[Dovecot] SOT: Removing _extra_ linefeeds from MSOutlook(?) messages
by Roderick A. Anderson 24 Aug '09

24 Aug '09

I realize this is sorta off topic but my searches using Google have got me mostly no where. So I thought I'd ask here as there is a lot of _past Postfix_ mail handling issues discussed. The issue is; I have to deal with a lot of messages that come from MS Outlook users and sometimes they are replies to replies to replies ... My reading indicates it has a little to do with HTML composed messages and the format=flowed declaration. This produces messages with *lot* of extra line feeds. Makes the messages nearly unreadable -- in Thunderbird. I'm sure others have got two line (sentence) messages that took 6+ lines to display. Then when they are replies or forwards it is even more. Every line gets two NLs/CRLFs. Anyone have a suggestion of how to _strip_ multiple line feeds from a message? Is there a sieve method/way? I don't want to fiddle with all the users emails just my own. Pointers, ideas, clues? \\||/ Rod --

[Dovecot] critical X-UID reordering problem after upgrade from 1.1 to 1.2
by robh＠cs.indiana.edu 23 Aug '09

23 Aug '09

We upgraded our imap server hardware and went from dovecot 1.1.3 to 1.2.3 in the process and have been having a critical problem since. I believe I've tracked it down to X-UID reordering that dovecot seemed to do to the mbox format (I know, I know...) inboxes. The problem has manifest itself in several ways with different mail clients but the general problem is that the mail clients have gotten confused about which message is which. For example, thunderbird will display the wrong information about a message in the header listing but then show the correct data in the message display window when you actually open the message. As you can imagine, this is causing all kinds of user problems. Here is a very simplified explanation of what I'm seeing. Imagine that the inbox had 5 messages with X-UID values 1, 3, 5, 6, and 9 before the upgrade. After the upgrade the X-UIDs were reordered so these same 5 messages now might have X-UID values of 1, 2, 3, 4, and 5. Thunderbird then shows the summary information like this: Subject/Sender/Date for message 1 Subject/Sender/Date for message 2 Subject/Sender/Date for message 2 Subject/Sender/Date for message 4 Subject/Sender/Date for message 3 Now, if you actually open the 5th message it shows the right message body but the summary information is for the message that *used* to have X-UID 5 (which is now the 3rd message). So, the thunderbird cache is out of sync and I can fix it by removing the .msf file for that mailbox but, as you can imagine, the prospect of getting all the users to remove their .msf/.pst/?? cache files is daunting, to say the least. I've seen discussions about similar things happening with mbox format inboxes but they all seem to be in the context of some ancient 0.xx version of dovecot with known mbox processing bugs. But, I went from a reasonably current 1.1.3 version to 1.2.3. Right after seeing the problem, I upgraded to the just released 1.2.4 but either that didn't address the problem or, if it did, the reordering damage was already done by version 1.2.3. So, my 2 questions are: 1) Anyone know why this would have happened and whether it is a dovecot problem or something I botched? I folded all the local config changes I had made to the 1.1.3 conf file into the stock 1.2.3 conf file so they should have been identical modulo changes in the distro. And, our local config changes are really minimal. 2) Is there anything I can do now other than getting all the users to remove their .msf/.pst/etc files? It sure would be grand if there was something I could do on the server side that would magically cause all the client-side caches to be invalidated. I'm hesitant to strip the inboxes of all the X-IMAPbase and X-UID lines because I'm not sure what the ramifications of that might be. Here are some other random thoughts in case they might be related: - The old server was running 32bit RHEL4 and the new one 64bit RHEL5 - I'm using the pre-built dovecot rpms from atrpms.net - The dovecot index cache is kept in /var/cache/dovecot/indexes and I did not copy that over from the old server to the new assuming it would just be rebuilt. Any and all help is greatly appreciated! --Rob =============== dovecot -n output follows ================== # 1.2.4: /etc/dovecot.conf # OS: Linux 2.6.18-128.4.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.3 (Tikanga) protocols: imaps pop3s ssl: required ssl_cert_file: /etc/mail.pem ssl_key_file: /etc/mail.pem login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_max_processes_count: 512 max_mail_processes: 2048 mail_max_userip_connections(default): 15 mail_max_userip_connections(imap): 15 mail_max_userip_connections(pop3): 10 first_valid_uid: 200 mail_location: mbox:~/mail/:INBOX=/var/spool/mail/%u:INDEX=/var/cache/dovecot/indexes/%u mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 pop3_uidl_format(default): %08Xu%08Xv pop3_uidl_format(imap): %08Xu%08Xv pop3_uidl_format(pop3): %v.%u lda: postmaster_address: postmaster(a)example.com auth default: passdb: driver: pam userdb: driver: passwd

