[Dovecot] dovecot report W value error and Corrupted index cache file
by 甄东宇 14 May '12

Hello everybody, I have a problem and no idea. Yesterday Dovecot.log report: Warning: Fixed a duplicate: /opt/*/cur/<time>.M*.<domain>,S=*,W=*:2,S -> <time>.M*.<domain> Now Dovecot.log report: Error: FETCH [ ] for mailbox INBOX UID 10546 got too little data: 79850 vs 81231 Error: Maildir filename has wrong W value: /opt/DIR/DOMAIN/USER/cur/1281317869.M*.*,S=79569,W=81231:2,S~ Error: Corrupted index cache file /opt/DIR/DOMAIN/USER/dovecot.index.cache: Broken virtual size for mail UID 10546 A few days ago, we used a new machine for mail server (and we used maildir format with dovecot-1.2.0).In fact ,we used iRedmail on CentOS5. And last week, I copy some mail data from old machine to new one through SCP and CP command. It worked well. Yesterday, I copy the mail data from old machine to new one through RSYNC. I guess maybe the errors have a relationship with rsync, because the new machine open SELinux and the rsync data error. Although the files were copyed to /cur directory , it seemed to appear the same mail file. Now,I receive some BLANK mails by pop3 of OutLook2007 . There are not any Header and any Body( Totally BLANK). Outlook show they are 760B size. I am confusing for this problem. Please help me. Thank you.

[Dovecot] userdb namespace settings bug
by Alexander 'Leo' Bergolth 14 May '12

14 May '12

Hi! Since upgrading to 2.1.6, setting namespaces via environment variables using a imap-postlogin-script *sometimes* doesn't work. Sometimes, the prefix of a namespace isn't set correctly, but is set to an empty string, which leads to the following error: namespace configuration error: Duplicate namespace prefix: "" However, the environment is set correctly, the error seems to occur when parsing the environment. See the attached log: The postlogin-script sets the environment variables attached as dovecot-postlogin-environment.txt. (dumped from postlogin script via env) However, the variable "NAMESPACE/S-GSD/PREFIX=Shared/GSD/" gets parsed as: plugin/namespace/s-gsd/prefix=Shared/GSD/ See the error message: Unknown userdb setting: plugin/namespace/s-gsd/prefix=Shared/GSD/ After restarting dovecot, the same configuration sometimes works correctly. I'd greatly appreciate your help! Unfortunately I have done the upgrade on a production system, so the issue is quite serious for me.. Will downgrading to 2.0 work? (Index-files, etc?) Thanks, --leo -- e-mail ::: Leo.Bergolth (at) wu.ac.at fax ::: +43-1-31336-906050 location ::: IT-Services | Vienna University of Economics | Austria

[Dovecot] dovecot wants to access my music directory
by Ian Pilcher 14 May '12

14 May '12

I am getting an SELinux error every time dovecot starts, because it is trying to access my music directory (/srv/music). I've read the doveadm-mount man page, and tried: doveadm mount add /srv/music ignore but it didn't make any difference. Now, I certainly didn't tell dovecot to access this directory, so how can I tell it *not* to do so. This is dovecot-2.1.6-2.fc17.x86_64 on Fedora 17 Beta, BTW. Thanks! -- ======================================================================== Ian Pilcher arequipeno(a)gmail.com "If you're going to shift my paradigm ... at least buy me dinner first." ========================================================================

[Dovecot] dovecot-2.1.6: why are loglines longer and longer
by Reindl Harald 13 May '12

13 May '12

do we really need "session=<ugAua+i/ewBUcit1>" additional to proxy log-lines? until this change it was possible on a 24" screen with "tail -f /var/log/maillog" to watch without linebreaks, now each proxy line breaks PLEASE reconsider such changes! May 13 12:27:38 mail dovecot: imap-login: proxy(*******(a)thelounge.net): started proxying to 127.0.0.1:143: user=<********(a)thelounge.net>, method=PLAIN, rip=********, lip=******, TLS, session=<ugAua+i/ewBUcit1>

[Dovecot] index IO patterns
by Cor Bosman 12 May '12

12 May '12

Hey all, we're in the process of checking out alternatives to our index storage. We're currently storing indexes on a NetApp Metrocluster which works fine, but is very expensive. We're planning a few different setups and doing some actual performance tests on them. Does anyone know some of the IO patterns of the indexes? For instance: - mostly random reads or linear reads/writes? - average size of reads and writes? - how many read/writes on average for a specific mailbox size? Anyone do any measurements of this kind? Alternatively, does anyone have any experience with other redundant storage options? Im thinking things like MooseFS, DRBD, etc? regards, Cor

[Dovecot] /var/run/dovecot folder gets deleted on server reboot? ubuntu 10.10
by jacques 11 May '12

11 May '12

Hi After rebooting my server connections to the mail system set up there failed - on closer inspection no dovecot process was running or got started. When running as root /usr/share/sbin/dovecot -c /etc/dovecot/dovecot.conf got error on console /var/run/dovecot/auth-master could not be opened and found no /var/run/dovecot folder!. Is there better script to place in /etc/init.c/ to start dovecot (which will not fail silently?) Any idea what would remove the folder on ubuntu 10.10, running dovecot 2.1.5 and postfix 2.1.7? Any suggestions? Jacques

[Dovecot] Postfix Query
by Tim 10 May '12

10 May '12

Hello, Another question!! Was just trying to sort out mail delivery to subdomains. I set up my system so that I have a mail address of tim(a)subdomain.example.com. I've sorted out Postfix to correctly identify this and pass on to Dovecot for delivery but Dovecot doesn't seem to deliver where I want it to. Ideally I would like to have a structure so that mail is delivered to /var/mail/example.com/subdomain/user My users are stored in MySQL and they are being pulled out correctly, but dovecot is delivering to /var/mail/subdomain.example.com/tim Looking at my logs it seems that the mail location is being picked up not being acted on... May 10 21:51:20 auth(default): Info: master out: USER 1 tim(a)subdomain.example.com maildir=example.com/subdomain/tim uid=mailuser gid=mailgroup quota_rule=*:bytes=2147483647 ...a bit further down... May 10 21:51:20 deliver(tim(a)subdomain.example.com): Info: auth input: maildir=example.com/subdomain/tim ...then further down it seems to change all of a sudden... May 10 21:51:20 deliver(tim(a)subdomain.example.com): Info: maildir: data=/var/mail/subdomain.example.com/tim/Maildir May 10 21:51:20 deliver(tim(a)subdomain.example.com): Info: maildir++: root=/var/mail/subdomain.example.com/tim/Maildir, index=, control=, inbox=/var/mail/subdomain.example.com/tim/Maildir Bit confused! Any help would be appreciated! Cheers, Tim
