I'm trying to use dovecot-deliver with sieve plugin, delivering to Maildirs. Everything seems working O.K., but I'm getting the following lines in /var/log/maillog: --- Mar 29 00:06:00 alt64 dovecot: imap-login: Login: user=<seriv>, method=PLAIN, rip=66.80.117.2, lip=192.168.10.8, TLS Mar 29 00:06:00 alt64 dovecot: IMAP(seriv): mmap() failed with index file /home/seriv/.imap/dovecot.index: No such device ...

[Dovecot] can't receive mail from other hosts
by carpenter＠strongs.org 29 Mar '07

29 Mar '07

i'm running RHEL v 5 and 1.0-1.2.rc15 of dovecot and 2.3.3-2 of postfix. users can send mail to outside hosts, but can not receive them. i find no errors in the maillog -- i used a page from the redhat docs to configure postfix and dovecot so that they used the same mail directory... i think... any ideas on how to debug and/or fix this would be greatly appreciated. thanks, steve

[Dovecot] assertion failed (1.0-rc27)

Under Dovecot 1.0-rc27 on Solaris 10 we noticed this error today affecting one of our users repeatedly: Mar 28 14:02:01 myhost dovecot: IMAP(myuser): file mbox-sync-rewrite.c: line 423 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) Mar 28 14:02:01 myhost dovecot: IMAP(myuser): Raw backtrace: 0x7ac54 -> 0x42cd4 -> 0x3e968 -> 0x3f54c -> 0x3f980 -> 0x6c834 -> 0x298a0 -> 0x2114c -> 0x212e8 -> 0x22d60 -> 0x22cd8 -> 0x22ed8 -> 0x81004 -> 0x808d8 -> 0x2b3f8 -> 0x1db5c Mar 28 14:02:01 myhost dovecot: child 24818 (imap) killed with signal 6 I have no idea what the user experienced, as we simply noticed this in the logs (which appear on our consoles, too). I hope this is enough information, as we do not run with core dumps enabled on our production servers. -- Steven F.

[Dovecot] New mail not appearing consistently in Outlook 2003
by Karl von Randow 29 Mar '07

29 Mar '07

Hi all, I have continuously experienced a new mail not appearing problem in Outlook 2003 on Windows XP. Using Dovecot 0.99.14 on Debian Sarge and now in 1.0rc26 and rc27. The problem exhibits itself as: Some new mail is randomly(?) not shown in my mailbox. More new mail does appear, so it's difficult to know when a message has been missed. If I restart Outlook the missed new messages will appear as unread in the order where they should have been received in my inbox. I use secure imap. I get email through my inbox (receipts from a website we're testing, at its peak maybe 2-3 a minute) that are moved into another mailbox using a rule in Outlook. These are often the messages that are missed as above, but it often includes other email as well. The mail box format is mbox on the server. The mail delivery is by exim4 from Debian Sarge. I wondered if there was a locking problem between exim4 and dovecot? My transport in exim4 for delivering the mail is: mail_spool_home: debug_print = "T: appendfile for $local_part@$domain" driver = appendfile file = /home/vmail/$domain/$local_part/INBOX delivery_date_add envelope_to_add return_path_add group = mail mode = 0660 mode_fail_narrower = false The problem is reproducable in that I see the problem occur everyday. I am about to compile and install rc28 to see if that improves matters. I'd appreciate any help resolving the problem! Here is my dovecot.conf: # /usr/local/etc/dovecot.conf protocols: pop3 imap imaps disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_extra_groups: mail mail_location: mbox:/home/vmail/%d/%n/mail/:INBOX=/home/vmail/%d/%n/INBOX mbox_dirty_syncs: no mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: passwd-file args: /etc/vmail.passwd userdb: driver: static args: uid=1064 gid=1001 home=/home/vmail/%d/%u

[Dovecot] Bug-report for rc28: Mailbox isn't a valid mbox file
by Erik van Oosten 29 Mar '07