[Dovecot] Released Sieve v0.1.12 and ManageSieve v0.11.9 for Dovecot v1.2.4
by Stephan Bosch 21 Aug '09

21 Aug '09

Hello Dovecot users, I finally managed to make new releases of Sieve and ManageSieve for the recent Dovecot v1.2.4 release. The ManageSieve release is important to match login proxy API changes in Dovecot; older versions will not compile against the new Dovecot release. The new Sieve release first includes the new date extension, which allows matching against date values in header fields and the current date-time at script execution. Changelog Sieve v0.1.12: + Testsuite: added support for testing binaries stored on disk. + Implemented the new date extension. This allows matching against date values in header fields and the current date at the time of script evaluation. Changelog ManageSieve v0.11.9: * Adjusted to changes in the Dovecot login proxy API. This release therefore depends on Dovecot v1.2.4. + Reintroduced ability to abort SASL with "*" response. Latest ManageSieve specification includes it. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.12.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.12.tar.gz.sig ManageSieve (package + patch): http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.9.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-managesieve-0.11.9.tar.gz.s… http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.4-managesieve-0.11.9.diff.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2.4-managesieve-0.11.9.diff.g… Have fun testing the new releases and don't hesitate to notify me when there are problems.

I'm trying to setup deliver as an LDA for system users. I've read http://wiki.dovecot.org/LDA/Sendmail which handles virtual users. I don't see a README for what I need. I want sendmail to accept the mail and then hand off to deliver with sieve plugin. Deliver should look in the users home directory which is found in /etc/passwd for the sieve-script to see what to do with it. If the sieve-script DNE, then just deliver to INBOX(from dovecot.conf). Any help would be appreciated.

[Dovecot] Oops!
by Daniel L. Miller 20 Aug '09

20 Aug '09

I was testing a new webmail client - like an idiot, against my own mailbox, instead of a test mailbox (or even a separate server) - and my Inbox got wiped. Fortunately I backup our mails nightly, so I only lost a couple from today. No idea how the wipe occured - I didn't INTENTIONALLY perform a delete + purge...but it happened. Is there a way of configuring Dovecot to ensure that any delete operation specified by a client results in a "move to Trash" as a precaution? Instead of relying on the client to perform it? -- Daniel

[Dovecot] dovecot/sieve current date
by bart 19 Aug '09

19 Aug '09

Hi, Is there a way in sieve to get the current date, preferably in YYYYMMDD format? To what I've found it's hard to achieve. I have tried including a :global sieve script in which I would set the current date to a certain variable and overwrite this included script every day. But to my disappointement variables set in an included script do not exist in the original script... In fact what I want to achieve is that some actions like forwarding or vacation messages are performed from a certain date untill another date. Which would allow a user to define a timeperiod in which the autoreply or forward should be done and automatically stop without updating the sieve script again. Comparing start and stopdate is cake, but just getting today's date seems to be a hassle, any ideas? regards, bart

