[Dovecot] Old Thunderbird problem - need a fix
by Marc Perkel 28 Jan '09

28 Jan '09

I've been having a Dovecot/Thunderbird problem for about a year now and I need a fix. When I restart dovecot everything is fine but as the day progresses thing start deteriorating. When I empty my trash folder it doesn't empty. I get an indication that email has arrived in my inbox by the unread message count but can't access it. Messages arrive by appear to be empty. Folders that should be empty still have message counts showing. With all of the above problems - restarting dovecot make them all go away. I am doing something unusual in that I use Exim to directly deliver (maildir) to the inbox and other folders. And I have processes that take email out of certain folders (spam learning). Whatever the problem is I think that when I restart Dovecot I'm forcing Thunderbird to reconnect. Perhaps the solution is to somehow force Thunderbird to have to reconnect every time rather than have a persistent connection? Looking for suggestions. Thanks in advance.

[Dovecot] Store sent email
by pierre.casenove＠almerys.com 28 Jan '09

28 Jan '09

Hello all, I've set up a webmail solution based on RedHat EL 5, sendmail, spamassassin, clamAV and dovecot by following this tutorial: http://www.redhat.com/magazine/025nov06/features/email/index.html I have configured everything without any problem, I can send and receive emails, using Maildir store format. Now, what I don't know how to set up: I would like to store the emails sent by the users in a dedicated store (Like Sent Emails in many webmails).... and I've got no idea on how to do this! By googling a little, I found this thread ( http://www.dovecot.org/list/dovecot/2007-April/021447.html) where a plugin is mentionned. Has it been developped or is there another solution? I'm using dovecot 1.0.7, shipped with RHEL 5 distribution. I am really discovering all the products around the email so I'm a bit confused. Thanks a lot for your answer, Pierre

[Dovecot] imap flags - \* - dovecot 1.1.{8,9}
by Arkadiusz Miskiewicz 27 Jan '09

27 Jan '09

Isn't \* supposed to be (almost always) in flags after "SELECT" command in dovecot imap? Isn't \* meaning is "you can store any new flag" ? 20 select INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft)] Flags permitted. so no \* ... [..] 50 store 1 +flags $MDNSent * FLAGS (\Answered \Flagged \Deleted \Seen \Draft $MDNSent) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft $MDNSent)] Flags permitted. * 1 FETCH (FLAGS ($MDNSent)) 50 OK Store completed. 60 logout * BYE Logging out 60 OK Logout completed.

[Dovecot] dotlock timestamp trouble
by Giorgenes Gelatti 27 Jan '09

27 Jan '09

Hi there, I'm getting a lot of this message in production log: Created dotlock file's timestamp is different than current time (1232468644 vs 1232468524): /path/to/dovecot.index.log The IT guy swears the clocks are sincronized. Whe even have made a test in the machine running dovecot, inside the user's mailbox: # > foo; ls -l --time-style=full-iso foo; date -rw-r--r-- 1 root root 0 2009-01-19 17:40:55.000850000 +0000 foo Mon Jan 19 17:40:55 UTC 2009 The timestamps seems to match. I'm using dovecot 1.1.6 over NFS. Any thoughts? Thanks in advance, gpg

[Dovecot] No Spaces in Directory names
by Matt Rude 27 Jan '09

27 Jan '09

How can I make it so my users can not create folders with spaces in them? Or allow them to create such folders but rewrite them on the hardrive with a "_" or some other symbol. I have looked threw the wiki but couldn't find anything about folder name restrictions or folder name rewriting (rewrite the space to a "_"). Im having problems with some of the expire and compress scripts when it hits these types of folders. Is dovecot able to restrict or rewrite the names of imap folders? dovecot -n # 1.1.9: /usr/local/etc/dovecot.conf # OS: Linux 2.6.27.9-159.fc10.i686 i686 Fedora release 10 (Cambridge) ext3 listen: *:143 ssl_listen: *:993 ssl_cert_file: /etc/postfix/SSL/mail.mattrude.com.cert ssl_key_file: /etc/postfix/SSL/mail.mattrude.com.key login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login login_user: postfix mail_location: maildir:/var/spool/virtualmailboxes/%d/%u/imap/:INBOX=/var/spool/virtualmailboxes/%d/%u/ mail_plugins: quota imap_quota zlib auth default: mechanisms: plain login cram-md5 cache_size: 128 cache_ttl: 600 master_user_separator: * passdb: driver: sql args: /etc/dovecot-mysql.conf passdb: driver: sql args: /etc/dovecot-sql-master.conf pass: yes master: yes userdb: driver: sql args: /etc/dovecot-mysql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: virtualmail group: virtualmail plugin: sieve: /var/spool/virtualmailboxes/%d/%u/dovecot.sieve sieve_storage: = /var/spool/virtualmailboxes/%d/%u/ quota: maildir quota_rule: *:storage=10M quota_rule2: Trash:storage=20% Thanks -Matt

