that also access the maildirs which gets really upset with these flags and ignore those emails. Are there any other way for dovecot to store these flags to make it compatible with other softwares?

[Dovecot] Migration from Courier to dovecot
by Werner Detter 21 Jan '10

21 Jan '10

hi list, I've just registered to the list, so please be tolerant ;) I'm currently in the process of planning the migration from courier to dovecot as POP/IMAP-Server. I'm migration from Courier 0.58 (Debian-Etch-packages) to Dovecot 1.1.13 (Debian Lenny Backport). The conversion of the Mailbox from Courier to Dovecot will be done with "courier-dovecot-migrate.pl"-script[1], which works fine. However after running "courier-dovecot-migrate.pl" the Courier-Files still remain in the Maildir. Can i just delete those Courier-specific-files or does dovecot need them somehow (do you normally get rid of these after conversion)? It's about these files: courierimapacl courierimapsubscribed courierimapuiddb courierpop3dsizelist And those directories: courierimaphieracl courierimaphieracl Can i simply delete those with "find" ? Furthermore: is it possible to convert back from Dovecot-Format to Courier-Format? Thanks in advance, Werner [1] http://www.dovecot.org/tools/courier-dovecot-migrate.pl

[Dovecot] MUA notifications on new mail in a new folder?
by Kārlis Repsons 20 Jan '10

20 Jan '10

If deliver gets run with a non-root userid like this: < | deliver -m path/to/NEWmaildir >, I wonder, is a connected IMAP MUA automatically notified, that the new message has arrived in the new folder? As I see from some experiments with Thunderbird, it has no problems with immediate notifications of new mail in previously existing folders, however, it has problems with the case of new folder.

[Dovecot] outlook 2007 can't see public folders more than 1 deep
by Frank Cusack 20 Jan '10

20 Jan '10

dovecot-1.2.9 I have a public folder using ACLs to determine who can access it. namespace public { separator = / prefix = shared/ location = maildir:/var/maildir/shared subscriptions = no } Outlook 2007 can't see any folders except at the top level. It can create them just fine, but can't see them after quit and restart. For example, I can create the folder shared/foo/bar but on restart outlook only sees foo as a folder without subfolders (no + to expand it) and doesn't see bar anymore. In fact I can delete the folder foo in outlook and then BOTH .foo and .foo.bar directories are removed on the server. When you click on foo, the error message in the mail pane is "Cannot display the folder. The folder 'foo' cannot contain items. This is most likely a limitation of your IMAP server. In order to create a folder that can contain items, be sure not to append '/' to its name as you create it." -frank

[Dovecot] md5_verify(...): Not a valid MD5-CRYPT or PLAIN-MD5 password
by BaQs 20 Jan '10

20 Jan '10

'afternoon list! I use mysql as userdb, which contains two type of password schemes: DES and MD5-CRYPT. I read there : http://wiki.dovecot.org/Authentication/PasswordSchemes that both are supported by dovecot. Unfortunately, dovecot keeps saying: Not a valid MD5-CRYPT or PLAIN-MD5 password when looking for a user with DES encrypted password. Is dovecot able to recognize password scheme, or do I have to do something else ? I can't add {DES} to DES passwords, as this database is used with many other softwares. Thanks a lot for your help Pierre

[Dovecot] Two different issues with dovecot 1.1.13
by Stuart Rowan 20 Jan '10

20 Jan '10

Hi Timo, I'm using Debian backports.org dovecot-imapd, 1:1.1.13-2~bpo50+1. I've got two different issues, a reoccurring, seemingly harmless one about "Corrupted index cache file" (boring.txt) and one that went bonkers over the least few days (bt.txt) causing much spamming of the logs. I've made bt.txt stop happening by just rm'ing dovecot.index* : find Maildir/ -type f -name 'dovecot.index*' -print0 | xargs -0r rm ... which I realise may not be the most helpful thing to have done from your point of view. Anyway I just wanted to let you know about both of these. If one or both are already known about or already fixed by a later version of Dovecot, great and sorry for the noise! If not, and you want any more information etc., let me know. Many thanks, Stu. dovecot: 2009-07-28 10:23:16 Error: IMAP(strr): Corrupted index cache file /home/local/strr/Maildir/dovecot.index.cache: record continues outside its allocated size dovecot: 2009-07-28 10:23:56 Error: IMAP(strr): Corrupted index cache file /home/local/strr/Maildir/dovecot.index.cache: record continues outside its allocated size dovecot: 2009-07-28 08:05:54 Panic: IMAP(strr): file index-mail-headers.c: line 77 (index_mail_parse_header_finish): assertion failed: ((match[match_idx] & HEADER_MAT CH_FLAG_FOUND) == 0) dovecot: 2009-07-28 08:05:54 Error: IMAP(strr): Raw backtrace: imap [0x48dbf2] -> imap [0x48dc73] -> imap [0x48d346] -> imap(index_mail_parse_header+0x617) [0x4545f7] -> imap [0x483284] -> imap [0x483478] -> imap(i_stream_read+0x2c) [0x491d7c] -> imap(i_stream_read_data+0x46) [0x491f16] -> imap(message_get_body_size+0x108) [0x4885 a8] -> imap [0x4226c3] -> imap(imap_fetch+0x162) [0x420852] -> imap(cmd_fetch+0x23c) [0x41a27c] -> imap [0x41e46c] -> imap [0x41e51d] -> imap [0x41eb25] -> imap(clien t_input+0x63) [0x41efd3] -> imap(io_loop_handler_run+0xcb) [0x49515b] -> imap(io_loop_run+0x18) [0x4945c8] -> imap(main+0x3da) [0x426bea] -> /lib/libc.so.6(__libc_sta rt_main+0xe6) [0x7f0e851941a6] -> imap [0x418859] dovecot: 2009-07-28 08:05:54 Error: child 20007 (imap) killed with signal 6 (core dumps disabled) dovecot: 2009-07-28 08:05:56 Panic: IMAP(strr): file index-mail-headers.c: line 77 (index_mail_parse_header_finish): assertion failed: ((match[match_idx] & HEADER_MAT CH_FLAG_FOUND) == 0) dovecot: 2009-07-28 08:05:56 Error: IMAP(strr): Raw backtrace: imap [0x48dbf2] -> imap [0x48dc73] -> imap [0x48d346] -> imap(index_mail_parse_header+0x617) [0x4545f7] -> imap [0x483284] -> imap [0x483478] -> imap(i_stream_read+0x2c) [0x491d7c] -> imap(i_stream_read_data+0x46) [0x491f16] -> imap(message_get_body_size+0x108) [0x4885 a8] -> imap [0x4226c3] -> imap(imap_fetch+0x162) [0x420852] -> imap(cmd_fetch+0x23c) [0x41a27c] -> imap [0x41e46c] -> imap [0x41e51d] -> imap [0x41eb25] -> imap(clien t_input+0x63) [0x41efd3] -> imap(io_loop_handler_run+0xcb) [0x49515b] -> imap(io_loop_run+0x18) [0x4945c8] -> imap(main+0x3da) [0x426bea] -> /lib/libc.so.6(__libc_sta rt_main+0xe6) [0x7f2edf08b1a6] -> imap [0x418859] dovecot: 2009-07-28 08:05:56 Error: child 20984 (imap) killed with signal 6 (core dumps disabled)

[Dovecot] Autobuilder packages for Debian stable/i386 now available
by Stephan Bosch 20 Jan '10

20 Jan '10

Hi, A few days back I started the first automated slave builder that produces bleeding edge Debian stable packages for Dovecot v1.2 and v2.0. It uses the source packages already provided by the automated master repository (which builds binary packages for Debian testing), so that the version numbers and content are equal throughout all Debian releases. The repository is available as follows: deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-1.2 main Or, for Dovecot v2.0: deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.0 main Read this for more information: http://wiki.dovecot.org/PrebuiltBinaries#Automatically_Built_Packages I hope to add amd64 binary support soon. Regards, Stephan.

Re: [Dovecot] Oracle SQL driver

Your commit appears to ignore errors and just commit everything > that goes through? Also since nothing is actually sent before commit(), > your rollback() shouldn't need to send ROLLBACK. You right. I've corrected the transaction handling mechanism. The only thing I couldn't understand: why rollback() shouldn't need to make real ROLLBACK? In case when whole transaction was failed succeded statements will remain uncommited. Then they will be commited later on next successful transaction. May be ROLLBACK is still needed? > The "VARCHAR sqltext[2048]" seems like an unnecessary restriction on the > query length. Wasn't there a way to do this without the limit? Or in AFAIK there is no possibility to use C types in PREPARE statement. Also Oracle cannot handle unsized VARCHARs. I've increased VARCHAR size to 65535. > test_connection() seems unnecessary. Right you are. > Couldn't driver_oracle_generate_name() be simply: > static unsigned int counter = 0; > return i_strdup_printf("ORACONN_%x", ++counter); =) Right. > driver_oracle_escape_string() really should be escaping the string. I made this function to replace single quote in string with two single quotes. IMHO this should be enough. How do you think? > Kind of annoying that each query needs a cursor, even though nearly all > queries are expected to return only a single row, but I guess that can't > be helped with the current API.. Yes. There are no other ways to work with untyped statements in OCI. But Oracle claims that all these statements shouldn't produce significant performance impact. The new version attached.

Re: [Dovecot] How can I configure dovecot as gmail imap proxy
by Supratik Goswami 20 Jan '10

20 Jan '10

Here the proxy server should authenticate the user. If the user is in the list of authenticated users then dovecot will allow to connect to imap.gmail.com. Consider a scenario where a client tries to read his mailbox from imap.gmail.com:993. Client executes the command "mutt -f imaps://imap.gmail.com", the request is first authenticated at the proxy server. If the request is coming from a valid user, dovecot will allow to connect to imap.gmail.com and fetch mails for that user. Can you please help me with the steps to configure the server. Warm Regards Supratik

[Dovecot] LDA and POP3/IMAP user_query
by Michael 20 Jan '10

20 Jan '10

How do I get IMAP+POP3 vs. LDA to use different user_query statements? The problem is that the input fields are different. IMAP/POP3 is an email address LDA is a username I have written a long statement to try and cater for both however it still only works 99% of the time, and the remaining 1% fails. The 1% that fails sees the mail being delivered to the wrong mbox. In this particular case the same client owned both mboxes so it was ok, but if this had not been the case things could have gotten real embarrassing. Think of the following: abcwidgets(a)theirdomain.tld mailuser1 mailuser1(a)adomain.tld mailuser2 Now when using the Postfix LDA, email for each address is properly delivered to the specified mbox, however in this case because their is a matching name for the mbox and the email address lefthand content, the compound SQL query returns both results and the LDA will use the first one, which in this case was the wrong one. This is the query used: user_query = \ SELECT mailboxes.username AS user, mailboxes.uid, mailboxes.gid, \ concat('*:storage=',mailquota,'M') AS quota_rule \ FROM mailboxes JOIN accounts ON accounts.username = mailboxes.username \ WHERE ((mailboxes.username = '%n' AND accounts.active='1') || \ (mailboxes.email = '%u' AND mailboxes.active='1' AND accounts.active='1') || \ (mailboxes.email = CONCAT('@','%d') AND mailboxes.active='1' \ AND (SELECT COUNT(email) FROM mailboxes WHERE email='%u') = '0')) which additionally caters for the few catch alls our users have. I think this is a massive oversight in the design of Dovecot to use one query to for 2 separate and distinct processes, that both use different parameters. From what I can tell it seems to assume that a mail system will always use username@domain addresses, and never anything more arbitrary. Has anyone found a way around this? Michael

[Dovecot] shared namespaces with common prefix prefix
by Frank Cusack 19 Jan '10

19 Jan '10

Can shared/public namespaces' prefixes have a common prefix? :) namespace public { separator = / prefix = zz/shared/ location = maildir:/var/maildir/shared:INDEX=/var/maildir/%n/shared subscriptions = no } # to share other employees mailboxes (term'd or admin access) namespace shared { separator = / prefix = zz/shared/%%u/ location = maildir:/var/maildir/%%n:INDEX=/var/maildir/users/%%u subscriptions = no list = children } Since I added the shared namespace, I can no longer access the public namespace. The folders show up but then trying to access one gets the error that the mailbox doesn't exist. If they can't have a common part of the prefix, is that an IMAP limitation or could dovecot conceivably handle it? -frank

[Dovecot] Log the virtual email address and not the local account - dovecot 1.2.2 w/ MySQL
by Bill 19 Jan '10

19 Jan '10

I recently started using dovecot and have it working well but I have one item I haven't been able to find an answer for. I am using MySQL with Dovecot for authentication with my virtual email customers. When the user logs in and checks email a log entry is recorded. Instead of the email address (bob(a)bob.net) being logged it records the local account (vemail101) in the POP3 log. How can I get dovecot to reflect the email address that the customer logged in with instead of the local account? Thx, Bill

[Dovecot] fts squat non-english search for 2 words
by vuser1＠test123.ru 19 Jan '10

19 Jan '10

Hello, It looks I encoutered a bug or misconfiguration. fts_squat search for subject and body works excellent for English mails. For non-English (in particular, Russian) it works only when query consists of 1 word. Phrases - 2 and more words - always returns nothing. Example: search for "planet" ("планета") returns results, search for "Earth" ("Земля") also returns results, but "planet Earth" ("планета Земля") returns nothing. But there are emails having exact phrase "planet Earth". This problem occurs only for non-English queries, both for search in subject and in email body. I tried web-mail Horde 3.2 and Thunderbird. I turned fts plugin off and it correctly finds phrases with 2 and more russian words! So problem is squat. Is it a bug or known config issue?