[Dovecot] alias does not work
by denis 18 Aug '09

18 Aug '09

Hi, Thank you to everyone who helped me get near the goal. Remains a problem is that aliases don't work. The problem is that in the configuration of alternc, the mails are seen as aliases in the form user_domain.tld. In a second time, a match is made to see if an "real" alias exists. postmap -q test(a)lists.test.net mysql:/etc/postfix/mydomain.cf test-owner_lists.collectifs.net postmap -q test-owner_lists.test.net mysql:/etc/postfix/myalias.cf "| /var/lib/mailman/mail/mailman owner test" With my configuration, this second part doesn't work. Perhaps the simplest is to ask to deliver the mail to user_domain.tld except of user(a)domain.tld in master.cf ? Thanks Denis # main.cf virtual_alias_maps = proxy:mysql:/etc/postfix/myalias.cf, hash:/etc/aliases virtual_mailbox_domains = mysql:/etc/postfix/mydomain.cf virtual_mailbox_maps = proxy:mysql:/etc/postfix/myvirtual.cf virtual_transport = dovecot dovecot_destination_recipient_limit = 1 # master.cf dovecot unix - n n - - pipe flags=DRhu user=www-data:www-data argv=/usr/lib/dovecot/deliver -d $(recipient)

[Dovecot] Gotchas in switching from one server to another without impacting users?
by Gary Chodos 18 Aug '09

18 Aug '09

We have to replace one mail store (foo.example.org) with another (bar.example.org) I rsync'd the maildirs from foo to bar today and the plan is to hold all delivery (in the SMTP server) on foo over the weekend, rsync again (this time it should be much faster since the large xfer already occurred today), then flush the SMTP queue on foo towards bar, direct all new deliveries to bar.example.org. Users currently access their IMAP mailboxes via imap.example.org. I plan to just 'flip the switch' at DNS so imap.example.org points to bar.example.org (instead of foo.example.org) so users don't have to change anything on their end and should not even notice this change. Is there anything else I should think about to mitigate users noticing a change? Does the fact that the mail filenames include 'foo.example.org' in the file name (while new deliveries to bar.example.org will include that new hostname) spell trouble later on or can I ignore it? Is there a more efficient way to achieve my goal? And finally, dovecot on foo.example.org is 1.1.7 while the new server is running 1.1.16. I don't think that should be an issue, but mentioning it just in case. Thanks! -- GC

[Dovecot] Public namespaces with global ACLs 1.2+
by Thomas Leuxner 18 Aug '09

18 Aug '09

Hi, I'm having trouble to get ACLs working in a more restrictive way with namespaces. I would like to grant certain users the ability to create new mailboxes in a public namespace e.g. "Public/Newsletters" etc. It works when I add the users to a ".DEFAULT" ACL file like this: user=username lrwk Anyway I'd like to limit their permissions on the Namespace "Public", or even better - being more restrictive, on "Public/Newsletters". Neither global ACL files for "Public" nor "Newsletters" nested in the global path seem to work. For now only the .DEFAULT ACL (/var/vmail/ domain/etc/acls/.DEFAULT) seems to mitigate the problem which is undesirable. dovecot -n excerpt: plugin: acl: vfile:/var/vmail/%d/etc/acls:cache_secs=300 Thanks Thomas

[Dovecot] BUG: mbox_snarf causes message duplication when two IMAP connections are open
by Robert Lazzurs 17 Aug '09

17 Aug '09

Hello, I have used dovecot to replace an ageing wu-imap installation using the mbox_snarf plugin however I have noticed that when we have more than one client checking the INBOX we then have messages being duplicated in the INBOX. Below is the configuration used as requested in the bug report page. I have confirmed that the duplicates are being caused by dovecot by doing an strace of both processes that have both the INBOX (/mail_home/$username/INBOX) and mail spool file (/var/spool/dovecot/$username) open and delivering a new message through exim to the mail spool file in /var/spool/dovecot/$username. I then see in strace first one process check the spool and copy the message over and then the other processes do the same. If anyone requires any further information to confirm this bug please let me know. Kind regards.

