hi, I've just upgraded our dovecot installation to the most recent debian package (0.99.20050712) and now I'm running into some weird problems.

[Dovecot] postfix+dovecot+sieve?

Quick newbie question... is anybody using postfix+dovecot+sieve? Postfix doesn't natively support Sieve, and neither does Dovecot, so I'm not quite sure how to simply add Sieve to my configuration. Thanks in advance... - Jon

This is Debian testing, 512 MB RAM, about 20 users per server. We use libnss-ldap and libpam-ldap for all users other than root. Samba, SSH, saslauthd (for Postfix), login, etc all work as expected. There is a 5th server that is identical to the other 4 except is NOT using libpam-ldap, and dovecot does not hang on this machine. Any ideas? -- Jacob Elder [View Less]

At the time of writing I had a particular advantage: I did not know, or had mostly forgotten, the peculiarities of the imap protocol.

[Dovecot] Binc IMAP "IMAPdir" style layout

Hi, I'm in the process of migrating several years worth of mail to be accessible via an IMAP server. Some time ago, I evaluated both Binc IMAP and Dovecot and found Dovecot to be much faster on large folders, which is quite important to me. One thing I did not however manage to determine from the documentation on namespaces is whether or not it is possible to implement what Binc IMAP calls an "IMAPdir" style layout. IMAPdir lets me layout mailboxes in the filesystem like so: $HOME/ … [View More]

It was only once I realised that when I copied and renamed my .subscription file to subscription, did it all work. Obviously the mistake was on myside but telling debconf to over write the conf file, but I find it a bit weid that when on killing dovecot and then restarting the with the old conf file, it still did not work. To be honest, im a bit lost as to how im going to rectify this, but I know that I want to upgrade my packages. If you can help in anyway, it would be most appreciated.

[Dovecot] Problem with dovecot and system crashing
by Colin Kingsbury 14 Aug '05

14 Aug '05

Hi all, I am running dovecot on a linux server (FC3) in conjunction with Sendmail. My configuration is quite vanilla and I am having the following problem: occasionally (once every 3-10 days) the dovecot server will become unresponsive and attempting to access mail via pop3 will produce an error message on the client side. As best as I can tell, the dovecot process dies because if I restart it with /sbin/service dovecot restart I get [failed] on the stop and [ok] on the start. Now, here's … [View More]