[Dovecot] virtual namespace question
by Josephus 19 Jan '10

19 Jan '10

Hi, I'm wondering if it is possible to create a virtual namespace on a prefix other than "virtual/". My goal is to mix IMAP folders with virtual folders on the same folder level (prefix = ""). mail_location = maildir:/data/mail/%d/%u/ # Virtual namespace private { prefix = separator = / location = virtual:/data/mail/%d/%u/virtual } # Default namespace private { separator = / prefix = inbox = yes } With this configuration the folders show up on the same level, but I'm unable to subscribe to them. When I change the prefix back to "virtual/" it works, but folders are still gruoped under "virtual". Funny thing is, when I use a prefix something like "vfolder/", the root folder is no longer greyed out in my MUA (TB3), and I get a "Mailbox doesn't exist: vfolder" error msg if I click on it. BR, Jos

[Dovecot] Best way of dealing with Case-Sensitive Issues in Dovecot
by Mario Antonio 19 Jan '10

19 Jan '10

In order to deal with case-sensitive issues, I am thinking to use the variable %L (adding it to my current configs --as suggested before by other users in this list) in the configuration files in this way: In Dovecot.conf: mail_location = maildir:/vmail/%Ld/%Ln/Maildir:INDEX=/indexes/%Ld/%Ln auth default: username_format: %Lu passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: static args: uid=5000 gid=5000 home=/vmail/%Ld/%Ln allow_all_users=yes In dovecot-sql.conf: password_query = select concat(virtual_users.user, '@', virtual_domains.name) AS user, virtual_users.password as password \ from virtual_users LEFT JOIN virtual_domains ON virtual_users.domain_id=virtual_domains.id \ where virtual_users.user='%Ln' and virtual_domains.name='%Ld' and virtual_users.status = 1 and virtual_domains.status = 1; user_query = SELECT 5000 AS uid,5000 AS gid,'/vmail/%Ld/%Ln' as home, \ concat('*:storage= ', virtual_users.quota_kb) AS quota_rule \ from virtual_users LEFT JOIN virtual_domains ON virtual_users.domain_id=virtual_domains.id \ where virtual_users.user='%Ln' and virtual_domains.name='%Ld' Is this the correct way of assuring lowercase use all over the place? Can I use the variable %L in where sql statements? Regards, Mario Antonio

[Dovecot] expire plugin doesn't find mail location
by Roland Rosenfeld 19 Jan '10

19 Jan '10

Hi! After searching for hours now, I give up and have to ask here. I try to use the expire plugin but it always tries to expire my mails instead of the mails of the user. I read about the "Mail location setting problem (v1.1-v1.2) and configured a "mail" extra field in the userdb, but that doesn't have the effect I want. I have not idea, what I could try out more, so I ask here. My setup is the following: # 1.2.9: /usr/local/dovecot/etc/dovecot.conf # OS: SunOS 5.10 sun4v zfs syslog_facility: local6 protocols: imap pop3 managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): *:2000, *:4190 ssl: no disable_plaintext_auth: no login_dir: /usr/local/dovecot/var/run/dovecot/login login_executable(default): /usr/local/dovecot/libexec/dovecot/imap-login login_executable(imap): /usr/local/dovecot/libexec/dovecot/imap-login login_executable(pop3): /usr/local/dovecot/libexec/dovecot/pop3-login login_executable(managesieve): /usr/local/dovecot/libexec/dovecot/managesieve-login mail_uid: 2001 mail_gid: 2001 mail_location: maildir:/var/mailstore/%2Mn/%n/mail mail_debug: yes mail_executable(default): /usr/local/dovecot/libexec/dovecot/imap mail_executable(imap): /usr/local/dovecot/libexec/dovecot/imap mail_executable(pop3): /usr/local/dovecot/libexec/dovecot/pop3 mail_executable(managesieve): /usr/local/dovecot/libexec/dovecot/managesieve mail_plugins(default): quota imap_quota expire mail_plugins(imap): quota imap_quota expire mail_plugins(pop3): quota expire mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/dovecot/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/dovecot/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/dovecot/lib/dovecot/pop3 mail_plugin_dir(managesieve): /usr/local/dovecot/lib/dovecot/managesieve pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %v.%u pop3_uidl_format(managesieve): %08Xu%08Xv namespace: type: private separator: / inbox: yes list: yes subscriptions: yes lda: postmaster_address: postmaster(a)netcologne.de hostname: mailstore20.netcologne.de mail_plugins: sieve quota expire auth_socket_path: /usr/local/dovecot/var/run/dovecot/auth-master auth default: master_user_separator: * verbose: yes debug: yes passdb: driver: passwd-file args: /usr/local/dovecot/etc/passwd.master pass: yes master: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /usr/local/dovecot/var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir expire: INBOX 60 Spam 60 Papierkorb 60 Trash 1 expire_dict: proxy::expire dict: expire: mysql:/usr/local/dovecot/etc/dovecot-dict-expire.conf With the following dovecot-sql.conf: driver = mysql connect = host=localhost dbname=cyrus user=cyrus password=XXXX default_pass_scheme = CRYPT password_query = \ SELECT username, password, concat('*:storage=', quota) AS userdb_quota_rule, '/var/mailstore/%2Mn/%n' as userdb_home, 'maildir:/var/mailstore/%2Mn/%n/mail' as userdb_mail \ FROM passwd WHERE username='%n' user_query = \ SELECT concat('*:storage=', quota) AS quota_rule, '/var/mailstore/%2Mn/%n' as home, 'maildir:/var/mailstore/%2Mn/%n/mail' as mail \ FROM passwd WHERE username='%n' And this is dovecot-dict-expire.conf: connect = host=localhost dbname=dovecot user=dovecot password=XXXXXX map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } In user test's Trash folder there are mails that are older than 1 day and in dovecot.expires there is +----------+---------+--------------+ | username | mailbox | expire_stamp | +----------+---------+--------------+ | test | Trash | 1262779049 | +----------+---------+--------------+ But if I run /usr/local/dovecot/sbin/dovecot --exec-mail ext /usr/local/dovecot/libexec/dovecot/expire-tool.sh --test I get the following output: Info: Loading modules from directory: /usr/local/dovecot/lib/dovecot/imap Info: Module loaded: /usr/local/dovecot/lib/dovecot/imap/lib10_quota_plugin.so Info: Module loaded: /usr/local/dovecot/lib/dovecot/imap/lib20_expire_plugin.so Info: Quota root: name= backend=maildir args= Info: expire: pattern=INBOX type=expunge secs=5184000 Info: expire: pattern=Spam type=expunge secs=5184000 Info: expire: pattern=Papierkorb type=expunge secs=5184000 Info: expire: pattern=Trash type=expunge secs=86400 Info: auth input: quota_rule=*:storage=10000 Info: auth input: home=/var/mailstore/09/test Info: auth input: mail=maildir:/var/mailstore/09/test/mail Info: Namespace: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes Info: maildir: data=/var/mailstore/df/rrosenfeld/mail Info: maildir++: root=/var/mailstore/df/rrosenfeld/mail, index=, control=, inbox=/var/mailstore/df/rrosenfeld/mail Info: test/Trash: no messages left Info: test/Spam: stop, expire time in future: Sat Mar 6 12:35:10 2010 As you can see, it uses my username (rrosenfeld) instead of the username "test", whose mailbox should be expired.

It also returns the correct home and mail attributes (the above messages were triggered by my expire call!). I tried out to comment out the mail_location from dovecot.conf to make sure that the mail attribute from userdb is used, but this has the effect, that dovecot expire does not know any mail location setting at all and tries some "home" directories and different mail storage formats while my setting mail=maildir:/var/mailstore/09/test/mail from the userdb is completely ignored: Info: Loading modules from directory: /usr/local/dovecot/lib/dovecot/imap Info: Module loaded: /usr/local/dovecot/lib/dovecot/imap/lib10_quota_plugin.so Info: Module loaded: /usr/local/dovecot/lib/dovecot/imap/lib20_expire_plugin.so Info: Quota root: name= backend=maildir args= Info: expire: pattern=INBOX type=expunge secs=5184000 Info: expire: pattern=Spam type=expunge secs=5184000 Info: expire: pattern=Papierkorb type=expunge secs=5184000 Info: expire: pattern=Trash type=expunge secs=86400 Info: auth input: quota_rule=*:storage=10000 Info: auth input: home=/var/mailstore/09/test Info: auth input: mail=maildir:/var/mailstore/09/test/mail Info: Namespace: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes Info: cydir: mailbox location not given Info: cydir: Couldn't create mail storage : Root mail directory not given Info: dbox: mailbox location not given Info: dbox: Couldn't create mail storage : Root mail directory not given Info: maildir: access(/var/mailstore/09/test/Maildir, rwx): failed: No such file or directory Info: maildir: couldn't find root dir Info: maildir: Couldn't create mail storage : Root mail directory not given Info: mbox: root exists (/var/mailstore/09/test/mail) Info: mbox: INBOX: access(/var/mail/test, rw) failed: No such file or directory Info: mbox: INBOX: access(/var/spool/mail/test, rw) failed: No such file or directory Info: mbox: INBOX defaulted to /var/mailstore/09/test/mail/inbox Info: fs: root=/var/mailstore/09/test/mail, index=, control=, inbox=/var/mailstore/09/test/mail/inbox Info: test/Trash: no messages left Info: test/Spam: stop, expire time in future: Sat Mar 6 12:35:10 2010 As you can see, expire tries to access different (default?) mailbox typies instead of simply using maildir:/var/mailstore/09/test/mail as defined in the userdb. So my main problem seems to be, that the mail attribute from the userdb is completely ignored in expire calls. But how do I fix this?

[Dovecot] Dovecot-deliver sometimes fails when message set to discard via sieve
by Steve Wagner 19 Jan '10

19 Jan '10

Hi, sometimes mails that i discard via sieve gets delivered to my inbox and i can not figure out why. So i hope you can give me a hint. My setup is: I use a self compiled dovecot 1.2.4 with installed sieve and managesieve plugin. Incoming mails a processed by Postfix and the delivered to Procmail. Procmail invokes Spamassassin and discard all mails marked as spam. The other mails are passed to Dovecot deliver this way: :0 w | /opt/dovecot/libexec/dovecot/deliver For moving mails to subdirectorys this works always, but not for mails that are discard via Sieve. Examples are: if header :contains "List-Id" "git.vger.kernel.org" { if header :contains "Subject" "[ANNOUNCE]" { fileinto "Announce"; stop; } if header :contains "Subject" "[ANN]" { fileinto "Announce"; stop; } if header :contains "Subject" "[PATCH" { discard; stop; } fileinto "Lists.Git"; stop; } or if header :contains "Organization" "web.de" { discard; stop; } This often works, but sometimes it fails. Procmail reports then that deliver reported an error (but not which) and delivers them to my inbox. There are also no message in dovecots or dovecot delivers log file. Dose anybody have an idea?

19 Jan '10

Hi, I want to configure dovecot as gmail imap proxy. If any system in my network wants to connect to imap.gmail.com,993 it has to go through the dovecot proxy. Is it possible to setup such environment with dovecot? If yes, can you please help me to configure my dovecot server. Warm Regards Supratik

Hi all, is there some easy way to inform Dovecot about a new delivery, which has happened after postfix invoked maildrop, so the index files would be updated?

[Dovecot] Socket permission 432/384 and dovecot.conf
by Seba 19 Jan '10

19 Jan '10

Sorry for that question but: when you set in dovecot.conf this for example: socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } and you run "dovecot -n" you'll see client: path: /var/spool/postfix/private/auth mode: 432 I'm wondering about the mode "432" - how is this value calculated? Same for the auth/master socket socket - the value ist "384" and in dovecot.conf it's 0600. Thanks for any info. Seba

[Dovecot] Dovecot Proxy and environment variables
by BaQs 19 Jan '10

19 Jan '10

Dear list, First of all, I am French so excuse my bad english. I am currently using dovecot proxy feature, using sql backend. I "proxy" the imap/pop requests to another server, let's say server2. On server2, I use a script to keep up to date a "pop before smtp auth" database. I used mail_executable = /path/to/this/script.sh ... My problem is: the $IP environment variable on server2 is the proxy's IP. How could I give a variable from proxy to server2, or simply get the real client public IP ? Thanks a lot in advance for your answers Pierre. PS: let me also thank very much dovecot developers and community !

[Dovecot] No filelocking at "shared-mailboxes" dictionary?
by Peer Heinlein 19 Jan '10

19 Jan '10

Using imapsync I changed many ACLs on many accounts simultaneously in four concurrent IMAP-sessions. I started with an empty file "shared-mailboxes". But after the sync the file "shared-mailboxes" has been crashed. I found broken lines and I'm missing some entrys. Is it possible that there's no filelocking on that file? I used the ext3 filesystem. That's what shred-mailboxes looks like at the moment: shared/shared-box 1 shared/shared-boxes/user/user1.example.com/user2.example.com 1 .example.com/user5.example.com 1 hared/shared-boxes/user/user6.example.com/user4.example.c2442203233424^? 1 ser/user7.example.com/user2.example.com Peer dovecot -n: # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.39-0.2-default x86_64 openSUSE 11.1 (x86_64) protocols: imap imaps managesieve ssl_cert_file: /etc/ssl/old.pem ssl_key_file: /etc/ssl/old.pem shutdown_clients: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(managesieve): /usr/lib/dovecot/managesieve-login login_process_per_connection: no login_max_processes_count: 512 max_mail_processes: 1024 mail_max_userip_connections(default): 40 mail_max_userip_connections(imap): 40 mail_max_userip_connections(managesieve): 10 verbose_proctitle: yes mail_uid: vmail mail_gid: vmail mail_location: maildir:~/Maildir mail_executable(default): /usr/lib/dovecot/imap-usernamenmigration mail_executable(imap): /usr/lib/dovecot/imap-usernamenmigration mail_executable(managesieve): /usr/lib/dovecot/managesieve mail_plugins(default): quota imap_quota acl imap_acl mail_plugins(imap): quota imap_quota acl imap_acl mail_plugins(managesieve): mail_plugin_dir(default): /usr/lib64/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib64/dovecot/modules/imap mail_plugin_dir(managesieve): /usr/lib64/dovecot/modules/managesieve namespace: type: private separator: / inbox: yes list: yes subscriptions: yes namespace: type: shared separator: / prefix: zz_SHARED_ACCOUNTS/%%u/ location: maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u list: yes lda: postmaster_address: postmaster(a)iea-dpc.org mail_plugins: quota acl sieve mail_plugin_dir: /usr/lib64/dovecot/modules/lda quota_full_tempfail: yes auth default: mechanisms: plain login digest-md5 cram-md5 verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot/userdb userdb: driver: passwd-file args: /etc/dovecot/userdb userdb: driver: static args: uid=5001 gid=5001 socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: vmail plugin: quota: maildir quota_rule: *:storage=102400 acl: vfile acl_shared_dict: file:/var/lib/dovecot/shared-mailboxes sieve: ~/.dovecot.sieve sieve_dir: ~/sieve -- Heinlein Professional Linux Support GmbH Linux: Akademie - Support - Hosting http://www.heinlein-support.de Tel: 030 / 40 50 51 - 0 Fax: 030 / 40 50 51 - 19 Zwangsangaben lt. §35a GmbHG: HRB 93818 B / Amtsgericht Berlin-Charlottenburg, Geschäftsführer: Peer Heinlein -- Sitz: Berlin

[Dovecot] Upgrade path questions
by Thomas M Goerger 18 Jan '10

18 Jan '10

Hi, We are currently running Dovecot v1.1.6 on our servers, and are contemplating an upgrade to 1.2, or 2.0 soon. We are wondering how many organizations are still running a 1.1 version of Dovecot, and if anyone has any thoughts on this transition. Have you upgraded from 1.1 to 1.2? What are your experiences with this? Have you upgraded from 1.1 to 2.0 directly? What are your experiences this way? We are also running an environment with both mbox and maildir formats. How many of you are running similarly, or are running solely maildir or mbox? We're just looking to gather information going forward, and anything you might be able to contribute would be very helpful. Thanks! ************************************************************************* * Tom Goerger - Email/Unix System Administrator * * * * University of Minnesota Email: tmg(a)umn.edu * * Operations, Infrastructure and Architecture Phone: 4-5804 * * Internet Services Office: 626J WBOB * * * *************************************************************************

[Dovecot] how-to use dsync to do a 2 ways replication ?
by Eric Belhomme 18 Jan '10

