[Dovecot] Postfix: Command died with status 89: "/usr/lib/dovecot/deliver"
by Jacob Elder 01 Mar '06

01 Mar '06

One of our servers running Dovecot 1.0.beta3 and dovecot-lda has failed to deliver a few messages and I can't figure out why. Very few messages bounce and I don't see any common thread between them other than time. The 15:19:11 message was a company wide announcement and the other 4 servers (identical configuration) were able to deliver it.

[Dovecot] Maildir Quotas
by wink＠gettcomm.com 28 Feb '06

28 Feb '06

Hey guys, Does anyone have any ideas as to when this may be implemented? I'd love to be able to use dovecot, but without quota support, it just won't fit the bill. Is there any developer documentation as to what would be required to fully support maildir quotas as I'd be willing to help implement it assuming it's not going to take me weeks to become familiar enough with the codebase. Thanks

[Dovecot] using dovecot for postfix sasl
by h＠hpjt.net 28 Feb '06

28 Feb '06

I have followed the Dovecot/Postfix/SASL howto, and modified the main.cf and dovecot.conf files, yet when trying to authenticate during a postfix SMTP session the log reports: "postfix/smtpd....warning: SASL authentication failure: Could not open db" Dovecot itself is authenticating IMAP logins correctly, and it is creating the auth file in the location specified under /var/spool/postfix/private. Why is postfix not able to get to the Dovecot auth mechanism? Thanks. Hugh

[Dovecot] Error "make install" of dovecot 1.0b3

28 Feb '06

I just downloaded dovecot 1.0b3 and running "make install" gives me an error This seems like a fairly simple bug in the Makefile ... but I'm not sure if maybe its a symptom of something more complex. I've tried "make uninstall" , "make install" and removing the entire /usr/local/lib/dovecot tree and same thing. dovecot does run ... but for other reasons I'm having problems getting it to work so thinking maybe this error could explain things System: Linux [root@lee dovecot-1.0.beta3]# uname -a Linux lee.calldei.com 2.6.11-1.27_FC3 #1 Tue May 17 20:27:37 EDT 2005 i686 athlon i386 GNU/Linux CPU: x86 Filesystem: standard linux fs.

[Dovecot] Sorting order after mail move
by Václav Haisman 28 Feb '06

28 Feb '06

Hi, when I move some recent mail from some mbox folder into Maildir folder the moved email sorts as the first (on top) in the folder while it should be on the bottom with the rest of the recent emails in the folder. This happens only when moving from mbox folder to Maildir folder. I am not sure if it is really Dovecot bug or not but I suspect it could be so because it only happens in this one specific scenario.

[Dovecot] two possible inboxes, possible to check both?
by adcx＠server101.com 28 Feb '06

28 Feb '06

We're currently in the process of organising a migration from mbox to maildir mail storage on our server, and are hoping to phase this in gradually using dovecot's capabilities. Procmail has already been configured to deliver mail to either the existing mbox or to a new maildir for the user based on the (non)existence of a .converted file in their home directory. Where we are having problems is the pop3 retrieval side of things. Basically, we're chasing a setup where dovecot will first check to see if /mail/<first letter of username>/username exists (indicating that the account has had the .converted file created and new mail has since been delivered to that user in the new maildir format). If this directory does not exist, it should fallback to retrieving mail from the as-yet unconverted mbox, /var/mail/username. We've tried different combinations of namespaces and default_mail_env values to achieve this without success. One attempt which has come particularly close was: 1. Leaving /etc/dovecot.conf almost entirely default. The auto-detection ability of dovecot performs the following (output to /var/log/maillog): Feb 28 14:57:45 mouse dovecot: pop3(joe): maildir: access(/home/joe/Maildir, rwx): failed: No such file or directory Feb 28 14:57:45 mouse dovecot: pop3(joe): maildir: couldn't find root dir Feb 28 14:57:45 mouse dovecot: pop3(joe): mbox: root exists (/home/joe/mail) Feb 28 14:57:45 mouse dovecot: pop3(joe): mbox: INBOX exists (/var/mail/joe) Feb 28 14:57:45 mouse dovecot: pop3(joe): mbox: root=/home/joe/mail, index=/home/joe/mail, inbox=/var/mail/joe Feb 28 14:57:45 mouse dovecot: pop3-login: Login: user=<joe>, method=PLAIN, rip=192.168.6.20, lip=192.168.6.2 Feb 28 14:57:45 mouse dovecot: pop3(joe): Logout. top=0/0, retr=0/ del=0/0, size=0 This is almost exactly what we're chasing, except the new Maildir is not going to be created in the user's home dir, it will be in /mail/<first letter of username>/username. All attempts to make this last adjustment have ultimately modified the behaviour of dovecot so that it only checks the one source explicity given, and then simply fails if it does not exist, unlike the unconfigured behaviour illustrated above where it is able to fallback to a secondary source. A '2nd_default_mail_env' is the type of variable I'm looking to define, if that makes it any clearer. Any advice much appreciated, I've already searched most of the archives for this list without finding anything similar.

[Dovecot] Impact of log files on performance
by vmstech 27 Feb '06

27 Feb '06

Hi - im trawling through my config trying to reduce chances of timeouts etc - I use postgres for all the dovecot and exim4 authentication and location of mail directories etc - and found that by eliminating logging (or reducing to almost none) the queries invovled have gone from >500ms to <3ms - Just wondering if I'll get similar performance gains with dovecot (which is set to be verbose as I could) - esp during connection thx Glenn
