[Dovecot] Dovecot 1.0rc7 quits without notice
by Chris Laif 22 Aug '06

22 Aug '06

Today I switched one of our servers from Courier (deployed 3-4y ago) to DCrc7. Everything seemed very nice (system load dropped significantly). Unfortunately after some time and ~8000 pop3-logins the main DC loop just quit without _any_ notice. Some pop3-login childs still showed up in the processlist, but the main listener on port 110 was gone. The above described scenario has been observed 2 times. Any suggestions are welcome.

[Dovecot] Filesystem Quota Enhancement Patch
by Scott Alter 22 Aug '06

22 Aug '06

I have just updated my patch that provides enhanced support for filesystem-based quotas in Dovecot. I provides 2 main features: * Support for group quotas * Number of messages quota for users of maildir If both user and group quotas are enabled on the filesystem, the plugin will report the quota that is closer to the maximum independently for both storage space and message count. The message count quota comes from the filesystem inode quota. This patch has been tested on Fedora Core only, but it should work on all other OSes. The only exception is there is no group support on Solaris (I believe this is a limitation of Sun's implementation of filesystem-based quotas). I believe this patch make Dovecot's filesystem-based quota support complete. So, after a little bit of testing, it would be nice to have this merged with the main distribution. Scott Alter

POP3 authentication using virtual user table instead of unix userids - you use the alias email to login with the userid password it is associated to... is it possible?

[Dovecot] messages_count too large errors (1.0RC5)
by Jeff Turner 22 Aug '06

22 Aug '06

Hi, Just today, Thunderbird started throwing errors when accessing a particular mail folder. Looking in the logs showed this: dovecot: Aug 09 15:36:31 Error: IMAP(nmenere): Corrupted index file /imap/mailboxes/nmenere/shared-settings/jira-support/index/.INBOX.Triaged/dovecot.index: messages_count too large (51 > 39) This is a new user's first attempt to access a shared jira-support/ folder, so there is no chance of their index files being corrupt. Deleting the dovecot* files didn't help. Neither did 'cp -rp .INBOX.Triaged .INBOX._Triaged' and then subscribing to the new folder. In fact, the problem seems to be with the files in cur/. There are 51 in total, and 39 of them have an 'i' flag: 1155084961.P27685Q5.redback.sydney.atlassian.com:2,Sbrk 1155084979.P27685Q6.redback.sydney.atlassian.com:2,Sbtk 1155085103.P27685Q10.redback.sydney.atlassian.com:2,Sbwk 1155085175.P28321Q1.redback.sydney.atlassian.com:2,Sbcki 1155085221.P27685Q12.redback.sydney.atlassian.com:2,Sbwk 1155085228.P28321Q4.redback.sydney.atlassian.com:2,Sbki 1155085231.P28321Q5.redback.sydney.atlassian.com:2,Sbki 1155085246.P28321Q6.redback.sydney.atlassian.com:2,Sbki Loading the maildir in mutt and re-saving them all to a clean maildir fixes the problem, by resetting the flags. Going through the logs, I see other users hitting this problem with other mailboxes. Anyone know what 'i' means? I guess it's a dovecot extension? I should mention that this happened a few months ago too, with 1.0b8 (I think). This is all running on a linux box, mail delivered with procmail, no special settings. Anyone seen this before? Cheers, Jeff

[Dovecot] Dovecot authorisation problem
by Phil Clare 21 Aug '06

21 Aug '06

Hi List, I am trying to set up dovecot on my mail server and am having some difficulties… I want to use virtual mailboxes and so have set up a passwd-file for userdb and passdb and created entries for a user but they don’t seem to be working… I have included the relevant lines from all three files below… Dovecot.conf… auth_userdb = passwd-file /etc/dovecot/users auth_passdb = passwd-file /etc/dovecot/passwd users file… HYPERLINK "mailto:phil@topazaccommodation.co.uk::503:503::/var/mail/vhosts/topazaccomm odation.co.uk:/bin/false"phil@topazaccommodation.co.uk::503:503::/var/mail/v hosts/topazaccommodation.co.uk:/bin/false:: passwd file… phil@topazaccommocation.co.uk:$1$G/FqlOG5$Vj0xmc9fKY.UVr8OWr/7C1 As far as I know the password is the word ‘test’ encrypted with MD5 (is there anyway to have these as plain text?) Finally the entry from the log file… Aug 18 16:51:58 95304-web1 dovecot-auth: passwd-file(phil(a)topazaccommodation.co.uk): unknown user Any ideas?

[Dovecot] dovecot vs qpopper performance testing results
by asko 21 Aug '06

21 Aug '06

Hi, I did some performance testing with dovecot and qpopper, if anyone is interested.. Hardware: Dual Xeon 2.8 with HT enabled (dmesg sees 4 cpu-s), 1 GB RAM, SCSI RAID 1 with 2x Maxtor Atlas 10K V disks. Software: CentOS 4.3, Qpopper 4.08 in standalone mode vs Dovecot 1.0-0_19.rc6, ext3 filesystem Mailbox format Mbox, tested Pop3 with PAM authentication My setup had 15 test users with 15 identical 40 MB mbox files. Each mbox had 370 messages, 35 % of them had attachments. So average message size is about 110 KB, average attachment size 220 KB. "rabid" utility is part of postal package (http://www.coker.com.au/postal/) Command line, which fetches and deletes all the messages from users in the textfile: rabid -p 1 192.168.x.x ./users - Resulting fields are: time,messages,data(K),errors,connections,SSL connections,IMAP connections Results (only the best one shown): Qpopper: 1 parallel processes: 12:36,1020,111470,0,6,0,0 5 parallel clients: 12:44,3246,366207,0,13,0,0 15 parallel clients: 13:06,4099,481347,0,48,0,0 Dovecot: p1: 12:19,3316,367859,0,13,0,0 p5: 12:50,4653,524456,0,34,0,0 p15: 12:56,5063,578889,0,84,0,0 As you can see, Dovecot is faster.. With 15 parallel processes it seems to have saturated my 100Mbit/s LAN (578889 kB data in one minute). Dovecot had noticeably smaller disk IO and system load was smaller too, probably thanks to smaller IO. Qpopper performed better than I hoped.. It is probably due fast disks of the test system, I wouldn't expect such numbers using single IDE disk. Conclusion: The hardware was too fast for testing, LAN became a bottleneck atleast once. The results could be different with different mbox structure.. Anyway, I was convinced, Dovecot wins. -- asko