18 Jan '10

Hi, I want to set-up two dovecot imap servers, with active-active replicated maildirs. The goal is to have a hosted public server on Internet, and a private server on my LAN to speed-up local connections. So I compiled dovecot 2.0 beta 1 in order to use dsync utility... Actually my config is pretty simple as I just want to setup a proof of concept before going ahead in this way : (Both servers are Debian Lenny with excatly the same config) mail0:~# /usr/local/dovecot2/sbin/dovecot -n # 2.0.beta1: /etc/dovecot2/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.3 auth_debug = yes auth_verbose = yes login_trusted_networks = 172.16.64.0/18 mail_location = maildir:%h passdb { args = /etc/dovecot/userpasswd deny = no driver = passwd-file } postmaster_address = postmaster(a)example.com service pop3-login { inet_listener { port = 110 } inet_listener { port = 995 ssl = yes } } service imap-login { inet_listener { port = 143 } inet_listener { port = 993 ssl = yes } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/userpasswd driver = passwd-file } I logged on the first server with an IMAP client then I copied many email through IMAP, then I launched dsync as root : /usr/local/dovecot2/bin/dsync -v mirror 'ssh eole.it.fr.eve /usr/local/dovecot2/bin/dsync' root(a)eole.it.fr.eve's password: dsync-local(root): Error: Can't create mailbox ssh: Mailbox already exists dsync-local(root): Error: Can't create mailbox aptitude: Mailbox already exists dsync-local(root): Error: Can't create mailbox debtags: Mailbox already exists dsync-local(root): Info: debtags: only in source dsync-local(root): Info: aptitude: only in source dsync-local(root): Info: ssh: only in source dsync-local(root): Info: ssh: only in dest dsync-local(root): Info: aptitude: only in dest dsync-local(root): Info: debtags: only in dest dsync-local(root): Error: Mailbox ssh changed its GUID (cdfc9a2d85154e4b47180000b31a5865 -> 541e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: msg iteration failed: Couldn't open mailbox dsync-remote(root): Error: Can't create mailbox debtags: Mailbox already exists dsync-remote(root): Error: Can't create mailbox aptitude: Mailbox already exists dsync-remote(root): Error: Can't create mailbox ssh: Mailbox already exists dsync-remote(root): Error: Mailbox debtags changed its GUID (501e9f2850234e4b3a2b0000d0cf7273 -> d1fc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: msg iteration failed: Couldn't open mailbox dsync-remote(root): Error: command MSG-LIST failed dsync-local(root): Error: Mailbox ssh changed its GUID (cdfc9a2d85154e4b47180000b31a5865 -> 541e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox aptitude changed its GUID (cffc9a2d85154e4b47180000b31a5865 -> 521e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox debtags changed its GUID (d1fc9a2d85154e4b47180000b31a5865 -> 501e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox ssh changed its GUID (cdfc9a2d85154e4b47180000b31a5865 -> 541e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox aptitude changed its GUID (cffc9a2d85154e4b47180000b31a5865 -> 521e9f2850234e4b3a2b0000d0cf7273) dsync-local(root): Error: Mailbox debtags changed its GUID (d1fc9a2d85154e4b47180000b31a5865 -> 501e9f2850234e4b3a2b0000d0cf7273) mail0:~# dsync-remote(root): Error: Mailbox debtags changed its GUID (501e9f2850234e4b3a2b0000d0cf7273 -> d1fc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox aptitude changed its GUID (521e9f2850234e4b3a2b0000d0cf7273 -> cffc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox ssh changed its GUID (541e9f2850234e4b3a2b0000d0cf7273 -> cdfc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox debtags changed its GUID (501e9f2850234e4b3a2b0000d0cf7273 -> d1fc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox aptitude changed its GUID (521e9f2850234e4b3a2b0000d0cf7273 -> cffc9a2d85154e4b47180000b31a5865) dsync-remote(root): Error: Mailbox ssh changed its GUID (541e9f2850234e4b3a2b0000d0cf7273 -> cdfc9a2d85154e4b47180000b31a5865) It seems dsync tries to use my system user database instead of the /etc/dovecot/userpasswd file !

[Dovecot] Adding support for a new storage format - plugin?
by Brad Hards 18 Jan '10

18 Jan '10

Hi, I've spent a little bit of time looking at the dovecot source (from the unstable 2.0 development tree), and I think I'm starting to get it together... Background: I'm interested in dovecot to provide IMAP access to an existing database backed server store (http://www.openchange.org for more details). The goal is to provide parallel access using either IMAP or the exchange RPC protocol. If I understand this stuff: * I can potentially provide access to the store using a plugin. It looks like the virtual mailbox plugin is a potential example here. * I may need to also provide an authentication plugin (not sure whether I can just re-use the existing ldap backend - quite possibly a useful option in my scenario) * I probably can't use the existing SQL code, since it uses its own schema. * I may need to provide some locking to ensure things are always in a consistent state for both IMAP and exchange RPC. Comments? Suggestions? Brad

[Dovecot] listen to imap*s* on multiple ports?
by Frank Cusack 17 Jan '10

17 Jan '10

<http://wiki.dovecot.org/QuestionsAndAnswers#Is_it_possible_to_have_Dovecot_…> is out of date. How can I listen to ssl-wrapped IMAP on multiple ports? I need to listen on both 993 (for some stupid clients I have to support that can't do START TLS) and 80 (to get past L3/L4 firewalls). I'd like to do it in dovecot rather than use nc, ipfilter or whatever. -frank

[Dovecot] handling filename of compressed messages
by Leonardo Rodrigues 17 Jan '10

17 Jan '10

i'm running dovecot 1.2.9 and, among other things, i have the zlib plugin enabled. A shell script runs once a day to compresses all not still compressed files on the users maildirs. so far so good, it works fine, there's no problem on that. what i think is not happening 100% correctly is the following: 1) user receives a message 2) BEFORE the compress routine runs, filename is: new/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207 3) AFTER the compress routine, filename is now: new/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz 4) user check his mail .... and now the filename is cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,S 5) user replies that mail .... and now the filename is cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,RS i'm aware that dovecot doesnt need the '.gz' extension on the file to recognize that as a gzipped file. Even without the .gz extension, dovecot is correctly reading the file. the '.gz' is not even necessary on the filename and still dovecot can handle it fine. anyway, i would like to suggest dovecot to handle the filename to keep the .gz extension, if that exists. This could help sysadmins to easily identify gzipped files on the maildirs and make anything with them, if that's desired. i would like to see dovecot changing filenames properly and keeping the .gz extension always, for example cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207:2,S.gz instead of cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,S cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207:2,RS.gz instead of cur/1263436052.V6814I43300b4M146002.correio.domain.com.br,S=238207.gz:2,RS -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

[Dovecot] shared namespace bug?
by Patrick Kaiser 14 Jan '10

14 Jan '10

Hi, finally i got shared namespace up and running. But for example if user peter.griffin shares his inbox to another user, the LIST "" "*" output on telnet looks like: a02 LIST "" "*" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\Noselect) "/" "shared/peter.griffi" * LIST (\HasChildren) "/" "shared/peter.griffin" * LIST (\HasNoChildren) "/" "shared/peter.griffinINBOX" a02 OK List completed. To share the inbox I previously run as logged in user peter.griffin a02 SETACL inbox peter.griffin lwxrk If I look in thunderbird, i can see under "share" two folders: peter.griffi and peter.griffin. Have i made something wrong, or is this a bug? Hope someone can help me. thanks, patrick -- Name : Patrick Kaiser Email : patrick.kaiser(a)argonius.de Phone : +49 (178) 8452388 Website : http://www.argonius.de GPG Key : http://www.argonius.de/key.pub

[Dovecot] uw-imap compatability hack?
by Simon Annetts 14 Jan '10

14 Jan '10

Hi all Apologies if this question has already been asked before... I'm migrating from a uw-imap setup where the mail folders were in a subdir mail/ in the users' home directories. All of the clients are configured with 'IMAP server directory' set to mail/ (Thunderbird) and it would be difficult to change this on the clients (there are 1000s of them) I want to use maildir and I have converted the original mbox files in ~mail/ to maildir format. So in ~Maildir/ I now have: cur dovecot.index dovecot.index.cache dovecot.index.log dovecot-uidlist .Drafts new .Sent-Items .Spam subscriptions tmp .Trash if I remove the mail/ setting from 'IMAP server directory' in the client, then everything works as expected and all the folders are visible. With this setting in however, only the inbox is visible and attempts to click on another folder, say Trash result in the client error: Mailbox doesn't exist .mail.Trash I've tried various namespace configurations I found in the namespaces wiki example but none seem to work. What I would really like to happen is for dovecot to ignore this setting supplied by the client and not to prepend .mail onto the folders it is looking for. Is there a clever namespace that will do this for me, or some other setting or symlink trickery? Ultimately I want to support clients that might have both mail/ and nothing set in this box.

Is there any way to tell dovecot to listen for imap/imaps requests on all interfaces on multiple separate ports? For example, can I do this: protocol imap { listen = *:10143 listen = *:143 ssl_listen = *:10993 ssl_listen = *:993 ... } Thanks! Rick

[Dovecot] Sieve and ManageSieve for Dovecot v2.0 merged into one repository
by Stephan Bosch 13 Jan '10

13 Jan '10

Hi, I've merged the Mercurial repositories for Sieve and ManageSieve for Dovecot v2.0 into one repository: http://hg.rename-it.nl/dovecot-2.0-pigeonhole This simplifies the build process significantly. It also allows tightly integrating the implementation of the script storage with the main Sieve library, enabling the possibility to implement alternate means of script storage, like for instance a SQL or LDAP database. Building ManageSieve is still optional as outlined in the INSTALL file. The old v2.0 repositories will be archived soon. I'm slowly but surely progressing towards a first Pigeonhole release for Dovecot v2.0. Regards, Stephan

[Dovecot] Allow POP3 per Domain
by Hauke Hagedorn 13 Jan '10

13 Jan '10

Hi List, I wonder, if it is possible to "switch" POP3 on or off for specific domains. Actually I want to disallow POP3-logins for a certain domain, whereas users can still login into a webinterface via IMAP. Curently I use Dovecot 1.1.11 on current Ubuntu 9.10 with a mySQL backend for authentication. With kind regards Hauke

[Dovecot] Discard duplicate messages at delivery?
by Nicolas KOWALSKI 12 Jan '10

12 Jan '10

Hello, I am using dovecot 1.2.9, and the sieve plugin for filtering incoming messages into specific folders. The MTA is postfix, and deliver is called using the "mailbox_command = /usr/lib/dovecot/deliver" directive. Is it possible to make dovecot's deliver discard duplicate messages? With cyrus there is a duplicatesuppression directive which works well (http://cyrusimap.web.cmu.edu/imapd/overview.html#duplicate) With procmail, this can be done with the following recipe, but I did not found an equivalent for dovecot: # One often receives duplicate messages for cross-postings to mailing # lists, or explicit replies to a post from you in addition to the # mailing list message. # # The following recipe eliminates all duplicate messages. It tells # formail(1) to keep a cache file of the Message-IDs of the most # recent messages you've received.

[Dovecot] Silent migration from mbox to maildir?
by Götz Reinicke - IT-Koordinator 12 Jan '10

12 Jan '10

Hi, after migrating to a new hardware (which is soo soooo mutch faster than the old one) I start to think about migrating from mbox to maildir. I'v read some docs and wikies and some questions are unanswered or maybe I skip the answers: - Is it possible to migrate the mboxes "silent" e.g. if a user logs in the mbox is converted? - regarding the Namespaces wiki article, it is possible to mix mbox and Maildir for one user. Is it possible to use this setup for all newly created accounts? or - Is it possible to have maildir set up for all newly created accounts while the old accounts still use mbox? Thanks for any suggestion and best regards, Götz -- Götz Reinicke IT-Koordinator Tel. +49 7141 969 420 Fax +49 7141 969 55 420 E-Mail goetz.reinicke(a)filmakademie.de Filmakademie Baden-Württemberg GmbH Akademiehof 10 71638 Ludwigsburg www.filmakademie.de Eintragung Amtsgericht Stuttgart HRB 205016 Vorsitzende des Aufsichtsrats: Prof. Dr. Claudia Hübner Staatsrätin für Demographischen Wandel und für Senioren im Staatsministerium Geschäftsführer: Prof. Thomas Schadt

[Dovecot] Dovecot Quota Problem
by Ken Price 12 Jan '10

12 Jan '10

I'm using Dovecot LDA with Exim. I'm also using Dictionary Quotas in a MySQL database. I want to avoid backscatter completely, so I set "quota_full_tempfail = yes" and handle quota checking in the Exim RCPT ACL during the SMTP session. The problem lies in the case where a user's account is nearly full. Smaller messages will continue to come through, but a larger message would get queued for retry since it will push the account over quota. I need Dovecot's quota to exhibit the same behavior as Exim's "quota_is_inclusive=false". >From Exim docs: quota_is_inclusive=false When this is done, the check for exceeding the quota does not include the current message. Thus, deliveries continue until the quota has been exceeded; thereafter, no futher messages are delivered. Any ideas on how I can implement this inside of Dovecot? Thanks, -Ken Price

[Dovecot] Problem in LSUB?
by Sergio Villar Senin 12 Jan '10

12 Jan '10

Hi guys, I'm not 100% sure about the dovecot version in the server because I don't have access to it, just an account, but I think it's 1.1-rc4 I'm an email client developer and I have a doubt about the behaviour of LSUB that I think it's buggy. See this chat with the server 40 LIST "" INBOX * LIST (\HasChildren) "." "INBOX" 40 OK List completed. 41 LIST "" INBOX* * LIST (\HasChildren) "." "INBOX" * LIST (\HasNoChildren) "."

[Dovecot] Dovecot (IMAP) Hangs sometimes
by Mario Gomide 12 Jan '10

12 Jan '10

Hi there! I'm using Dovecot 1.0.7 in RHEL 5.4 64bits as a IMAP/POP3 server. Dovecot authenticates users against an AD server via kerberos (pam configuration) and clients connect to it via IMAPs and POP3s with SSL. Webmail is in localhost and connects locally also with SSL. All is fine and people use the email server normally and with no problems. But, I have noticed that dovecot hangs sometimes. Usually twice a day somewhere between 09:40 and 10:00 a.m and in the afternoon at about 3:00 p.m. The problem starts when webmail takes long to authenticate and show folders and stuff. After a while it times out and doesn't connect. Then the clients (e.g. outlook, thunderbird) start taking long to connect and then they timeout. Important: Only IMAP connections timeout! POP3 continues ok. This latency keeps on going until dovecot finally hangs (after about 10 to 15 minutes). The problem is solved when I restart/reload dovecot. I'm not sure as to what's going on! I check the log, but it has been hard to pinpoint an exact event or to detect when the problem begins. Any ideas? BTW: what's the real difference between reload and restart? Thanks a lot! Mario

Thanks Stephan, I have the extdata plugin compiled, and am now trying to make a global sieve script to test it. I'm running into problems when using sievec to compile the script - I'm not getting the plugin's variables that are provided in dovecot.conf's plugin {}.

I've traced the process, there's no attempt to open or stat any dovecot.conf 2. using tip dovecot-1.2, dovecot-1.2-sieve, pigeonhole-sieve-extdata. I pulled+updated & rebuilt and confirmed the above behaviour just prior to sending this message. 3.