[Dovecot] More Migration Questions
by Richard Hobbs 17 Aug '09

17 Aug '09

Hello, I was on here a month or two ago asking lots of questions about migrating from uw-imapd/qpopper/mbox to dovecot/maildir. I am now at the stage where i'm trying to convert all my emails, but i have a few questions... Where should i convert my mbox mailboxes into? "/home/username/Maildir/" or "/somewhere/maildirs/"? Does it actually matter? Is there a standard location that they *should* go? I've tried converting them into "/somewhere/maildirs/username/", but then i found a dovecot page that says they are usually stored in "/home/username/Maildir" so now i don't know where to put them! Also, having converted the mbox files into maildir files, i do seem to have one email per file, as intended, but the files have names like "1250253965.000586.mbox,S=8167,W=8427:2,S". Should they have the word "mbox" in their filename if they are maildir files? Finally, it appears that our existing IMAP users (all mbox) have mailboxes stored simply in their home directory, not necessarily inside the "~/mail/" directory - is this going to be a problem? The command i'm using to convert is this one: ./migrateuser.sh username /home/username /vol2/maildirs/username This script (and the latest mb2md.py that goes with it, to preserve msg IDs) were obtained from here: http://wiki.dovecot.org/Migration/MailFormat The stage i'm at with the server overall is that uw-imapd and qpopper have been completely removed, exim is currently setup to deliver via it's own method into the mbox files in /var/spool/mail but the exim service is stopped because i'm migrating, and dovecot 1.1 is installed but stopped, and has had no configuration done to it yet whatsoever. So... any advice? Thanks in advance!

[Dovecot] install sieve without any dovecot sources
by Δημήτριος Καραπιπέ ρης 17 Aug '09

17 Aug '09

Hi all I have dovecot 1.1.16 (dovecot-1.1.16-0_94.el5 x86-64) installed on a Red Hat Enterprise v.5. I am already using Dovecot's deliver for virtual users local delivery and need to install the cmusieve plugin for the filtering capabilities. I don't have any sources, since I installed Dovecot from a binary package. Is there any way to install the cmusieve plugin? Thanks in advance Dimitrios Karapiperis

[Dovecot] Crash in v1.2.3: istream.c: assertion failed on line 99
by Phillip Macey 17 Aug '09

17 Aug '09

Hi, I have a couple of people bumping into an issue with their imap process crashing - from the users perspective, their mail client (thunderbird) just stops recieving new mail. It still seems to be possible for them to read their mail using squirell mail. When it crashes, it leaves behind a log message like this on the server: Aug 12 15:52:25 fury dovecot: imap-login: Login: user=<zhi>, method=PLAIN, rip=10.8.5.15, lip=10.10.0.26 Aug 12 15:52:25 fury dovecot: IMAP(zhi): Panic: file istream.c: line 99 (i_stream_read): assertion failed: ((size_t)ret+old_size == _stream->pos - _stream->skip) Aug 12 15:52:25 fury dovecot: IMAP(zhi): Raw backtrace: imap [0x49ddc0] -> imap [0x49de23] -> imap [0x49d4a6] -> imap [0x4a252e] -> imap [0x4a4691] -> imap(i_stream_read+0x48) [0x4a23f8] -> imap(i_stream_read_data+0x28) [0x4a2558] -> imap [0x4ab22e] -> imap(o_stream_send_istream+0x2e) [0x4aa63e] -> imap(maildir_save_continue+0x32) [0x443d12] -> imap(mail_storage_copy+0x6a) [0x462a1a] -> imap(maildir_copy+0x5e) [0x441d2e] -> imap(cmd_copy+0x1fe) [0x41a94e] -> imap(cmd_uid+0x78) [0x41f8d8] -> imap [0x42053c] -> imap [0x4205f2] -> imap(client_handle_input+0x3f) [0x42072f] -> imap(client_input+0x5f) [0x42127f] -> imap(io_loop_handler_run+0xf8) [0x4a5b08] -> imap(io_loop_run+0x1d) [0x4a4c1d] -> imap(main+0x620) [0x428b80] -> /lib64/libc.so.6(__libc_start_main+0xf4) [0x353e41d974] -> imap [0x4198f9] Aug 12 15:52:25 fury dovecot: dovecot: child 14759 (imap) killed with signal 6 (core dumps disabled) I was able to fairly reliably trigger the same behaviour myself by attempting to move a bunch (thousands) of emails in my account using thunderbird - I dont know exactly what it is that triggers the crash though.

I know that login can be disable for system users and groups, but how do I refuse email for system groups? It's a bit of a security/maintenance irritation - I don't want to check for such spam mail, since that is possible. Thanks for any help!! Answer preferably given, so that I can configure it through webmin please.

