by Henrique Fernandes 06 Oct '10

06 Oct '10

Hey, i am gonna migrate 240 GB of emails. To a new server with dovecot 2.0.4 and i am gonna also change the format from mbox to maildir. Everything is pretty ready. But i now need two things. First is, is there any command to rebuild index files in dovecot ? And i need to force a initial squat build, need comand for it also. It is about 5 thousands accounts. Its prefere have this built in dovecot than run a script that log in every sing account to make dovecot index the files, and after it make a small search to make initial squat also. Any one can help ? []'sf.rique

Looks like it's also possible to use doveadm http://wiki2.dovecot.org/Tools/Doveadm/Mailbox

Re: [Dovecot] How to add the missing maildir folders

Hello, There is the autocreate plugin[1], but the problem is that a user cannot delete those mailboxes. It can be a problem for people using clients in different languages and that want mailboxes in these languages. I would be great if Dovecot could make some of these automatic mailboxes optional.

[Dovecot] release plan for dovecot antispam plugin?
by Tom Hendrikx 06 Oct '10

06 Oct '10

Hi, I noticed that someone took over the development of the dovecot antispam plugin, and the is currently hosted at dovecots hg repo. Great to see that the plugin is not dead! ;) I created a gentoo ebuild that builds the plugin from the repo, and the plugin seems to work nice with dspam (using mailtrain backend). I'm running a checkout from Tue Sep 21 16:14:48 2010. However, it is lacking a release so distributions can also easily update the plugin. Is there any news on this? Regards, Tom

[Dovecot] LMTP proxy too many DATA output timeout (perhaps)
by Luca Palazzo 05 Oct '10

05 Oct '10

Hi All, we are getting a lot of this message from dovecot director. They seem to be too many. Backend servers do not log anything and postfix logs a lot of these errors. It seems that dovecot strategy handgling data output timeout when proxying LMTP is or too aggressive or may have some other problem. This error generate sometime a lot of dupicate deliveries, probably because meanwhile real server has finished delivering the mail, proxy drops the connection. Another symptom, maybe related to duplicate uid patch, is that we are receiving blank email. What may I look further? Regards Luca

[Dovecot] Proxying LMTP - Auth PASS lookup failed
by Edward Carraro 05 Oct '10

05 Oct '10

I'm trying to configure my proxy/director server, which proxies imap/pop/managesieve correctly already, to proxy LMTP to my backend message store server (dovecot+postfix already configured there) This is what I have so far: 10-auth.conf using auth-static.conf.ext instead of auth-ldap.conf.ext (switching to this made proxying imap/pop/managesieve work) 10-director.conf protocol lmtp { auth_socket_path = /usr/local/var/run/dovecot/director-userdb } 10-master.conf (changed user from vmail to dovecot as it was giving permission denied error before -- on the backend dovecot server this is still 'vmail') unix_listener auth-userdb { mode = 0600 user = dovecot } 20-lmtp.conf lmtp_proxy = yes auth-static.conf.ext passdb { driver = static args = proxy=y nopassword=y } my dovecot logs show: auth: Debug: password(user(a)dev.domain.com): passdb doesn't support credential lookups lmtp(1261): Error: user user(a)dev.domain.com: Auth PASS lookup failed postfix show: [private/dovecot-lmtp] said: 451 4.3.0 <user(a)dev.domain.com> Temporary user lookup failure (in reply to RCPT TO command) Any ideas? Something missing/incorrect? Thanks!

[Dovecot] Can't receive emails
by Chris 05 Oct '10

Hello everyone, I installed postfix and dovecot (imap + pop) on a debian server. I can send emails via postfix and I could receive emails via dovecot before. Yesterday my server got shutdown and restarted and since then, I somehow have some problems. If I send some emails, I don't receive them in /var/vmail/%d/%n/Maildir But the login works fine (pop and imap). How can I figure out, why there are no mails comming?

[Dovecot] Another dovecot-lda / deliver Segfault
by Michael P 05 Oct '10

05 Oct '10

I just upgraded from 1.2.11 to 2.0.5. When I send mail from a virtual local user, to another virtual local user, the email sends fine (passing though postfix, then amavisd, then to dovecot deliver) and the recipient receives it, but during this deliver segfaults (pointing to libdovecot.storage.0.0.0) and sends an undeliverable message back to the original sender. This does not happen if someone outside the localdomain sends mail, and does not happen sending from local to a remote address, just purely from virtal to virtual locally.
