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

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

[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? I had to use (at least in the past): sv d /var/service/dovecot killall dovecot killall -9 imap-login ps auxwww|grep dovecot to make sure everything would be dead... -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de

[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

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.

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?

[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 * * * *************************************************************************