[Dovecot] Dovecot discards mail over quota
by Gary V 27 Jan '09

27 Jan '09

I'm new to Dovecot, using 1.1.8 and I just wanted to verify that what I am observing is the intended behavior. I'm using Maildir++ quota. When a message is delivered to a mailbox that cannot accept the message because it would place them over the quota limit, deliver states to the MTA that the messsage was delivered successfully (example using postfix): Jan 17 12:05:31 msa postfix/pipe[13983]: 088C5B9D47: to=<test(a)example.com>, relay=dovecot, delay=0.72, delays=0.34/0.02/0/0.36, dsn=2.0.0, status=sent (delivered via dovecot service) But in actuality the mail is discarded (dropped). Then a bounce is created stating the mail was rejected: Your message to <test(a)example.com> was automatically rejected: Quota exceeded (mailbox for user is full). Question: is it possible (without changing code) to alter this to where deliver would instead tempfail or something. Somehow it seems wrong to me to tell the MTA that everything is good, and then silently discard messages - regardless of the fact dovecot creates a bounce. This is not necessarily ideal either, but I _am_ wondering if this is configurable or not. deliver(test(a)example.com): 2009-01-17 12:05:31 Info: msgid=<1293474859.20090117120812(a)example.com>: save failed to INBOX: Quota exceeded (mailbox for user is full) deliver(test(a)example.com): 2009-01-17 12:05:31 Info: sieve runtime error: Keep: Generic Error deliver(test(a)example.com): 2009-01-17 12:05:31 Error: sieve_execute_bytecode(/var/sieve/global.sievec) failed deliver(test(a)example.com): 2009-01-17 12:05:31 Info: msgid=<1293474859.20090117120812(a)example.com>: rejected: Quota exceeded (mailbox for user is full) deliver(garyv(a)example.com): 2009-01-17 12:05:31 Info: msgid=<dovecot-1232219131-401523-0@msa>: saved mail to INBOX -- Gary V

[Dovecot] behavior of dovecot with Openldap
by Masaharu Kawada 27 Jan '09

27 Jan '09

Dear team, I'm sorry if this is a stupid question, but I'd like to know the behavior of dovecot in a particular stuation. My questions are as follows. In /etc/dovecot-ldap.conf, 'hosts=' field is the one which can be used to specify availabled ldap server to access from the clients to authorize. And also sevral ldap servers can be specified in 'hosts =' field as shown like below. hosts = ldap-server1.example.com ldap-server2.example.com ※both server have the same configuration and available to replication ldap-server1(master) to ldap-server2(slave). If this is right, how does dovecot know which ldap server is currently used? and if the master dies, how does dovecot know and switch to slave one? In addition, which one is the exact behavior of dovecot in case master server dies? 1. only swithcing to the slave server 2. switching to the slave server, and once the master server is reactive then switch back to the master server automatically OS：RHEL4 U3 kernel 2.6.9-34.ELsmp openldap-2.2.13-12.el4 Thanks in advance, Masaharu Kawada ------------------- Masaharu Kawada Associate Global Support Engineer Red Hat K K Ebisu Neonato 8F 1-18 Ebisu 4-chome, Shibuya-ku Tokyo 150-0013, Japan Direct: +81-3-5798-8482

[Dovecot] FOLDER INTERNAL DATA (uw pine header)
by Charles Gregory 26 Jan '09

26 Jan '09

Hello! I run Dovecot on CentOS 4 (dovecot-1.1.4-0_81.el4), and I *also* run the "Alpine" mail system that comes with that OS. Alpine still writes out the 'FOLDER INTERNAL DATA' pseudo-message at the beginning of each user's mbox, but dovecot does not. I make use of that record as a simle/quick way to verify when a user actually last read their e-mail (for administrative purposes, identifying stale/unused accounts), so is there any way to configure/command dovecot to write (or update) these hidden messages? (Note: I tried looking in the archives, but most references seemed to be about this message being a 'side effect' of transferring *from* UW IMAP, and how to get 'rid' of it. Not what I need. :) Apologies if this was covered before in a different thread.) - Charles

[Dovecot] uint_cmp bug
by Mike Abbott 26 Jan '09

26 Jan '09

In reviewing the differences between 1.1.8 and 1.1.9 I saw a probable bug in the new function uint_cmp() in src/lib-storage/index/maildir/ maildir-sync-index.c: if (*i1 < *i2) return -1; else if (*i1 > *i2) return -1; else return 0; The second case should return 1 not -1.