[Dovecot] Same filenames on different servers?
by Alexander Chekalin 11 Jan '10

11 Jan '10

Hi, I'm really fuzzy about some problem on how Dovecot used to name files to store messages in Maildir. I have two identical servers (let's call them "First" and "Second"), and have Dovecot and Exim set up on both of them (Maildirs are used to store messages and boxes). First server is the server to be used by people around, and the Second server is backup one, the only thing it can do while the First is alive is to get (via rsync) First's mail spool. I set up rsync to run every 5 minutes, and that's quite well sync spools from First to Second. So if something wrong happens to First server we simple disconnect it from the network and put Second server in place of First. The problem is that files in Maildirs on First server are named like that: 1262610335.H798006P5447.first.domain.my,S=1962:2, 1262610402.H529761P5596.first.domain.my,S=2975:2, 1262610410.H787724P5657.first.domain.my,S=75691:2, ... and the files on Second server should be named like 1262610335.H798006P5447.second.domain.my,S=1962:2, 1262610402.H529761P5596.second.domain.my,S=2975:2, 1262610410.H787724P5657.second.domain.my,S=75691:2, ... As soon as I enter the Second's mailbox with IMAP client Dovecot used to rename files the way they should be. If after that I rsync spools I'll end up with double sized spool as there'll be both First and Second files: 1262610335.H798006P5447.first.domain.my,S=1962:2, 1262610335.H798006P5447.second.domain.my,S=1962:2, 1262610402.H529761P5596.first.domain.my,S=2975:2, 1262610402.H529761P5596.second.domain.my,S=2975:2, ... Long description for simple problem, yes :) I also tried to set: maildir_copy_preserve_filename = yes but still no luck. My setup is FreeBSD 7.2 with all versions in 1.1.x and 1.2.x branches (now it is 1.2.8). Thank you in advance for you advice, yours, Alexander

[Dovecot] sieve 0.1.14: vacation encodes Subject twice
by Roland Rosenfeld 11 Jan '10

11 Jan '10

Hi! I noticed the following problem in dovecot-1.2-sieve-0.1.14: The following vacation causes trouble with the Subject line: if not exists ["List-Id", "List-Post"] { vacation :days 7 :addresses ["test(a)netcologne.de"] :subject "=?utf-8?b?w4TDlsOc?= sadasd" "Bin gerade nicht hier."; } As you can see, the Subject is already MIME encoded according to RFC2047. Starting with sieve 0.1.14 the subject is now encoded by sieve again, so I get the following in my vacation mail: Subject: =?utf-8?q?=3D=3Futf-8=3Fb=3Fw4TDlsOc=3F=3D?= sadasd As you can see, the RFC2047 encoding is RFC2047 encoded, which results in an unreadable subject. According to RFC5230 section 4.3 this shouldn't happen: The ":subject" parameter specifies a subject line to attach to any vacation response that is generated. UTF-8 characters can be used in the string argument; implementations MUST convert the string to [RFC2047] encoded words if and only if non-ASCII characters are present. Implementations MUST generate an appropriate default subject line as specified below if no :subject parameter is specified. If I understand this right, sieve should do the RFC2047 encoding only if the string is non-ASCII. But the RFC2047 encoded string is already ASCII, so it should not be encoded a second time. I just compared this with sieve 0.1.13, which behaves different: It does not encode the Subject header at all. As long as the managesieve client (in our situation Horde/IMP) encodes the subject, everything works correct, while we run into trouble with 0.1.14. I think that there needs to some mechanism in sieve that checks whether the subject contains non-ASCII and does the encoding only in this case. I just checked out, that 0.1.14 does not encode a non RFC2047 encoded 7bit subject, while a 7bit subject starting with =?utf-8?... is encoded twice.

[Dovecot] How to create UTF encoded folders?
by Kārlis Repsons 11 Jan '10

11 Jan '10

Hey, as I understand from post [1], system folders with UTF-8 chars in their names will only be available for use with Dovecot2 and I certainly look forward to that, but somehow I was short of info about the current use of UTF characters like ā, Ž etc. Should I just omit thinking about modified-UTF-7, avoid those characters for the time being and then with Dovecot2 create UTF-8 encoded folders with MUA and also on fs? Or there is something to know anyway? Please suggest as it would be a pity not to create folders with utf symbols... [1] http://www.mail-archive.com/dovecot@dovecot.org/msg23576.html

[Dovecot] "leave mail on server" workaround
by Kirill Miazine 11 Jan '10

11 Jan '10

Hello, POP users often keep fetched mail on server, by checking for "leave mail on server" or similar option in their client. What would be the best way to disallow them using such approach. That is, what is the best way to force deletion of messages that have been RETRieved in a POP session at the end of that POP session? RETRieved messages will be marked as \Seen, but since users might also use an IMAP client (e.g. webmail), it'll be dangerous to simply delete all \Seen messages in user's mailbox. I'm all open for suggestions. -- -- Kirill Miazine <km(a)krot.org>

[Dovecot] How to tell dovecot to use a specific MTA
by Spyros Tsiolis 10 Jan '10

10 Jan '10

Hello again people, OK. I checked a lot of HOWTOs and documents. One specific document describes how one can make dovecot "talk" to postfix. The procedure is pretty straightforward (taken from the document) : -- . Configuring Postfix and Dovecot Turn off sendmail: service sendmail stop chkconfig sendmail off system-switch-mail (select postfix) -- This is for CentOS systems. My question is pretty simple. How exactly does someone tell dovecot (or the CentOS system) that the MTA used is not a pre-packaged postfix MTA but (in my case as you have pretty much discovered by now) XMail compiled from source (no pre-packaged version AFAIK for CentOS; but even if existed, I would still build it on my own) ?

[Dovecot] IMAP client dependence on dovecot mail storage fromat?
by Kārlis Repsons 09 Jan '10

09 Jan '10

Hi, After setting up a maildir tree with :LAYOUT=fs and accessing it with KMail and Thunderbird, various mail client-specific problems appeared, but, as I didn't try with maildir++, I would like to confirm here: does that matter for an IMAP client much if I store mail on server as ":LAYOUT=fs" or maildir++? Can it see differences? I would like to think, that IMAP protocol should provide for all transactions in a standard way and its dovecot's/server's sole business how it stores mail locally. However... These results seem not very good: KMail: try creating a folder "sub" in "parrent" and you'll get "parrent.sub" along with "parrent" on server side. There, however, are no problems with Latvian unicode chars. Thunderbird: it can create a new folder in "parrent" as desired, but it can't display Latvian unicode chars (being such at server side) on client, while, if I try creating a new folder with Thunderbird with these chars, on server it will look somewhat like base64! So I'm really confused. All together these things are pretty frustrating, sure, but I'd like to understand whats the real problem here!

[Dovecot] Sieve > Pigeonhole > external storage with LDAP or other data source available to dovecot
by Martin F. Foster 09 Jan '10

09 Jan '10

I am looking at porting and generalizing an old in-house patch that I'm using for the CMU Sieve plugin. It allows sieve script to test & lookup arguments from LDAP. Before getting too involved in this, I'd like to discuss my goals here in the hopes that someone else also thinks this would be useful. Many heads may make better design? Goal: ------ Allows scripts which are still stored on the filesystem to lookup parameters stored in an LDAP directory. Useful if you provide a global sieve script to implement functions such as "vacation", forwarding to small groups (not a MLM), wish to toggle whether a message is kept in the mailbox after being forwarded, etc. <example> # determine if we always auto-respond, or if we respond with a more vacation-ish setting of every 30d # # sample LDAP entry: # uid: testuser(a)domain.com # mailResponderMode: vacation # mailResponderText: "I'm on vacation, far far from the Internet" (base64 encoded string...) # "always" reply mode, sanitized to once a day if ldap "mailResponderMode" "reply" { vacation :days 1 "ldap@mailResponderText"; } # traditional "vacation" mode, say reply once every 30d if ldap "mailResponderMode" "vacation" { vacation :days 30 "ldap@mailResponderText"; } </example> This introduces: 1. a new command "ldap", to lookup attributes and their values in an LDAP directory using the user's context 2. an extention to the vacation command that looks up the vacation reply text that is triggered by supplying "ldap@ldapAttribute" as the text. 3. other actions not shown above which extends redirect and a few other commands to lookup data from LDAP Related work: 1. Pigeonhole low priority TODO would like to implement alternate script storage, eg: LDAP & SQL. I'm not immediately interested in alternate types of script storage, but for what I want to acheive, I need to sanely access at least an LDAP directory. 2. draft-ietf-sieve-external-lists (http://tools.ietf.org/html/draft-ietf-sieve-external-lists-01) proposes a mechanism to pull mailing list addresses from external storage mechanisms such as LDAP, ACAP or relational databases. I'm interested in this, but would like to extend this functionality beyond just lists as the example above demonstrates. 3. there are security and resource consumption issues with doing this, suggesting that limits should be set, or the use may have to be restricted to global scripts eg: sieve_before or sieve_after The question: - do others on this list see value in the functionality described above? If there's some consensus that this would be useful, I'll flesh out howI think a generalized version of this old patch may behave, then (!) work on an implementation as a plugin to dovecot's sieve. cheers, -Martin Foster martin_foster(a)pacific.net.au martin.foster(a)pacnet.com

there is a windows tool that strips attachments from emails on the server. i think it works for exchange. is there a tool or a way to do this for imap? i don't mean a mail filter that would strip them before the user sees them, i mean that the user could actively cooperate to reduce mail storage space, yet keep the original email on the server sans attachment.

[Dovecot] shared namespace problem
by Patrick Kaiser 08 Jan '10

08 Jan '10

Hi List, I've got a problem, setting up shared namespaces. I am trying to setup a Mailbox (Maildir) which is accessible for some users. (For example mailbox "sales" and only sales representive have access to it) Mailboxes can be found under /var/vmail/<username>, whereas <username> looks like foo.bar or peter.griffin ;) Now, if I connect via telnet, loggin in as foo.bar and run a03 SETACL foobar peter.griffin lwrxk everything seems fine. Under /var/vmail/foo.bar is a acl-file dovecot-acl-list Under /var/vmail/foo.bar/.foobar is a acl-file dovecot-acl The contents looks ok. Also there is a generated file /var/vmail/shared-mailboxes.db. But if i now loggin in as peter.griffin and setup command a03 LIST "" "*" or a03 LIST "" "#shared" I can not find any shared mailbox.

[Dovecot] Dovecot Sieve: Vacation Recipient
by Lukas Kolbe 08 Jan '10

08 Jan '10

Hi! I tried to use the sieve vacation plugin, but we're facing a little problem: our user's addresses are <uid>@<domain>, and if they want to use imap and sieve, they can have a forward to <uid>@imap.<domain>. The return-path, and hence the address the vacation message is sent to, is then <uid>@<domain> and not the original sender of the message. Is there any way to circumvent this? Sending a vacation back to oneself doesn't really make sense here :) Oh, and happy new year and thank you all for this great piece of software! -- Lukas

Well, there might be scenarios, when a local user other than root may sniff the connection on localhost, but I think you have no such one. So to encrypt a connection from localhost to localhost is a waste of ressources. In case of Dovecot you'll need one extra file descriptior (and depending on your settings one extra process as well), plus the CPU time to actually do the encryption. > Yeah.

The webmail-frontend _is_ your client in the view of Dovecot. But since the cert is in /etc/ssl/certs, it should work, but if you validate the cert, the webmail may bark, because you access the SSL-cert with the CN "webmail.domain.gr" by another name "localhost". This is a sign of a man-in-the-middle attack, actually. BTW: Do your SSL IMAP/POP clients also use the name "webmail.domain.gr"? Otherwise they will get a warning as well, maybe each time they connect.

[Dovecot] First time Dovecot user, really impressed so far. What is best IMAP enabled webmail package to go with Dovecot?
by Stan Hoeppner 08 Jan '10

08 Jan '10

Greetings everyone, I'm new to the list as of today. I just installed Dovecot a couple of days ago for the first time, Debian Lenny Dovecot v1.0.15-2.3. So far I'm pretty impressed. I'm using mbox format with Dovecot auto-deciding to place mail in user home directories, which is great. It works very well with the Win32 Thunderbird 3 client over a small basic 100FDX switched net. I've got one list mail folder with 10,600 messages and server side body searching that folder via T-Bird is very quick, on the order of 5 seconds. It would probably be quicker if Dovecot threaded the search to use both CPUs, but pegging just the one CPU the search is still very darn quick. And this is on a dual P2-550 class machine with only 384MB RAM and a single 500GB 7200RPM SATA drive. I'd like to install a webmail package on the same host. I used Squirrelmail for this purpose many years ago and I wasn't wholly impressed with the user interface. I'm also not impressed by the fact that I regularly receive spam from compromised Squirrelmail hosts/accounts. I really like the look/feel of the Scalix Web Access AJAX based interface, but I can't/won't use Scalix as it's not supported on Debian, it has more features than I need, and the system requirements are a bit steep. So, what's the best FOSS IMAP enabled web mail front end with a modern look/feel? I'd like to run it on lighttpd, which I'm already using, not apache. Thanks in advance for any advice. My apologies if my first post is a little OT, but I figured there's probably no better place to ask about the best webmail front end for Dovecot than here. -- Stan

Does Dovecot Sieve plug-in support Dovecot 2.0? We have a few servers running Dovecot 2.0 beta1, but the Dovecot Sieve plug-in (version 0.1.4) won't compile against it. Is this on the Sieve TODO list? If so, when do you see it will happen? Thanks Wenjie

[Dovecot] Dovecot not delivering mail.
by Anthony Nedland 08 Jan '10

08 Jan '10

I get no errors when attempting to send or receive. However, my messages aren't showing up in the mailboxes. I am sending between users on the same server. This is my dovecot -n output ------------------------------------------------ # 1.1.11: /etc/dovecot/dovecot.conf Error: Error in configuration file /etc/dovecot/dovecot.conf line 1076: Unknown section type (section changed in /etc/dovecot/dovecot.conf at line 1038) Fatal: Invalid configuration in /etc/dovecot/dovecot.conf ----------------------------------------------- I was under the impression that this would be an irrelevant message, as my actual dovecot configuration file is dovecot-postfix.conf rather than dovecot.conf. The logging shows login/logout and no errors. Thanks.

[Dovecot] auth, partially resolved
by Spyros Tsiolis 07 Jan '10

07 Jan '10

Hello people, After a lot of wading through the dovecot documentation (which btw, is excellent !, everything lies under "dovecot/doc/wiki"), I managed to authenticate a couple of accounts. For starters, I want dovecot to work as an imap/imaps box and nothing else. So , I went ahead and created a "passwd" file with two users. One user being my name (spyros) and plaintext password and the other user "postmaster" with encrypted password ("/etc/dovecot/passwd" shown) : --- spyros@webmail.domain.gr:{PLAIN}plainpassword postmaster@webmail.domain.gr:{SSHA}SSHAPassword --- Now, if I telnet to port 143 with both users, the system comes back with the following : --- [root@webmail dovecot]# telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready . login spyros(a)webmail.domain.gr password . OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in --- As I said, it allows login on port 143 for both users. So, the same for "postmaster". Now for port 993 : --- [root@webmail dovecot]# openssl s_client -connect webmail.domain.gr:993 [lots of SSL-related certificate information] * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready . login spyros(a)webmail.domain.gr password . OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in --- Again, the same for user "postmaster". I don't paste. So, everything is fine. However, I have an issue with the (?!) issued certificate. If I check the dovecot logs I find nothing. If on the other hand, I do the same check on the Horde application, It comes back with the following : --- * Trying protocol imap/notls, Port 143: SUCCESS - INBOX has 0 messages (0 new 0 recent) * Trying protocol imap/ssl, Port 993: ERROR - The server returned the following error message: SECURITY PROBLEM: insecure server advertised AUTH=PLAIN[SERVERBUG] Internal error occurred. Refer to server log for more information. [2010-01-05 13:30:12]Certificate failure for localhost: self signed certificate: /C=GR/ST=Kerkyra/L=Kerkyra/O=Tourist Enterprizes/OU=IMAP server/CN=webmail.domain.gr/emailAddress=postmaster(a)webmail.domain.gr * Trying protocol imap/ssl/novalidate-cert, Port 993: SUCCESS - INBOX has 0 messages (0 new 0 recent) * Trying protocol imap/tls/novalidate-cert, Port 143: SUCCESS - INBOX has 0 messages (0 new 0 recent) --- Now, I know I am not supposed to ask you chaps about this, but direct my questions to the horde mailing list. However, I would like an opinion before I go ahead and bug them with this. Certificate was created with "dovecot/doc/mkcert.sh" and the relevant certificate file (can't recall its name at the moment). Any help would be appreciated. On the other hand, If I went too far with this I apologize and I'll try to find another way to resolve this. Thank you people, s.

