usernames with/without domain - my solution
My existing pop3/imap environment is courier imap + vpopmail + qmail with MySQL backend. I'm looking at migrating this to Dovecot. Currently I have multiple instances of Courier bound to different loopback IPs (the IPs correspond with the virtual IPs on a server load balancer). When a user authenticates they don't have to specify a domain - if they don't, Courier will use a

Poor pop3 over nfs performance
Hi, About a week ago I upgraded our reasonably heavily loaded mail servers from a pretty recent courier version to dovecot-1.1rc10. IMAP performance on dovecot is amazing, however POP3 performance is worse than courier :-( I have uploaded some munin graphs taken today to http://linweb.atlas.pipex.net/dovecot/; the dovecot server is handling about 2000 pop logins/sec and 300 imap sessions (but

Unbreakable NFS locking issues...
Hello All, We are struggling to find a solution to a problem we are encountering with a load-balanced email setup. Currently, we have a Coyote loadbalancer, and 3 Postfix/Dovecot nodes that then get their information from a mysql database. The problem is that after a couple weeks, we start seeing NFS locking issues occur, which then takes email completely down, requiring a site visit to

Maildir size report for imap?

Dovecot deliver uidlist issues

Effects of going read-only on dovecot & pop/imap clients

RFC: Storing indexes in a (remote) database to increase dovecot scalability
...a filesystem is easy so I'm not suggesting that we abandon this route, but for truly large infrastructures I think being able to use a database system would have significant advantages in each of these four areas.

Post-login scripting with mail_drop_priv_before_exec in dovecot2
Hi, I'm in the process of upgrading from dovecot v1.1 to dovecot 2. We fetch uid/gid user information from a database and also use post-login scripting with mail_drop_priv_before_exec = yes which means the postlogin script is executed with the permissions of the user we have found in the database. According to the dovecot2 wiki page, to get this behaviour in version 2 we have to set the

Port variable in LMTP userdb lookups?
Hi all, I'm currently changing some systems to use the redirector service, which means that to get local deliveries going I need to get lmtp set up so it can be redirected as well. This is working fine, however we have a number of different ports running on our servers depending on which brand a customer is using. When the time comes to do the user look up, we use (port, user, domain) to

Director to keep redirecting users to the same server even after all sessions closed?
Hi there, Just wondering how easy it would be to make the director continue to send a user to the same server (assuming it's still in the pool) for say 90 seconds after they have last been active (ie lmtp or pop/imap)? Basically we are working in quite a heavily cached environment so it takes perhaps 60-90 seconds for our imap servers to properly flush to our network storage meaning if

Passdb disconnected unexpectedly when trying to do Director with LMTP
Hi there, I'm running Dovecot 2.0.16 just set up the director with cut&paste from the wiki. It's working & running fine for pop/imap connections (as verified by doveadm director status user), however when I specify 'RCPT TO' for a (tcp) lmtp connection straight away I get: 451 4.3.0 <xxx at yyy.com> Temporary user lookup failure and in the logs:

[PATCH proposal] make dsync preserve pop3_uidl_format
Hi there, I ran into an issue yesterday (dovecot 2.0) whereby when we dsync messages from a local machine (sdbox) to a remote (Maildir) which have different pop3_uidl_formats configured, the uidl format is not preserved. There doesn't seem to be any way to force this in the code, although I suspect that Maildir sources with saved pop3 uidls would pass them correctly. Attached is a rough patch

penalty configuration and proxy servers
Hi there, I've had a look through the wiki and a quick look through the source for penalty configurations (dovecot 2.0.9) but I've not found anything to do with configuration options for this functionality. I'm basically wanting to disable a particular host/subnet from the penalty setup. In our case we have some webmail servers that do get attacked however most of the traffic is