[Dovecot] can't deliver with Kerberos username
by Nikolay Shopik 16 Aug '09

16 Aug '09

I've been trying to use Kerberos and PLAIN text file for authentication. I've setup deliver in postfix master.cf and make sure correct username are expanded but deliver is always told me "user unknown". I can logon into mailbox using Kerberos w/o problems and can send emails. Looks like Dovecot lookup up passwd files and not finding users which are in Kerberos realm. # 1.0.15: /etc/dovecot/dovecot.conf log_path: /var/log/dovecot.log protocols: imap ssl_cert_file: /etc/postfix/new_chained.crt ssl_key_file: /etc/postfix/mail.pem login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting_capability: yes mail_location: maildir:/var/mail/store/%u dotlock_use_excl: yes maildir_copy_with_hardlinks: yes auth default: mechanisms: PLAIN CRAM-MD5 GSSAPI passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/mail/store/%u socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 438 user: root group: root plugin: sieve: /var/mail/store/%u/sieve

[Dovecot] Listing shared mailboxes with a domainpart
by Mathias Tausig 16 Aug '09

16 Aug '09

Hy! I am currently configuring a new mailserver using postfix and dovecot 1.2.1. The filesystem strucutre in my spool directory is user1/ user2/ domain/info/ domain/office/ user1 and unser2 are ordinary users mailboxes, the latter two contain the virtual mailboxes for info@domain and office@domain as created by postfix. I want these virtual mailboxes (all of them are in maildir format) to be shared to certain real users. I configured a shared namespace: namespace shared { separator = / prefix = shared/%%d/%%n/ location = maildir:/var/spool/vmaildir/%%d/%%n/ #I tried ths as well # prefix = shared/%%u/ # location = maildir:/var/spool/vmaildir/%%u/ hidden = no subscriptions = no list = yes inbox = no } Then I configured a dictionary to list the folders, as described in the wiki: plugin { acl_shared_dict = proxy::acl } dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf } where /etc/dovecot/dovecot-dict-sql.conf holds map { pattern = shared/shared-boxes/user/$to/$from table = virtual_user_shares value_field = dummy fields { from_user = $from to_user = $to } } The database table consists of +-------------+------------+-------+ | from_user | to_user | dummy | +-------------+------------+-------+ | info@domain | user1 | 1 | +-------------+------------+-------+ But when I login as user1 I can neither see nor subscribe to the info@domain mailbox. In the "flat" case (sharing the user2 mailbox to user1), this setup works. I am pretty clueless how to go on. cheers Mathias