This could maybe explain some of the coredumps im seeing in 1.2.7? This is on Debian/Lenny, using NFS spool and NFS control/indexes. Timo, you asked in private mail a few days ago if we're sure the filenames are forever unique. Im sure. I double checked it in the source code. The above filenames are timestamp_hostname.pid, and that seems pretty unique right? Regards, Cor

The end result would be something like what follows: Dovecot implementation (proposed): ------------------------------------- <dovecot.conf> dict { dict_sieve = ldap:/etc/dovecot/dovecot-sieve-ldap.conf } plugin { # TODO: proxy this dict? sieve_extsrc = dict } </dovecot.conf> then I'm not sure how you specify multiple hosts with the dict-sql format, so I'm using the postfix convention. there's probably a better way for dovecot. <dovecot-sieve-ldap.conf> map { name = responder_mode server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = responder_mode result_scope = sub bind = no version = 3 } map { name = responder_text server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = responder_text result_scope = sub bind = no version = 3 } map { name = forward_keep server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = mailForwardKeep result_scope = sub bind = no version = 3 } map { # in this case we can have many responses name = forward_addresses server_host = ldap://server1.mycorp.com, ldap://server2.mycorp.com search_base = o=mailstuff query_filter = (&(objectclass=mailschema)(uid=%u)) result_attribute = mailForwardAddress result_scope = sub bind = no version = 3 } </dovecot-sieve-ldap.conf> Sieve language: --------------------- then with proposed new functions of the sieve language (all names plucked out of my head 2hrs ago, would have to think about the semantics some more): 1. a “:list” argument that expects a string-list 2. a “:extsrc” argument that expects an <ext-name: string> and returns a string-list 3. a “:extsrc1” argument that expects an <ext-name: string> and returns a string 4. a new test that uses information that is not in the message, say “arbitrary [comparator] string string” (syntax needs work) sample uses in scripts are then: 1. redirect to a mailing list sourced from ldap (or wheverver): # mailForwardAddress attribute can be present >=0 times redirect :list :extsrc “dict:forward_addresses” 2. decide whether to keep or discard forwarded messages (eg: after the above rule) # mailForwardKeep attribute should only be present once, if at all if arbitrary :is :extsrc1 “dict:forward_keep” “TRUE” { keep; } 3. decide vacation action and text based in information in an ldap dir: # mailResponderMode & mailResponderText attrs should only be present once, if at all if arbitrary :is :extsrc1 “dict:responder_mode” “alwaysreply” { vacation :days 1 :extsrc1 “dict:responder_text"; } if arbitrary :is :extsrc1 “dict:responder_mode” “holiday” { vacation :days 30 :extsrc1 “dict:responder_text”; } ... where the "dict:mapname" syntax would be dovecot implementation specific. could also support the URL & TAG-URI schemes as proposed by draft-ietf-sieve-external-lists. This would allow query URLs as a more general case, using whatever's configured in /etc/ldap/ldap.conf (or whatever the platform's ldap client lib uses). Doing this does raise some resource consumption concerns, hence there should probably be a means of restricting external queries to global scripts only (or sieve_before, sieve_after), and a means of providing timeout values, etc. eg: if arbitrary :is :extsrc1 “ldap:///o=myorg?mailForwardKeep” “TRUE” { keep; } I'll keep on thinking about the design, staring intently at the dovecot sources and http://wiki.dovecot.org/Design for another couple days before attempting to write some code to test this. Feedback on the design of both the sieve language extension, & dovecot interface very appreciated. Cheers, -Martin Foster

[Dovecot] Failed IMAP Login Attempts in Logs
by Carlos Williams 06 Jan '10

06 Jan '10

I had a user telling me that they can't login to the Postfix email server via Webmail (RoundCube) and I decided to see if I could locate this issue in the logs and understand if the user was simply using a wrong password credential and or something more serious. More than likely the person is just using a wrong password but in search of this on my logs, I don't understand why Dovecot doesn't log failed login attempts. When I attempted to login with a wrong password, I show the following in my logs: [root@mail log]# cat /var/log/maillog | grep 'Jan 5' | grep -i 'dovecot' | grep -i 'carlos' Jan 5 11:00:13 mail dovecot: imap-login: Disconnected: user=<carlos>, method=PLAIN, rip=::ffff:192.168.0.10, lip=::ffff:192.168.0.10 Is there a log level or something I am not searching for that will allow me to see failed or invalid logins for Dovecot (IMAP)? Thanks!

[Dovecot] Sorting in IMAP list command?
by Ronald Johnson 06 Jan '10

06 Jan '10

Hi All, I'm running Dovecot 1.2.9 and have noticed the IMAP list command does not appear to send a sorted list of folders with list command. For example on our Cyrus server I get a sorted list of folders (with INBOX listed first): 2 list "" "*" * LIST (\Noinferiors) "/" "INBOX" * LIST (\HasNoChildren) "/" "CalProject" * LIST (\HasNoChildren) "/" "Deleted Messages" * LIST (\HasNoChildren) "/" "Drafts" ... while on our Dovecot server I get seemingly random listing: 2 list "" "*" * LIST (\HasNoChildren) "/" "lsf" * LIST (\HasNoChildren) "/" "mrg" * LIST (\HasNoChildren) "/" "studiosysadmins" * LIST (\HasNoChildren) "/" "Deleted Messages" * LIST (\HasNoChildren) "/" "TriTeam" * LIST (\HasNoChildren) "/" "systemupdates" * LIST (\HasNoChildren) "/" "bb" * LIST (\HasNoChildren) "/" "nagios" * LIST (\HasNoChildren) "/" "server" ... Is this intentional, or have I done something wrong? I didn't see any option in the dovecot.conf to set the behavior of the list output.

[Dovecot] Dovecot quota not working
by Bruno Guimarães Sousa 05 Jan '10

05 Jan '10

Hi everyone, I'm trying to make quota to work in dovecot 1.0.rc15 in a Debian machine. Setting the limit to 1GB and starting to fill up the mailbox and nothing stopped me. It just kept growing and nothing happened. Restarted the service and nothing. I had already exceeded the 1 GB limit and nothing happens, the mailbox still goes bigger and bigger... The *"check_quota"* plugin for squirrelmail shows "0.0% of 1.0GB" in my browser. 1GB is exactly what it is defined in dovecot.conf by maildir. Is it necessary to configure something in postfix?

[Dovecot] imap default separator ignored?
by Harald Dunkel 03 Jan '10

03 Jan '10

Hi folks, I have configured the imap folder separator to '/' (see below). AFAIU the separator character does not affect the internal folder representation managed by Dovecot, but just the communication between client and imap server. Question is: What is supposed to happen if I try to create a folder named "a.b" in this configuration? Since '.' is not a separator character anymore, and since the client doesn't know anything about the internals of Dovecot, I do not see why Dovecot complains about an invalid character? Shouldn't it hide its internal Maildir structure?

[Dovecot] What auth ?
by Spyros Tsiolis 03 Jan '10

03 Jan '10

Hello people, First of all a Happy New Year and best wishes to you all. I've managed to setup dovecot v1.2.9 on a CentOS 5.4 system and I am now, trying to make it auth. I would prefer virtual users and only want to make the IMAP/ IMAPS part work. I don't need POP3 or anything else. The rest will be handled by another SMTP/POP3 application. Now, I almost managed to make dovecot auth a virtual user with his password. However, when it seems it has passed the auth stage (either via IMAP _or_ IMAPS), the command line kicks me out. Here's roughly what I did : 1. Created /etc/dovecot/users and /etc/dovecot/passwd 2. filled in a couple of usernames/passwords encrypted in MD5 format 3. Ran dovecot from command line (service dovecot start [after I created the service ofcourse]) 4. telneted to localhost via port 143 or 993 (with the help of openssl: "openssl s_client -connect the.system.name:993") 5. typed : . login username@fqdn <password> Something worth noticing for step "5". If I do this logging-in with the "user@fqdn" format, the systems kicks me out. I, then, check the latest on "/var/log/dovecot/errors" to find that the system does not complain about the auth. If I do the same logging-in but instead use "user@localhost" (and not the fqdn), the system fails the authentication stage and does _not_ drop me into the shell. Go figure !! Anyway. My question, in essence, is this; Which type of auth should I use ? The manuals (that i've been sinking my head for the last couple of weeks) suggest I should use PAM. PAM, I cannot understand. At the moment, I _think_ I am using MD5. Any pointers here ? I've been reading the /doc/wiki directory for quite some time until it made no sense to me anymore (too much info makes me loose perspective). Any help would be greatly appreciated. TIA, spyros

[Dovecot] disable lazy_expunge for some mailboxes?
by Frank Cusack 03 Jan '10

03 Jan '10

How to disable lazy_expunge for certain mailboxes? My problem is I have a public namespace, whose mail is on a different filesystem than user mails. Some users are allowed to expunge on this shared mailbox, but lazy_expunge is stopping that from working since the mail has to cross a filesystem boundary to make it into the lazy_expunge namespace (location is under the user's home directory). As a workaround can I run a daily cron job to remove messages with the \Deleted flag on them? If so how do I find them? thanks -frank

by Michael 02 Jan '10

02 Jan '10

I would a method for Dovecot to recalculate the quota usage and rewrite it to the quota DB (Called on demand by a non-Dovecot POP3 daemon) I don't want the line deleted in the DB as this would only recalculate next time the Dovecot LDA or IMAP handles a message, and I want to keep the data availability contiguous. Can this be done?

[Dovecot] nested folders
by Jim Pazarena 02 Jan '10

02 Jan '10

using both thunderbird and roundcube with dovecot IMAP, I can create all the folders I desire, but cannot create subfolders; I also cannot delete a folder once created. I get a very un-informative error message from each. Is there a special setting required to permit sub-folder creation? folder deletion? I've got 770 mail:mail virtual_user_home 770 mail:mail mail_sub-directory 770 mail:mail .imap 660 mail:mail .subscriptions 700 mail:mail Drafts 700 mail:mail INBOX 700 mail:mail Junk 700 mail:mail Sent 700 mail:mail Trash Suggestions would be appreciated. Thanks!

[Dovecot] Using Push IMAP to trigger POP3 download
by Aaron Whitehouse 02 Jan '10

02 Jan '10

Hello all, I have an HTPC connected 24/7 to the Internet running Mythbuntu. I also have a web/email host that runs Dovecot for email and provides IMAP and POP3 access. I understand that Dovecot supports Push IMAP and I could, for example, use Thunderbird to connect to my email host to receive instant email as it arrives. I would like to add a Dovecot IMAP server on my HTPC (for increased storage, to aggregate multiple email accounts, to process messages with SpamAssassin and to provide a better webmail interface) and retrieve email from my webhost to my HTPC by POP3. To set up POP3 on my HTPC, I understand that the norm is to set a time interval (say, every 10 minutes) for clearing email. What I would prefer to do, if possible, would be to have Dovecot on my HTPC keep a Push IMAP connection with Dovecot on my webhost. When a new message is available on the webhost, my HTPC would be "pushed" a notification and it could do a POP3 download. This would allow it to clear emails with POP3 (and reduce storage requirements on my webhost), mean that I received emails instantly and not require me to have it poll for messages on a very-regular basis. Does anybody know if this is possible? As an alternative (not solving my space problem on the webhost, but solving the others), is it possible to set up Dovecot to "piggy back" off an existing IMAP server? In my example, my webhost does not offer good spam-checking and webmail. Would it be possible for me to set up a Dovecot server on my HTPC that received messages by Push IMAP, processed them with SpamAssassin (say, moving all of the spam messages to a subfolder) and provided a good web interface, all the while providing updates to the webhost's server? In some ways, this is almost more like an IMAP client than a server. I apologise if these questions are stupid! Happy New Year and thanks in advance, Aaron -- FSF Associate Member: 5632 http://www.fsf.org

[Dovecot] Deliver virtual user's mail to a specific namespace?
by Brian Schang 02 Jan '10

02 Jan '10

Hello: I have virtual users set up for the various mailing lists that I subscribe to. Everything has been working well in both Postfix and Dovecot. Postfix is configured to deliver to a specific mbox file within my mbox mail root. I can access retrieve and read email via Dovecot without any issues. Now I want to make my setup more robust and have these messages delivered to a maildir namespace. I have configured the LDA within the Postfix master.cf file: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient} I have configured the 'dovecot' transport within Postfix in the transport file: test(a)lists.schang.net dovecot: In dovecot.conf I have set up the namespace as follows: namespace private { separator = / prefix = "Lists/" location = maildir:~/MailLists subscriptions = yes } I'm having a hard time specifying the "Lists/" namespace in my userdb passwd-file: test:{PLAIN}linux:2000:200::/home/brian::userdb_mail=maildir:Lists/test I can't get the userdb_mail portion to work. For this user, 'test(a)lists.schang.net', how do I tell Dovecot/deliver to put the message in the 'test' mailbox within the 'Lists/' namespace? I'd appreciate any insight. Thank you. -- Brian Schang

[Dovecot] Issue Authenticating to a new dovecot-postfix installation
by Anthony Nedland 02 Jan '10

02 Jan '10

(Apologies if this is a resend, but I thought I had received a bounceback message.) I have installed dovecot-postfix and postfixadmin on an Ubuntu 9.10 machine. The userdb and passdb are both mysql. If I set up a user in postfixadmin they are able to send. I can successfully telnet into the server remotely by name on 110 and 25. I'm not looking for any authentication encryption/ssl any of that, just POP3/SMTP. When I telnet into 110 I can enter a username with user [username] then when I do pass [password] I get -ERR Authentication failed. I know the user info is correct. When I set up an account in Outlook Express I get "There was a problem logging onto your mail server. Your Password was rejected:" Also saying -ERR Authentication failed.'. (0x800ccc90,0x800ccc92) So basically the same thing. I can attach the tutorial I used in as a .doc if that would help.

[Dovecot] Dovecot LDA with SetUID
by Michael 02 Jan '10

02 Jan '10

Has anyone been able to get Dovecot LDA working where each user has a different UID? All the howtos on the Internet I have found set the UID of a mailbox as fixed for all users. However I have tried to run it on the current SQL database we have (with different UID per user) and I get the following: Jan 1 16:25:40 HOST dovecot: deliver(EMAIL): Fatal: setgid(1000(stdusers)) failed with euid=8(mail), gid=12(mail), egid=12(mail): Operation not permitted I am calling this from Postfix with: dovecot unix - n n - - pipe flags=DRhu user=mail:mail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient}

[Dovecot] Quota with Dict + SQL not updating
by Michael 01 Jan '10

01 Jan '10

Hello all, I have a Dovecot server deployed with a MySQL back end. If the user logs in and there is no quota set for them in table 'quota', the system will automatically inset a line with their username and current messages/storage. However after this it fails to update the information when to reflect new messages coming to their inbox after the original insert of the information. It will only update the information when a user deletes a message. Why is it not updating this information every time their mail is checked with IMAP? Cheers, Michael

[Dovecot] Oracle SQL driver
by Alexander Bukharov 31 Dec '09

31 Dec '09

Hi all. Recently I was looking for an IMAP-server with Oracle support and unfortunatelly I couldn't find one. It was a surprise for me but there is no such functionality at all. So I've chosen an IMAP-server with most flexible and convinient architecture that was Dovecot-1.2.9 and written a driver for Oracle RDBMS support. I used Oracle Pro*C so a Pro*C preprocessor is needed to compile the driver. There is a lot of logging there that should be removed. It would be great if you consider to include this driver to mainstream so Dovecot will be the first IMAP server supporting Oracle as auth backend. All related files are attached. Cheers.