29 Mar '07

Hi, When I try to open the attached mbox file I get the following warning in Thunderbird 1.5.0.10: 'The current command failed. The e-mail server responded: Mailbox isn't a valid mbox file'. I also tried this with squirrelmail, with the same result. The Dovecot version is dovecot-1.0.rc28, compiled from source. The attached mbox was correctly read from, and written to in earlier versions (either rc15 or rc22, I am not sure). The initial import was done (a long time ago) by copying a file from my Thunderbird profile directory. OS: SuSE 10.0, x86 Filesystem: ext3, (no NFS) Output of dovecot -n: ------------------------------------ # /usr/local/etc/dovecot.conf disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u auth default: passdb: driver: pam userdb: driver: passwd ------------------------------------- Can I somehow recover the data in this mbox? Regards, Erik. -- Erik van Oosten http://day-to-day-stuff.blogspot.com/

[Dovecot] odd behavior with Dovecot LDA
by Steven F Siirila 29 Mar '07

29 Mar '07

Okay, to convince myself that quota handling was working okay with Dovecot 1.0-rc27 on Solaris 10, I tested sending a message to an account that was purposely over-quota. The account in question had a vacation message set up. For the first test, there was no $HOME/.imap directory at all. I received the vacation message, but the message which was supposed to be delivered locally queued in Postfix (temporary failure). For the second test, I created $HOME/.imap and $HOME/.imap/INBOX directories with the owner and group set to that of the user (just to make sure the code handled things the same). Again, I received the vacation message, but the message which was supposed to be delivered locally bounced back to me after Dovecot LDA crashed: <syst0005(a)peridot.tc.umn.edu>: Command died with status 139: "/opt/dovecot/libexec/dovecot/deliver -f "$SENDER"". Command output: Segmentation Fault It appears that Dovecot LDA assumes that if .imap/FOLDERNAME exists that the index files must also exist.. I wonder what other assumptions might cause segfaults. -- Steven F.

[Dovecot] How do I check the release #?
by Randolph Kahle 29 Mar '07

29 Mar '07

I am a dovecot newbie and I am setting up a machine that already has dovecot installed. Since bugs are being resolved rapidly, it appears that I need to know the release version of dovecot I am running. Is there a command I can issue or a file I can examine to determine the release version of my installation? -- Randy

[Dovecot] transfer files from Plesk qmail to Dovecot and Postfix
by Frank Church 29 Mar '07

29 Mar '07

I have some files I want to transfer from Plesk qmail to Postfix with virtual mailboxes, MySQL, Maildir etc. I can add the accounts to the database manually as there are only a few of them. In the case of the mail folders, is it merely a matter of copying the mail files over, or are there some adjustments to be made to the files? I have noticed the thread about the Courier to Dovecot script and I wonder whether it may have a role in this process.

[Dovecot] auth server refusing connections intermittently
by Steven F Siirila 28 Mar '07

28 Mar '07

Running Dovecot 1.0-rc27 on Solaris 10.. We have been noticing intermittent messages of this sort and wondered if this indicates whether we need to add more dovecot-auth worker processes: Mar 28 03:15:41 myhost dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 28 08:10:20 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 09:08:13 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:23:38 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:35:37 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 10:50:59 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 12:00:44 myhost dovecot: pop3-login: Can't connect to auth server at default: Connection refused Mar 28 12:07:31 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused Mar 28 14:44:57 myhost dovecot: imap-login: Can't connect to auth server at default: Connection refused However, this system has over 7,000 users and 1,500 simultaneous IMAP and POP3 connections, and we only see one dovecot-auth process running. By contrast, another server has over 11,000 users and 3,000 simultaneous IMAP and POP3 connections (but is currently running rc24), and we only have seen 3 of the above error messages there -- and there is only one dovecot-auth process there as well. Does this sound right? Also, how many times are these connections retried (and at what sleep interval, if any) before it gives up? -- Steven F.