[Dovecot] Released Sieve v0.1.10 for Dovecot v1.2.2
by Stephan Bosch 15 Aug '09

15 Aug '09

Hello Dovecot users, In the last week two nasty bugs were found in the new Sieve implementation. Primarily, the include extension did not work when a compiled binary was loaded from disk. This is something that is still not tested by the test suite, giving this bug the opportunity to slip through. Also, the value matching implementation would sometimes cause a assertion failure. Other than that, various small bugs were fixed. On the more positive side, I have implemented support for the new mailbox extension (RFC 5490), which provides the means to test whether a mailbox exists. Also, it adds the :create argument to the fileinto command, which makes sure that the target folder is created before saving is attempted. Of course, this is only useful when deliver is used with the -n option. There wasn't a great need for this extension, but I could use it in the test suite and it was almost trivial to implement. In other news, I have further developed the sieve-filter command line tool. It is getting closer to a usable state, being able to filter a large number of messages in an existing mailbox, but its use is currently still very much discouraged as it tends to be very good at eating mailboxes when the user is less attentive. It needs more command line configuration options, a simulation mode to perform a dry run, and a man page that describes its use and its dangers. Changelog for Sieve v0.1.10: * Changed action execution of fileinto and keep. These changes depend on API additions in Dovecot, making this release depend on Dovecot v1.2.2 or newer. * Further developed the sieve-filter command line tool. This required a few changes to the action execution of the Sieve engine. The tool was successfully tested on folders with a few 100k spam messages. However, the commandline options are still incomplete, a man page is missing and it needs much more testing before I can recommend anyone to use this tool. + Added support for the mailbox extension. This allows checking whether a mailbox exists using the mailboxexists command and it adds the :create argument to the fileinto command to create the mailbox when it is missing. The :create feature is useless unless the Deliver LDA is run with the -n option. + Improved the testsuite with tests for message delivery. Messages stored using keep and fileinto can be fed back into the Sieve engine for verification. This includes testing of applied IMAP flags. + Updated the man pages with the new method of specifying the supported extensions using + and - (for the -x parameter of the sieve tools) + Further developed the deprecated notify extension. A dummy for the denotify command exists, meaning that its use does not cause an error anymore. - Fixed a bug in the derivation of the binary path from the script path. A bare filename would yield a path relative to root. - Fixed a bug in the value matching code. The context data now uses a proper pool in stead of the data stack. Bug reported by Jan Sechser. - Fixed assertion fail in the include extension caused by missing initialization upon binary load. This bug surfaces only for stored binaries. Bug reported by Tom Hendrikx. - Fixed include error message for failed :global include. It mentioned the wrong config parameter. - Fixed broken wiki reference in an error message of the plugin about the 'sieve' setting. - Fixed behavior of fileinto when delivering into a namespace prefix. Previous fix used the wrong storage. The release is available as follows: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.10.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.10.tar.gz.sig Have fun testing the new releases and don't hesitate to notify me when there are problems. Please include your configuration, the involved Sieve scripts and an example message in any bug or problem report when possible, so that I can easily reproduce the issue. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Re: [Dovecot] Redirecting mail gives 'mail forwarding loop' to the sender - calling for sieve help
by Andrés Yacopino 15 Aug '09

15 Aug '09

Yes, the configuration seems odd or interesting as you said. The idea behind this is: - Before scripts will be use for filtering spam, when they have SPAM header. Not problem at it. - User scripts will be used for vacation messages. These are created with Squirrelmail and avelsize plugin (user interaction) - After scripts will be used for doing redirections, such as forwarding mail to a blackberry account(not problem at it) or forwarding to another user account (in the same domain, the problem is here). The reason not to put the redirections or forwarding in users scripts is to avoid users deleting redirections and have in one file all the redirections. I also try to use redirections from avelsieve plugin (0.9.9.9) and it works the forwarding but it didn't work the keep command, the mail is forwarded but the user doesn't have a copy of it. I will investigate your advice for envelope or try to use user's scripts. I didn't know about original headers, if this in RFC sieve documents? Thanks Timo and thanks Stephan for the tips.

[Dovecot] Very long establishment time for secondary connections
by Jeff Mitchell 14 Aug '09

14 Aug '09

Hello, I'm currently on Dovecot 1.1.17 and I have a user that runs into a problem quite a lot. She's using Thunderbird on a Mac. When she sends mail, Thunderbird is set up to save sent mail to her Sent folder. Often (usually when she has not sent another mail for a long while) when she sends mail, Thunderbird sits there saying "Copying message to Sent folder" for about thirty seconds. My best guess, after looking at dovecot messages in syslog related to her login, is that Thunderbird is using a secondary imap process to do this copying and this connection times out due to inactivity, so that when she sends mail it has to reestablish itself. For some reason this reestablishment seems to take a very long time, even though her initial login/connection when she opens Thunderbird is very fast. I looked for a way to increase the inactivity time in dovecot.conf but didn't see one. I don't know of any other user that has this problem, which makes me suspicious of her client rather than Dovecot. Pretty much everyone is using Thunderbird, although she's the only one using it on a Mac. Is it possible/likely that it takes so long because for some reason Thunderbird on a Mac doesn't notice that the second connection has died and is taking a long time trying to use the first invalid connection before reestablishment? Or is it likely that this is a Dovecot problem and I simply haven't figured out what's going on, yet? All help very much appreciated. Thanks, Jeff