[Dovecot] A Dovecot Sieve spam filter question.
by aja-lists＠tni.org 31 Dec '09

31 Dec '09

Hi, I'd like to make a filtering threshold for users to let them deal with spamassassin spam-level starred < 8 themselves, but spam-level starred higher than 8 should be discarded how can one do that with the "anyof" option ? the following doesn't work with a test email with "gtube", which scores > 999 : # require "fileinto"; if header :matches "X-Spam-Level" "\*\*\*\*\*\*" { fileinto "discard"; } and I think it would be nice to have not so many lines in the globalsieverc file. TIA, Regards, Adrian

[Dovecot] Pigeonhole Sieve IMAP flag question
by Julian Cowley 31 Dec '09

31 Dec '09

Hello, Here is a small script that I've been running to test a problem I've been seeing. Shouldn't this result in the mail being delivered to the inbox as a new message (ie. without the \Seen flag)? require "imap4flags"; addflag "\\Seen"; removeflag "\\Seen"; Every message gets delivered to the inbox as though it's already been read. Using Dovecot 1.2.9 and Pigeonhole Sieve 0.1.14.

[Dovecot] Hostname setting defaults
by Timo Sirainen 30 Dec '09

30 Dec '09

Any thoughts about the following? hostname setting currently defaults to system's host name, without the domain part. It's used (in v2.0): - dovecot-lda (new deliver): If -a parameter isn't specified and there's no Envelope-To: header, the destination address is generated as <username>@<hostname setting> - lda/lmtp: In generated Message-Id: headers ("dovecot-stuff@<hostname>") for rejects, vacation, etc. - lda/lmtp: in reject messages as part of MIME boundary, and also in "Reporting-UA: <hostname>; Dovecot mail delivery agent" header. - lmtp: In the protocol, e.g. "220 <hostname> Dovecot ready" or "421 4.4.2 <hostname> Disconnected for inactivity" - lmtp: In added Received: header Seems pretty clear to me that it should be host.domain.org, not just host. So I suppose I'll change that default. The other thing is postmaster_address. That's accidentally been postmaster(a)example.com in dovecot-example.conf and uncommented. So who knows how many installations have their postmaster address set to that.. I'm thinking of just commenting it out in next v1.2 release so admins needs to change that. But for v2.0 maybe there could be a good default for postmaster_address? "postmaster@<hostname setting>" I think? Because it's postmaster(a)host.domain.org instead of postmaster(a)domain.org, it might not be correct in most installations, but I'm thinking that maybe it's safer. Someone trying out Dovecot on testbox.biguni.edu probably doesn't want bounces going to postmaster(a)biguni.edu..

[Dovecot] dovecot-shared
by Frank Cusack 30 Dec '09

30 Dec '09

I'm confused about dovecot-shared. If the file exists, \SEEN flags are NOT shared? So if dovecot-shared exists, flags are actually private. The doc seems clear on this (albeit not worded very well). I only question it because intuitively you would think the opposite. If backwards compatibility is the reason for this reverse behavior, the file should have been named dovecot-private-flags. In fact that's a great name to stick a list of flags (one-per-line) that are private. -frnak

Re: [Dovecot] Retrieve Physical Message Filename
by Tony Rutherford 30 Dec '09

30 Dec '09

Thanks for the reply. I won't be changing any files, or even accessing them, i'll simply be passing the filename along to "another system". I'm not allowed to change this other system or any of its interfaces. The other system has been in place and is "off limits" as far as changes go (I'm told). To make it simple, this other system needs to be notified of any flag changes on emails. So, when we detect a flag change (in our plugin), we need to pass the message filename along to this other system. I hope this makes sense...and again...i'm not justifying the need for it, but I have to play the hand i'm dealt....Tony RutherfordSoftware EngineerBlueTie Inc.arutherford(a)bluetie.com(585) 586-2000 x1040-----Original Message-----From: "Timo Sirainen" [tss(a)iki.fi]Date: 12/29/2009 04:02 PMTo: "Tony Rutherford" CC: dovecot(a)dovecot.orgSubject: Re: [Dovecot] Retrieve Physical Message FilenameOn Tue, 2009-12-29 at 15:50 -0500, Tony Rutherford wrote: > Hi,Using Dovecot 1.2.9 with Maildir and Layout=FS.In a plugin, i'm > overriding "update_flags":void my_mail_update_flags(struct mail > *_mail, enum modify_type modify_type, enum mail_flags flags)For this > email which is having its flags updated, I need to retrieve the > physical filename of the message.

I've looked around, and I'm guessing > it exists, but I don't see it offhand. The problem is that by the time you're trying to access the file, its flags may have already changed, which also means its filename could have changed. So even if you got it, your code would probably randomly fail. What exactly are you going to do with the filename? Maybe you should instead be opening the file with mail_get_stream() and doing something with the fd. This message is intended solely for the individual(s) to whom it is addressed. If you are not the intended recipient, any dissemination or copying is strictly prohibited. If you believe you received this message in error, please notify the sender and delete from your system.

[Dovecot] Mail storage creation fails with virtual users
by Scott H. W. Snyder 30 Dec '09

So I have recently set up dovecot with a virtual users dovecot.passdb file, but when I attempt to telnet in, it fails because my virtual users don't have proper permissions to create mailboxes.

[Dovecot] Install fails when libdir and libexecdir are the same directory

[Dovecot] multiple attribute templates?
by Mariano Absatz 29 Dec '09

29 Dec '09

Hi, I've been using an attribute template for some time without any problems. My accounts are on an LDAP server and I have an attribute maildropPath which is the maildir path for the user relative to /home/vmail That is, user "mabsatz(a)example.org" has, in attribute maildropPath the string "example.org/mabsatz", meaning that the maildir is in /home/vmail/example.org/mabsatz This is configured like this (taken from http://wiki.dovecot.org/AuthDatabase/LDAP/Userdb) user_attrs = maildropPath=mail=maildir:/home/vmail/%$ pass_attrs = uid=user,userPassword=password,maildropPath=userdb_mail=maildir:/home/vmail/%$ and it works OK. Now I want to start using sieve and, since all accounts are virtual, I want to use a subdirectory "sieve" within the maildir to hold the scripts, so I need (I think) a userdb home to point to the same path... being a monkey I tried to imitate (or rather, extend) the previous configuration like this: user_attrs = maildropPath=mail=maildir:/home/vmail/%$,maildropPath=home=/home/vmail/%$ pass_attrs = uid=user,userPassword=password,maildropPath=userdb_mail=maildir:/home/vmail/%$,maildropPath=userdb_home=/home/vmail/%$ Alas... this didn't work... that is, apparently, the "home" attribute works OK (I got my scripts on the /home/vmail/example.org/mabsatz/sieve directory), but the "mail" attribute got lost and mail is being delivered to /home/vmail/mabsatz. Is there a way to use more than one attribute template AND that both use the same LDAP attribute? Otherwise, can someone think of a better way to do what I'm trying to do?

[Dovecot] Deliver EX_TEMPFAIL's without giving any information
by Denis Khromov 29 Dec '09

29 Dec '09

Hi all. I've had a hard time trying to find out why deliver isn't working after I've updated dovecot from v1.11 to v1.2.8. It just gave me EX_TEMPFAIL without any info in the logs. My deliver was setuid-root. Once I've made a simple shell wrapper script for the deliver executable which saves deliver's stdout+stderr, I've found the reason: /usr/local/libexec/dovecot/deliver must not be both world-executable and setuid-root. This allows root exploits. See http://wiki.dovecot.org/LDA#multipleuids Did a 'chmod o-x deliver' and fixed groups/owners and now everything works as it should. I think this error message should go to log files, not just to stdout/stderr. And it's worth to describe this behaviour in the Wiki. Cheers, Denis

[Dovecot] dovecot -n output of (default) is confusing me
by john.blue＠cox.net 29 Dec '09

29 Dec '09

Hello, I'm new to dovecot and I've been taking my time examining what makes dovecot work. If I have imap and pop3 listed as protocols, dovecot -n outputs: mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 I don't understand why imap is listed twice once as (default), and the other without (default). As a secondary question, why would you want a default of imap as opposed to pop3? Thanks. John

[Dovecot] Log rotation?
by Beto Moreno 29 Dec '09

29 Dec '09

Hi people. I had read dovecot logging info, they say something about using log rotation to help us rotate our log, with this setup: # dovecot SIGUSR1: Re-opens the log files. /var/log/dovecot*.log { missingok notifempty delaycompress sharedscripts postrotate /bin/kill -USR1 `cat /var/run/dovecot/master.pid 2>/dev/null` 2> /dev/null || true endscript } Well, my question is simple, Do we need to restart the service each time logrotation runs? In my case, is wrong this? var/log/dovecot*.log { weekly rotate 8 notifempty missingok copytruncate create 600 root start 0 } I have 2 dovecot logs: dovecot-info.log dovecot.log dovecot-info.log is the biggest, 5MB by week, is to much? Do I have to change our log rotation to "daily"? Centos 5.4 updated, dovecot 1.0.7-7.el5, thanks!!!

[Dovecot] Retrieve Physical Message Filename
by Tony Rutherford 29 Dec '09

29 Dec '09

Hi,Using Dovecot 1.2.9 with Maildir and Layout=FS.In a plugin, i'm overriding "update_flags":void my_mail_update_flags(struct mail *_mail, enum modify_type modify_type, enum mail_flags flags)For this email which is having its flags updated, I need to retrieve the physical filename of the message. I see where using:mail_get_special(_mail, MAIL_FETCH_UIDL_FILE_NAME, &fname);...I can retrieve part of the filename, but without the ":2" and the flags part.Is there a method I can use to get the whole filename (without having to reassemble it myself). I've looked around, and I'm guessing it exists, but I don't see it offhand.Thanks,...Tony RutherfordSoftware EngineerBlueTie Inc.arutherford(a)bluetie.com(585) 586-2000 x1040 This message is intended solely for the individual(s) to whom it is addressed.

[Dovecot] Design: Optimizations for high-latency storage backend
by Timo Sirainen 29 Dec '09

29 Dec '09

Mainly intended for future support of key-value (etc.) databases, but this is probably useful even for regular disk I/O. By using async I/O for disk access, the OS could more intelligently do seeks on disk to read the wanted data with less latency. Problem #1: Accessing message body while searching (e.g. SEARCH BODY). The idea is that searching wouldn't block. Caller would typically use mailbox_search_next_nonblock() function, which can return "try again later" result. Whenever search sees a query that could potentially block (e.g. SEARCH BODY, or searching a header that might not be cached), it goes into a slightly different search mode: - the whole search would typically be run from beginning to end immediately, and the search result state would be stored for each message. - whenever search runs into a situation where the result can't be determined without opening message body, it issues a prefetch command for that message, marks the result for the message as "incomplete", and continues to the next message - once the search is done with all messages, it starts replying to the caller. if the next search result is incomplete at the time, the search returns "try again later". optimizations: - probably there should be prefetch limit (a queue) so that only maybe 10 requests are actually pending at a time. - probably the whole search shouldn't run immediately. maybe it should stop after having 10 requests pending. - prefetch could return only the needed parts of the message, such as "only header" or "only body" (or in future something like "message without attachments") There would be a new call, something like mailbox_search_set_nonblock_callback() that specifies a function to be called when next search result is available. The callback then would continue the search. This is similar to how IMAP SEARCH is already implemented, except currently when mailbox_search_next_nonblock() returns "try again later", Dovecot simply adds a 0 second timeout after which it's called again (that's enough for Dovecot to do some other pending work). Problem #2: Accessing index cache while searching. Cache file is typically in memory or in low-latency disk already. Anyway something similar to #1 could be implemented for it. "Make sure cache x..y bytes in cache file have been read to memory" call or something. Problem #3: Fetching message body (and uncached fields). The nice thing about lib-storage's fetching API is that the caller already specifies what fields it intends to access in mailbox_search_init(). So this code can use a similar technique than searching: - callers only use mailbox_search_next_nonblock() - which keeps returning "try again later" until the message body has been read to memory - trying to access a field that's not specified in wanted_fields in mailbox_search_init() could be (optionally) treated as a programming error and cause a crash instead of a blocking wait. Problem #4: How to drop latencies between IMAP commands? For example a (stupid) client issues commands: a FETCH 1 BODY.PEEK[] a FETCH 2 BODY.PEEK[] ..etc.. You really don't want to a delay between each command. So what Dovecot code needs to happen is to start processing the next command while waiting for previous one to finish reading the body to memory. A lot of this actually already works as intended, but there are some cases that don't, such as FETCH + SELECT (see #5). Problem #5: Opening mailbox index. So if your indexes are also stored in high-latency disk, how do you optimize getting STATUS for each mailbox? Again, a similar idea than before: Create a new mailbox_open_nonblock() function that calls a given callback function when the indexes are read to memory. During the wait it can continue processing more STATUS commands (hopefully client sends them all at once, instead of waiting for each reply before sending next STATUS). .. I think that's all of the problematic cases that could cause blocking. And the solution is always the same: Use prefetching and "try again later" status code with a callback function to be called when it's ready. Luckily there are only two functions that need the above behavior, implementing async callbacks for all functions would have made programming it horrible. The main problem will then be to optimize what and how much to prefetch. For example in the cache file case, should the cache be read to memory when mailbox is opened, or should it be delayed until something is actually wanted to be read from it? Should all of it be read, or should Dovecot attempt to be smarter to reduce memory usage and I/O bandwidth, so e.g. if the cache is wanted to be accessed to 3rd last message, maybe just read the cache file beginning from that message to EOF? Transaction log files have a similar problem. Actually all of this is similar to how Dovecot attempts to cache them to memory when using mmap_disable=yes, so it's not really a new problem.