[Dovecot] Upgrade question from 1.1 to 1.2
by Wouter van der Schagt 14 Aug '09

14 Aug '09

Good afternoon, I am considering to upgrade from Dovecot 1.1.18 to 1.2.x and was reading your Wiki regarding any changes and found: "If you were using e.g. mail_location = maildir:/var/mail/%h, just change it to mail_location = maildir:%h and add /var/mail/ prefix to home dirs." I am currently using: "mail_location = maildir:~/Maildir" in combination with vpopmail. Does this need to be changed? or is ~/Maildir considered an absolute directory? Is there anything else I should be aware of ? Sincerely, - Wouter van der Schagt

[Dovecot] Dovecot Proxy
by Michel Bulgado 14 Aug '09

14 Aug '09

Hello I have installed Dovecot as a POP3 server, IMAP on my internal network, the authentication against Windows Active Directory. I would like to know how to setup a second server dovecot as my proxy server for external users outside the network, in another segment of different IP addresses, or at least define which mailboxes will be stored on another server to be accessible to both servers. I have reviewed the document on the wiki site, but I said that is only possible with mysql authentication, but as I said the road where the messages are stored, it is possible for NFS? Thanks Michel

[Dovecot] QUOTA not appearing in CAPA
by Tim Traver 14 Aug '09

14 Aug '09

Hi, ok, I've compiled it a few times, and made sure all of my settings are correct, but the QUOTA is not appearing in the opening CAPA that comes with the greeting. I have it configured in the dovecot.conf like so: protocol imap { mail_plugins = quota imap_quota } and I can see when turning debugging on that the following is spit out when starting : Starting DovecotILoading modules from directory: /usr/local/lib/dovecot/imap IModule loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so IModule loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so IEffective uid=65534, gid=65534, home=/tmp IQuota root: name= backend=maildir args= IEffective uid=65534, gid=65534, home=/tmp and then I see the following in the dovecot logs : Aug 10 17:35:10 IMAP(xxxxx(a)simplenet.com): Info: Module loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so Aug 10 17:35:10 IMAP(xxxxx(a)simplenet.com): Info: Module loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so when I log into the IMAP port, I get the following greeting : * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready. So it seems there is no QUOTA support for the IMAP server to query for the quota file... can someone help me as to a direction to go here??? The reason I need it is because I believe the web client relies on the QUOTA being in the CAPA in order to show it... Thanks, Tim.

For those admins who, for whatever ill-advised reason, need to allow users access to external IMAP servers - like AOL - is there a benefit to using Dovecot as a proxy instead of simply having the clients access the external servers directly? -- Daniel

[Dovecot] More effective mailbox fetching over high RTT link
by Andrzej Adam Filip 13 Aug '09

13 Aug '09

Could you offer some suggestion how to fetch mailbox content over high RTT link (with negligible packet loss)? Currently I use IMAP+IDLE *but* it fails to use full available bandwidth due to high RTT and "send command wait for response" nature of POP3 and IMAP4 protocols. -- [pl>en: Andrew] Andrzej Adam Filip : anfi(a)onet.eu Learning without thought is labor lost; thought without learning is perilous. -- Confucius

[Dovecot] sieve: variable extension?
by Lev Serebryakov 13 Aug '09

13 Aug '09

Hello, Dovecot. Does dovecot sieve supports variable extension (rfc5229)? It is very useful for users with large amount of mailing lists, as it allows to write only one rule for all lists (filtering by List-Id). If it is not supported, is here any plans to support it? I can try to implement it, but I don't want to duplicate work, if somebody has this extension in pipeline. -- // Black Lion AKA Lev Serebryakov <lev(a)serebryakov.spb.ru>

[Dovecot] Tilde expansion in ManageSieve for dovecot-1.1.
by Stephen O'Dor 13 Aug '09

13 Aug '09

Greetings all, I'll skip the details of the setup, except to say that it has a non-standard (and non-templateable) home directory path for virtual users. Ran into the following problem when a debian (possibly from backports) packaged dovecot-1.1.2 was upgraded to a dovecot-1.1.13-2~bpo50+1 (definately from backports): sieve-storage: root directory specified by mail data does not exist: ~/Maildir After some analysis, it would appear that ManageSieve (looks like 0.10.4 is included in the debian backports) doesn't do the tilde expansion before doing a stat test to see if the ~/Maildir exists. Here's a quick diff of the change I made to make it work: sodor@madawg:~/tmp/deb-dove/dovecot-1.1-managesieve-0.10.4/src/lib-sievestorage$ diff sieve-storage.c ../../../sieve-storage.c 73c73 < const char *root_dir, *dir, *p, *d; --- > const char *root_dir, *dir, *p, *d, *home; 127a128,133 > /* expand tilde in root so that the stat below works */ > home = getenv("HOME"); > if (home != NULL && *home != '\0') { > root_dir = home_expand_tilde( root_dir, home ); > } > I'm not sure if this was the best way to fix this (or if this is even a bug, I might just have a crazy setup). Thanks, -Steve

[Dovecot] Dovecot proxy server
by michel＠casa.co.cu 13 Aug '09

13 Aug '09

Hello I have installed Dovecot as a POP3 server, IMAP on my internal network, the authentication against Windows Active Directory. I would like to know how to setup a second server dovecot as my proxy server for external users outside the network, in another segment of different IP addresses, or at least define which mailboxes will be stored on another server to be accessible to both servers. I have reviewed the document on the wiki site, but I said that is only possible with mysql authentication, but as I said the road where the messages are stored, it is possible for NFS?

[Dovecot] user_global_* ldap deliver
by Noel Leistad 12 Aug '09

12 Aug '09

Searched archive, but failed to find... :-( "deliver" does not honor user_global_* from dovecot-ldap.conf or userdb static{} also it looks like delivery attempts being made to %n/Maildir/cur ?? one other curious thing, use of ${recipient} in master.cf|deliver command causes the "passdb ldap" lookups to be completely ignored? only checks passdb and ignores userdb compleletely? IF I put noel(at)metc(dot)net into passwd.dovecot using passdb flatfile, auth and delivery seem to work. Thanks for any direction. I lament I couldn't get farther on my own.

[Dovecot] Dovecot Versions and Debian
by Mario Antonio 12 Aug '09

12 Aug '09

If you want to run Dovecot on Debian Lenny for a Production System (with Fast Upgrade System for Security Patches), What would you recommend? Stick to the current port with Dovecot Version 1.0.15 (1:1.0.15-2.3) Use Backports Version 1.1.13 (1:1.1.13-2~bpo50+1) or Use any of the packages from: ---------------------------------------------------------------------------------------------------------------------- Dovecot v1.1 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.1 main Dovecot v1.2 for Debian Testing (binary and source): deb http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main deb-src http://xi.rename-it.nl/debian/ testing-auto/dovecot-1.2 main ---------------------------------------------------------------------------------------------------------------------- Do you find any compelling reason for not using version 1.0.15 ? (Besides of ACL limitations ...) Regards, Mario Antonio

[Dovecot] sieve/managesieve and spam filtering
by Charles Sprickman 11 Aug '09

11 Aug '09

Hello all, I've got a test environment setup in preparation for a move from qmail/vpopmail/courier to postfix/padmin/dovecot. I have a number of questions that seem to span multiple pieces of software, and this is one of them... Our policy with spam filtering is that a user should be able to turn it off (ie: not put tagged spam into a spam folder, but deliver to their inbox) if they want to. Currently qmailadmin and a custom squirrelmail plugin give people the option to do this by dumping a .qmail file in their directory that calls a common maildrop script that will deliver spam to the spam folder. It looks like I can emulate this with sieve and something that can speak to Dovecot's managesieve server. Where I'm stuck is that if I want users to be able to do other custom filtering using sieve, how do I go about making sure that my common spam delivery rule does not get clobbered? This really has me a bit stumped. I see there's a global sieverc that can be included, but I need something along the lines of a per-user include that brings in the spam filtering rule that will "stick" until the user explicitly deletes it. Any ideas? Thanks, Charles ___ Charles Sprickman NetEng/SysAdmin Bway.net - New York's Best Internet - www.bway.net spork(a)bway.net - 212.655.9344