[Dovecot] Design: Mailbox list indexes
by Timo Sirainen 29 Dec '09

29 Dec '09

I drove over 2000 miles in recent days, so I had some time to think about future Dovecot things. :) Maybe for v2.1 or v3.0, whichever I happen to release next. Here's the first thought: The main idea behind mailbox list indexes was to make getting STATUS information for mailboxes from a single index file. The code was already written for Dovecot v1.1, but it was disabled because of bugs I never got around to fixing. It also was maybe a bit overdesigned to make it fast with thousands of mailboxes. There were two indexes: Mailbox UID -> name map index, and UID -> status info index. I don't think most people have that many mailboxes. Using two index files just makes the common case slower. So the new mailbox list index could be a single index (read/written to using the same index file API as for mails). Index's header would contain an ID -> string map. So basically an array of {uint32_t id, char nul-terminated-name[]} records. Each index record would contain: - mailbox UID number (32 bit) - ID number (32 bit), pointing to a string in the header. That'll be this mailbox's name. - parent mailbox UID (e.g. if parent's name is "foo" and our name is "bar", the mailbox is "foo/bar") - mailbox global UID (128 bit) - mailbox flags (\Noselect, \Nonexistent) - STATUS information: message/unseen counts, last-non-recent-uid (for recent count), uidvalidity, uidnext, highest-modseq - storage backend specific timestamps So typically the whole index would be read into memory and the mailbox tree would be generated based on the parent UID pointers. If there are any \Noselect or \Nonexistent mailboxes, they just have their GUIDs and STATUS info zeroed out. Each time a mailbox is created or renamed, a new name ID is added to the header with the given name. I don't think it's worth it to try to reuse old IDs. Unused names (after delete/rename) will be dropped sometimes later. Whenever STATUS information changes while accessing mailbox, the STATUS info is updated in mailbox list index. Also unless mailbox_list_index_dirty_syncs=yes (or something similar), the index can't be trusted by itself. So before trusting the index, Dovecot needs to check if the index is up to date by comparing the timestamps to what exists in filesystem. For example with Maildir there would be new/ and cur/ directories' mtimes. Then there's the problem of how to notice externally added/deleted/renamed mailboxes. It'll be immediately noticed if such mailbox is tried to be opened, but what about LIST replies? One possibility would be to refresh the list once when session begins and after that just have LIST return indexed mailboxes. Another would be to keep track of directory mtimes and keep stat()ing the dirs to see if something changes. The latter is probably more trouble than worth.. Besides caching LIST and STATUS replies, there's one additional thing I thought of that the mailbox list indexes will be useful for: atomic mailbox list updates. Even if the backend doesn't support e.g. atomic RENAME (such as Maildir++), this can be made practically atomic using the list index. CREATE, RENAME and DELETE commands begin by writing and committing a record to the mailbox list index about the change. Then they'll start the actual change, and finally write to the index that the change is complete. If it crashed in the middle, the next session would finish it. If another session tries to do a conflicting change before the change is finished, it would wait for the previous one to finish. (Probably practically the index would be write-locked and all changes would wait for previous ones to finish.) And the final functionality of this mailbox list index is for the future support of key-value (etc.) databases: The mailbox list index would be the authoritative list of mailboxes. It wouldn't be stored anywhere else.

[Dovecot] checking all folders for new mail (IMAP STATUS command)
by Florian Effenberger 29 Dec '09

29 Dec '09

Hello, I use Thunderbird as IMAP client and do a lot of server-side filtering with Sieve scripts. To be notified of new mails, I want to check all folders (a lot of them...) at once for new mails, and not only the inbox. According to http://kb.mozillazine.org/Checking_for_new_messages_in_other_folders_-_Thun… it should be sufficient to enable one setting -- given that the IMAP server returns the STATUS command correctly. I still run Dovecot 1.0 (from Debian 4.0), and it seems this version doesn't support the IMAP STATUS command, as I have to explictly query each folder with the second mentioned setting. What is the recommended way of checking all folders for new mails? Is there any server-side setting I can activate? Do newer versions of Dovecot support the STATUS command in the way Thunderbird expects it? Or does Dovecot even offer an option like the mentioned IMAP_CHECK_ALL_FOLDERS=1 and IMAP_ENHANCEDIDLE=1 in Courier? Sorry for my maybe dumb question... :-) Thanks, Florian

I am using Dovecot 1.2.9 "dovecot-1.2-sieve-0.1.14" and discarding email seems to work fine. The things I can think of are: 1) Wrong privileges for deleting. What user does procmail / deliver run as? 2) Old Bug in Sieve (http://www.dovecot.org/list/dovecot/2007-July/024290.html) 3) If it fails just sometimes, what is the difference between discarded and nondiscarded mails. If this does not turn up something, I do not have an idea what is going wrong. Only bugfix I then can you provide with, is not to discard but to move those files to a folder 'SPAM' and delete them by hand. Tobi

[Dovecot] Shared mailboxes do not support subfolders

Hi, I'm currently running Dovecot 1.2.8 with dbox mailboxes. I've configured the use of shared mailboxes. I'm able to only see the top-level mailboxes: e.g. Inbox LogWatch Trash Sent but not LogWatch/Server1 LogWatch/Server2 Is this a know limitation of a bug? Rgds, N.

[Dovecot] sieve vs deliver -m
by Frank Cusack 29 Dec '09

29 Dec '09

I'm invoking deliver through postfix with a dovecot transport in master.cf, using the -m ${extension} argument. If I have no sieve script, or a sieve script with an implicit keep, the mail gets correctly filed into the -m mailbox. However if the sieve script has an explicit discard, this gets honored if it doesn't match another sieve action. Shouldn't -m take precedence? I would say that if an extension is present any other sieve action should be ignored, perhaps just sieve_before should be run then the message filed per the extension. -frank

[Dovecot] basic understanding of imap in dovecot
by dovecot＠paz.bz 24 Dec '09

24 Dec '09

I have always used a pop3 daemon, and switching to dovecot has been my introduction to imap. Imap is foreign to me. I am wondering if I am a little off-track here, and would like some clarification. My MTA (exim) delivers email to: /mail/user dovecot, sucks that mail from /mail/user TO /home/user/mail/<filenamesoffolders> dovecot IMAP further uses /home/user/mail/.imap/folders/{.index / .index.cache / .index.log} the mail folder which exim uses doesn't seem to get emptied by dovecot when it sucks the email into /home/user/mail/<filenamesoffolders> when using IMAP. If POP3 is used via dovecot, then it appears that the interaction is directly to the original exim folder and that it does indeed empty (or at least it has the "FOLDER INTERNAL DATA" entry). I suppose my question is, is there a way to have dovecot empty/parse the original exim mailbox so that the customer email isn't sitting in two spots, taking up double the space. This would be in the IMAP environment only, as POP3 seems to be fine. Any online references available to help a newbee understand IMAP? Thanks!

[Dovecot] Permissions errors while reading messages via IMAP
by Geoff Sweet 24 Dec '09

24 Dec '09

Greetings all, I have been trying to setup a new system using Postfix and Dovecot to manage email for a bunch of virtual domains. So far everything is great, and I am now at the point where I am trying to build a webmail interface for the system. I'm using RoundCube for now. The tutorial I have been working from is here: http://workaround.org/articles/ispmail-etch/ Which seems to be a decent enough read. At this point I can login without issue but I can't see any mail messages. When I login, dovecot throws errors like this: Dec 23 12:08:49 mail1 dovecot: auth(default): client out: OK 1 user=geoff.sweet(a)test.com Dec 23 12:08:49 mail1 dovecot: auth(default): master in: REQUEST 1 4312 1 Dec 23 12:08:49 mail1 dovecot: auth(default): master out: USER 1 geoff.sweet(a)test.com uid=5000 gid=5000 home=/home/vmail/test.com/geoff.sweet Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): Effective uid=5000, gid=5000, home=/home/vmail/test.com/geoff.sweet Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): maildir: data=/home/vmail/test.com/geoff.sweet/Maildir Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): maildir++: root=/home/vmail/test.com/geoff.sweet/Maildir, index=, control=, inbox=/home/vmail/test.com/geoff.sweet/Maildir Dec 23 12:08:49 mail1 dovecot: imap-login: Login: user=<geoff.sweet(a)test.com>, method=PLAIN, rip=192.168.20.11, lip=192.168.20.12 Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): Disconnected: Logged out bytes=39/431 Dec 23 12:08:49 mail1 dovecot: auth(default): new auth connection: pid=4315 Dec 23 12:08:49 mail1 dovecot: auth-worker(default): sql(geoff.sweet(a)test.com,192.168.20.11): query: SELECT email as user, password FROM view_mailboxes WHERE email='geoff.sweet(a)test.com'; Dec 23 12:08:49 mail1 dovecot: auth(default): client in: AUTH 1 PLAIN service=imap lip=192.168.20.12 rip=192.168.20.11 lport=143 rport=43878 resp=AGdlb2ZmLnN3ZWV0QHdob290aXMuY29tAGJvYjEyMzQ1 Dec 23 12:08:49 mail1 dovecot: auth(default): client out: OK 1 user=geoff.sweet(a)test.com Dec 23 12:08:49 mail1 dovecot: auth(default): master in: REQUEST 2 4311 1 Dec 23 12:08:49 mail1 dovecot: auth(default): master out: USER 2 geoff.sweet(a)test.com uid=5000 gid=5000 home=/home/vmail/test.com/geoff.sweet Dec 23 12:08:49 mail1 dovecot: imap-login: Login: user=<geoff.sweet(a)test.com>, method=PLAIN, rip=192.168.20.11, lip=192.168.20.12 Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): Effective uid=5000, gid=5000, home=/home/vmail/test.com/geoff.sweet Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): maildir: data=/home/vmail/test.com/geoff.sweet/Maildir Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): maildir++: root=/home/vmail/test.com/geoff.sweet/Maildir, index=, control=, inbox=/home/vmail/test.com/geoff.sweet/Maildir Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): Namespace : Using permissions from /home/vmail/test.com/geoff.sweet/Maildir: mode=0700 gid=-1 Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): open(/home/vmail/test.com/geoff.sweet/Maildir/dovecot.index.log) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +r perm: /home/vmail/test.com/geoff.sweet/Maildir/dovecot.index.log) Dec 23 12:08:49 mail1 dovecot: IMAP(geoff.sweet(a)test.com): open(/home/vmail/test.com/geoff.sweet/Maildir/dovecot-uidlist) failed: Permission denied Dec 23 12:08:49 mail1 last message repeated 2 times There is some permission issue that allows dovecot to deliver email to the /home/vmail location (I dislike this location and want to change it) via the dovecot LDA process, but then not be able to read it when accessed via IMAP.

[Dovecot] imap-login crashes after upgrade to Dovecot 1.2.8 Linux 64-bit
by Chris Wakelin 23 Dec '09

23 Dec '09

Hi all, We moved our Dovecot installation first of all to have all folders and inboxes on NetApps via NFS (with indexes local) then from a physical Solaris 8 4-way UltraSparc server running Dovecot 1.2.5 (32-bit) to a virtualised Ubuntu 8.04 64-bit server with a single virtual processor (in VMWare ESX 3.5) running Dovecot 1.2.8 (64-bit). Since the change, many of our users have experienced random disconnections when proxied in imap-login (either using the internal SSL proxy, or to an external IMAP server) and the error logs contain things like: > Dec 18 00:27:58 imap-login: Info: Disconnected: Connection queue full (auth failed, 1 attempts): user=<user0>, method=PLAIN, rip=<ip0>, lip=134.225.32.156, TLS > Dec 18 00:27:58 imap-login: Panic: file ioloop.c: line 39 (io_add): assertion failed: (fd >= 0) > Dec 18 00:27:58 IMAP 9486 <user1> <ip1> : Info: Connection closed bytes=224/1753 > Dec 18 00:27:58 IMAP 10116 <user2> <ip2> : Info: Connection closed bytes=82/707 ... > Dec 18 00:27:58 IMAP 10296 <user3> <ip3> : Info: Disconnected in IDLE bytes=44/435 > Dec 18 00:27:58 IMAP 10298 <user3> <ip3> : Info: Disconnected in IDLE bytes=263/1662 > Dec 18 00:27:58 dovecot: Error: child 5124 (login) killed with signal 6 (core dumped) (latest ip=<ip0>) > Dec 18 00:27:58 imap-login: Info: Aborted login (no auth attempts): rip=<ip0>, lip=134.225.32.156, TLS: Disconnected and a backtrace gives: > (gdb) bt > #0 0x00007ff1030ad095 in raise () from /lib/libc.so.6 > #1 0x00007ff1030aeaf0 in abort () from /lib/libc.so.6 > #2 0x00000000004112d5 in default_fatal_finish (type=<value optimized out>, status=0) at failures.c:160 > #3 0x0000000000411333 in i_internal_fatal_handler (type=LOG_TYPE_PANIC, status=0, fmt=<value optimized out>, args=<value optimized out>) at failures.c:443 > #4 0x0000000000410996 in i_panic (format=0x6 <Address 0x6 out of bounds>) at failures.c:207 > #5 0x000000000041420e in io_add (fd=-1, condition=IO_READ, callback=0x404db0 <client_input>, context=0x6af000) at ioloop.c:39 > #6 0x00000000004059db in client_auth_failed (client=0x6af000, nodelay=true) at client-authenticate.c:103 > #7 0x0000000000405e07 in client_handle_args (client=0x6af000, args=<value optimized out>, success=true, nodelay_r=0x7fff571009af) > at client-authenticate.c:198 > #8 0x0000000000406214 in sasl_callback (_client=0x6af000, reply=SASL_SERVER_REPLY_SUCCESS, data=0x0, args=0x6361d0) at client-authenticate.c:277 > #9 0x000000000040eb13 in auth_client_input_ok (conn=0x75b6c8, args=<value optimized out>) at auth-server-request.c:196 > #10 0x000000000040dbf3 in auth_client_input (conn=0x75b6c8) at auth-server-connection.c:136 > #11 0x0000000000414aa8 in io_loop_handler_run (ioloop=<value optimized out>) at ioloop-epoll.c:208 > #12 0x0000000000413b9d in io_loop_run (ioloop=0x6552b0) at ioloop.c:335 > #13 0x0000000000408e81 in main (argc=2, argv=0x7fff57100c58, envp=0x7fff57100c70) at main.c:494 Up until this afternoon we had "login_process_per_connection = yes", and login_max_connections at the default (256). This evening I tried with "login_process_per_connection = no" with no problems, except more CPU load and needing to increase login_max_processes_count (and strictly speaking the max fds set with ulimit -n would need to be increased, though I didn't do that as it would have involved killing and restarting the master process - come back Solaris plimit!) Just after midnight, I switched back to "login_process_per_connection = no" and set "login_max_connections = 32" and managed to get core dumps enabled, hence the above! Apart from this problem, the virtual machine has been doing extremely well, so it's not CPU or I/O load related. I'm not sure whether the problem is caused by the switch from Dovecot 1.2.5 to 1.2.8, Solaris to Linux, physical to virtual, or 32-bit to 64-bit! Perhaps we changed too much at once, but it did mean we kept the service going while power was turned off in our main machine room last weekend ...

[Dovecot] expire db(s)?
by ben＠electricembers.net 23 Dec '09

23 Dec '09

with two separate dovecot/backend servers accessing one central mysql server, will it be ok to have them both use the same expires table? Or will that confuse the actual dovecot --exec-mail ext /usr/local/libexec/dovecot/expire-tool.sh cronjob since some of the entries mailboxes won't exist locally? Ben

[Dovecot] qpopper to dovecot migration
by Jernej Porenta 23 Dec '09

23 Dec '09

Heya, We are in the process of migrating from qpopper to dovecot as POP3 server (and IMAP as well) and we hit the UIDL issue with dovecot. Qpopper uses its own algorithm to create UIDL values and if you set it up to write them down in the mbox file as X-UIDL, then dovecot can use them (pop_uidl_reuse = yes). But if you don't use that feature from qpopper, than X-UIDLs are missing and there is no way to create the same UIDL values. So, I was wondering if anyone else hit that issue and maybe knows how to address it (writing an extension or something)? Thanks in advance, regards, Jernej

[Dovecot] Dovecot Deliver CPU usage
by Aravind Divakaran 23 Dec '09

23 Dec '09

Hi All, We have upgraded the dovecot from 1.0 to 1.2.8. After upgradation we have noticed that dovecot deliver process is utilizing a lot of CPU. As a result the mailsystem will stop working. When we limit the no of procs in postfix for dovecot deliver the CPU usage will come down. But we are not facing this problem with the previous version. Below is the log files for dovecot when the error occurs write_full(/home/vmail/dhanbank.co.in/vinukumarvm/temp.server.be3e5a849a909847) failed: No space left on device dovecot: deliver(user(a)example.com): stat(/tmp/Dovecot Delivery Mail) failed: No space left on device But my system has 54gb of free space for root filesystem where tmp residing. Can anyone help me to solve this issue. Rgds, Aravind

[Dovecot] Openbsd Postfix-Dovecot-SASL
by thekat 22 Dec '09

22 Dec '09

Greetings all, I have a OpenBSD /Dovecot server at home running and sending / receiving email "internally" without issue.. Recently, I set up the same at our Parish, but one of our users wants to get their email externally. The user can read their email but has to "send" via the local ISP server.. The problem After much searching I have not found an answer to my question. I would like the user to authenticate to be able to "send" email "through" the server.. OpenBSD uses bsdauth by default in Dovecot. After reading the Postfix http://www.postfix.org/SASL_README.html and the Dovecot Wiki http://wiki.dovecot.org/HowTo/PostfixAndDovecotSASL I have tried multiple configurations but I can't seem to get this to work.. It may be something very simple that I am missing.. All users on the Server have accounts in /etc/passwd (just no shell) Postfix - main.cf mailbox_command = /usr/local/libexec/dovecot/deliver mynetworks = 127.0.0.0/8 smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination dovecot --version 1.1.16 dovecot -n # OS: OpenBSD 4.6 i386 base_dir: /var/dovecot/ protocols: imaps listen: *, [::] ssl_cert_file: /etc/ssl/dovecotcert.pem disable_plaintext_auth: no login_dir: /var/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_user: _dovecot login_max_processes_count: 256 max_mail_processes: 32 mail_location: maildir:~/Maildir mbox_write_locks: fcntl imap_client_workarounds: delay-newmail netscape-eoh tb-extra-mailbox-sep auth default: cache_size: 1024 passdb: driver: bsdauth args: cache_key=%u userdb: driver: passwd socket: type: listen client: path: /var/run/auth-client mode: 432 user: _postfix master: path: /var/run/auth-master mode: 384 user: _postfix Error using bsdauth Dec 21 15:07:09 aml000t3 dovecot: dovecot v1.1.16 starting up Dec 21 15:07:09 aml000t3 dovecot: Panic: auth(default): file passdb.c: line 190 (passdb_init): assertion failed: (passdb->passdb->default_pass_scheme != NULL || passdb->passdb->cache_key == NULL) Dec 21 15:07:09 aml000t3 dovecot: child 18954 (auth) killed with signal 6 (core not dumped) Dec 21 15:07:09 aml000t3 dovecot: Fatal: Auth process died too early - shutting down It looks like bsdauth has a bug and even though this thread "lists" a patch, I haven't been able to find it.. http://old.nabble.com/bsdauth-with-cache_key-failed-ts25800484.html#a258004… so I guess I am looking for an alternative to be able to allow users to "send through the server" Thx for any pointers tk -- View this message in context: http://old.nabble.com/Openbsd-Postfix-Dovecot-SASL-tp26890148p26890148.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Dovecot v2.0 wiki
by Timo Sirainen 21 Dec '09

21 Dec '09

I forked the wiki to http://wiki1.dovecot.org/ is the old docs for v1.x http://wiki2.dovecot.org/ is the new docs for v2.0 For now wiki.dovecot.org points to wiki1, but once v2.0 is released I'll change it to point to wiki2. I symlinked the user directory, so users should stay synced between the wikis. The main reason for wiki2 is to be able to describe Dovecot v2.0's actual behavior everywhere and get rid of all the old v1.x specific settings. The wiki1 is already annoyingly bloated and confusing with information about v1.0 and then v1.1 and maybe even how it's still different in v1.2.. Now would be a good time to do any other larger changes, if anyone has suggestions. :) (Oh, and I haven't yet done any actual changes to wiki2..)

The main disadvantage of this way is executing external aplication on every RCPT TO command. If you'll decide to use perl consider using option perl_at_start to minimize aplication starting time.

[Dovecot] Released Pigeonhole Sieve v0.1.14 and ManageSieve v0.11.10 for Dovecot v1.2.9
by Stephan Bosch 21 Dec '09

21 Dec '09

Hello Dovecot users, Due to personal matters I haven't had time to do anything in the last few weeks. Before that I provided some pre-releases and since nobody indicated problems with those, I release them definitively now. I hope the shit storm has blown over, so that I can dedicate more of my time towards Pigeonhole development. The Sieve release involves a large architectural change, but also fixes quite a few small problems. The ManageSieve release is necessary to match Sieve API changes. Changelog Sieve v0.1.14: * Made the imposed limits on the number of redirects and the number of actions configurable. The settings are called sieve_max_actions and sieve_max_redirects. * Did a major rework of extension handling, making sure that no global state is maintained. This change was triggered by problems that global state info would cause for Dovecot v2.0, but it is also important for v1.2 as it significantly cleans up the library implementation. + Made LDA Sieve plugin recognize the deliver_log_format setting. + Message headers produced from user-supplied data are now RFC2047-encoded if necessary for outgoing messages. This is for example important for the :subject argument of the vacation action. + Added support for the $text$ substitution in the deprecated notify extension. + The subaddress extension now also accepts recipient_delimiter setting as an alias for sieve_subaddress_sep setting. This anticipates the recipient_delimiter setting in v2.0. - Fixed logging of mailbox names. It logged the converted mUTF7 version in stead of the original UTF8 version supplied by the user. - Fixed a minor memory leak in the multiscript support. - Fixed a bug in the recompilation of Sieve scripts. Made sure that scripts are only recompiled when the script file - or the symlink pointing to it - is strictly newer. Changelog ManageSieve v0.11.10: * This release contains adjustments to match changes in the Sieve API. This means that this release will only compile against Pigeonhole Sieve v0.1.14. - Fixed compilation of ManageSieve against CMUSieve. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.14.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.14.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.10.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.10.tar.gz.… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.9-managesieve-0.11.10.diff.… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.9-managesieve-0.11.10.diff.… Refer to http://pigeonhole.dovecot.org for more information. Have fun testing the new releases and don't hesitate to notify me when there are problems. Releases for Dovecot v2.0 are still under development... Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Dovecot vs Exim file locking
by Daniel Campos 21 Dec '09

21 Dec '09

Hi all: We're planning to deploy a large e-mail system storing maildirs in a NAS system through NFS. One of the options we're thinking on is using Dovecot+EXIM. As far as I've read in both project's documentation, both services implement locking allowing multiple servers to access the same maildirs in order to distribute the service load. However, I can't find any information explaining whether both locking mechanisms are compatible, whether any additional configuration is needed both in Dovecot and/or EXIM, or even whether any locking synchronization between both services is needed/recommendable at all. The only remote clue I've found is that, according to Dovecot docs: "Because Dovecot uses its own non-standard locking (dovecot-uidlist.lock dotlock file), other MUAs accessing the maildir don't support it." (but EXIM is not a MUA, anyway) Anyhow theoretically MailDir could even be considered free of locking problems, but I'm not sure of the real implications of putting together several Exim and Dovecot installations pointing to the same NFS filesystem. Any knowledge/experience/link/clue on this would be greatly appreciated. Thanks in advance, Daniel Campos

Hi, i've just upgraded to dovecot-1.2.8 (from 1.2.4) and do now get the following errors when deliver gets hands on mails with some attachments. # tail -n 1 /var/log/messages Dec 14 19:00:36 mail3 dovecot: deliver(user): Panic: file istream.c: line 96 (i_stream_read): assertion failed: (stream->eof) The MTA is postfix running inside a FreeBSD 7.2-STABLE jail. The homes where deliver should put mails are mounted via NFS. As it works with small attachments perhaps this is related to the message size. However i don't get the "stale NFS file handle" error any more which i did under 1.2.4 (See thread that begins with: Message-ID: <20091016122519.GC6309(a)emmi.physik-pool.tu-berlin.de> ) Greetings, Leon

[Dovecot] dovecot: pipe() failed: Too many open files
by JW 19 Dec '09

19 Dec '09

In the past few months we've been having increasing problems with dovecot timing out pop3 logins. As best I can tell it gets to the point where it won't accept any new pop3 logins. The error in the mail log is: dovecot: pipe() failed: Too many open files I've researched this problem a number of times, usually I see suggestions to increase ulimit. I've done this a number of times, all the way up to: ulimit -n 8192 I've put that in the init script right above the daemon start line. So far it hasn't helped. In addition, when looking at lsof, it doesn't seem like we're anywhere near the actual limit. for example, last time dovecot only had 1032 files open. Does anyone have any idea what could be causing the error? Or what else I can try to figure this out? Thank you, JW -- ---------------------- System Administrator - Cedar Creek Software http://www.cedarcreeksoftware.com

[Dovecot] Maildir on NFS - attribute caching question
by Brandon Davidson 18 Dec '09

18 Dec '09

Hi Timo, We've been running Dovecot with Maildir on NFS for quite a while - since back in the 1.0 days I believe. I'm somewhat new here. Anyway... The Wiki article on NFS states that 1.1 and newer will flush attribute caches if necessary with mail_nfs_storage=yes. We're running 1.2.8 with that set, as well as mail_nfs_index=yes, mmap_disable=yes and fsync_disable=no. We have a pool of POP/IMAP and SMTP machines that are accessing the maildirs, and can't guarantee any sort of user session affinity to a particular host. We also mount our NFS shares with 'noac', which is what I'm writing to ask about. I'd like to stop doing that for performance reasons. Do you see any issues with taking that out of the mount options, given our environment? Thanks, -Brad

[Dovecot] lot's of timeouts
by Götz Reinicke - IT-Koordinator 18 Dec '09

18 Dec '09

Hi, since some time ago we do have a lot of "timeouts" connecting to our imap/po3 server. This week I switched the whole system to a new dual quadcore xeon, 24GB RAM, SAS2 RAID-10. (SUN Fire 4170) But the mailclients (mostly thunderbird and apple mail) still reporte the timeouts by accessing the mailboxes. The server is doing smtp, imap/pop3, webmailsystem and spam/antivirus-checking all together. (RH EL 5, sendmail, horde, mysql, mailscanner, spamassassin) We use the original RH dovecot-1.0.7, mbox-format and mailboxes up to 4 GB ... (historicaly grown ...) So where to start debugging the imap/pop3 timeouts? What information may I provide, which doc may I read? Thanks for helping me to find and fix the problem.

[Dovecot] v2.0.beta1 released
by Timo Sirainen 18 Dec '09

18 Dec '09

http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta1.tar.gz http://dovecot.org/releases/2.0/beta/dovecot-2.0.beta1.tar.gz.sig Now that v2.0 is in beta stage I don't expect anything big to change anymore. The configuration and the APIs shouldn't change in non-backwards compatible ways. There are still bugs left to be fixed and some small features to be implemented, but I'd like to have people start testing it more. The biggest unimplemented "feature" is how to convert v1.x configuration easily/automatically to v2.0. Either the old config file should be translated to new one, or Dovecot should be able to read the old config file as-is. I think I like the translation better, so that people won't still be using v1.x configuration when v2.1 arrives and drops v1.x support. Largest changes since alpha3: - if some IP address is failing authentications, all auth attempts from the IP are delayed increasingly. a successful auth drops the delay. max delay is 15 seconds. this is enforced by auth process, so it works across different connections/processes/protocols. - lib-storage plugin API changed. processes handling multiple users now support different plugins for different users. - expire plugin's settings work a bit differently now: http://hg.dovecot.org/dovecot-2.0/rev/46691becc45e - post-login scripting works again, see http://dovecot.org/list/dovecot/2009-December/045139.html - Tons of fixes

[Dovecot] Upgrade 1.0->1.2
by Ivica Glavocic 17 Dec '09

17 Dec '09

Hi all We are planning to upgrade Dovecot from production version 1.0.10 to latest version 1.2.9 Users are using maildir style mailboxes with ~20 GB of messages on SLES10 server. Upgrade will be done by installing new server and then migrating mailboxes from old on new server. Since dovecot-uidlist file have new format and index files have changed in v1.1, what must be done to have new Dovecot v1.2 working properly with old v1.0 maildirs? Thanks, regards Ivica Glavocic

[Dovecot] Filing to public folders

The Dovecot version is 1.2.8 and i am using an LDAP for a user database. The problem is following... i would like to use a quota dictionary backend from file rather than sql proxy for some reasons. Is it possible to get the full path for dovecot-quota file location from LDAP like from mail variable (/mailboxes/storage_01/domain.org/u/us/use/user/dbox/dovecot-quota)? /etc/dovecot/dovecot-ldap.conf user_attrs = storageBase=home,mailMessageStore=mail=dbox:~/%$/dbox/,mailQuota=quota_rule=*:bytes=%$,mailQuotaMessageLimit=quota_rule2=*:messages=%$ Also is it also possible the same for sieve location? I can solve the problem by adding in dovecot.conf sieve = /var/sieve/%Ld/%Ln/dovecot.sieve but i would like to have it all in one place ... t -- View this message in context: http://old.nabble.com/Dovecot-1.2.%2B-tp26803721p26803721.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] v1.2.9 released
by Timo Sirainen 16 Dec '09

16 Dec '09

http://dovecot.org/releases/1.2/dovecot-1.2.9.tar.gz http://dovecot.org/releases/1.2/dovecot-1.2.9.tar.gz.sig Hopefully this release will be enough bug-free that I don't need to make v1.2 releases for next few months. * maildir: When saving, filenames now always contain ,S=<size>. Previously this was done only when quota plugin was loaded. It's required for zlib plugin and may be useful for other things too. + lazy-expunge: Support a single-namespace configuration. If a mailbox is deleted, its messages are merged with its old expunged messages (if there were any). + expire: Settings now support spaces in mailbox names by using quoted strings. - maildir: v1.2.7 and v1.2.8 caused assert-crashes in maildir_uidlist_records_drop_expunges() - maildir_copy_preserve_filename=yes could have caused crashes. - Maildir++ quota: % limits weren't updated when limits were read from maildirsize. - virtual: v1.2.8 didn't fully fix the "lots of mailboxes" bug - virtual: Fixed updating virtual mailbox based on flag changes. - fts-squat: Fixed searching multi-byte characters.

[Dovecot] v2.0.beta1
by Pascal Volk 16 Dec '09

Hi Timo, the imap_client_workarounds are not always parsed. There was on situation, in which cmd->client->set->parsed_workarounds was set to WORKAROUND_TB_EXTRA_MAILBOX_SEP. Sorry, I can't remember what I have done. But when I try to delete a mailbox with Thunderbird imap_client_workarounds are not parsed: (gdb) print cmd->client->set->imap_client_workarounds $7 = 0x1422de0 "tb-extra-mailbox-sep" (gdb) print cmd->client->set->parsed_workarounds $8 = 0 And therefor the command 'x delete box_with_trailing_slash/' fails.

[Dovecot] CRAM-MD5 in Python
by Andre 16 Dec '09

16 Dec '09

Hi to all! I’m writing a python module (python+sqlalchemy) to manage user and domain configuration on my system (I hope to get a CLI tool, a Web app and even a native Mac app, via PyObjc, from my lib). I’m implementing password crypto, but I have some problem in generating CRAM-MD5 password, dovecot style. I’ve found an old discussion on this mailing list and a piece of Perl that works, but I need to implement it in Python; I’ve even read code (hmac-md5.c), but before start hard coding (hard from my POV at least, since I’ve never worked with crypto algorithms in a deep way), is there anyone that have had solved the problem or has any idea on how to approach it? TIA Andre

This may be a stupid question, but here goes. Does the current RPM offered by ATrpms version 1.2.8 come with MySQL enabled? -- --asai
