Re: [Dovecot] How to add the missing maildir folders
by interfaSys sàrl 06 Oct '10

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

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.

[Dovecot] Virtual Folders
by qmail＠top-consulting.net 05 Oct '10

05 Oct '10

I have the following setup: dovecot --version 1.2.10 namespace private { prefix = virtual. separator = . location = virtual:~/Maildir/virtual:INDEX=MEMORY } protocol imap { mail_plugins = quota imap_quota fts fts_solr antispam virtual #pwd ~/Maildir/virtual/all #cat dovecot-virtual * all The problem is that I can't access any of the virtual folders. Logging the IMAP conversation showed me this: 5ptq SELECT "virtual.all" frdv IDLE 5ptq NO Mailbox doesn't exist: all (all)^M + idling^M frdv OK Idle completed.^M What am I doing wrong ?

[Dovecot] question on quota configuration on 2.0.5
by Leonardo Rodrigues 05 Oct '10

05 Oct '10

Hi, On dovecot 1.2 i had the following configuration on my dovecot-sql.conf file: password_query = select endereco as user, password, '/var/spool/mail/%u' as userdb_home, 'maildir:/var/spool/mail/%u' as userdb_mail, 8 as userdb_uid, 12 as userdb_gid, concat('*:storage=', quota) as userdb_quota_rule, 'Trash:storage=100M' as userdb_quota_rule2 from emails where endereco = '%u' and ativa = '1' special attention to 'Trash:storage=100M' as userdb_quota_rule2 after migrating to 2.0.5, i got this warning on the logs: Oct 3 16:06:41 ns2 dovecot: imap(user(a)domain.com), rip=127.0.0.1, lip=127.0.0.1: Warning: quota root User quota rule Trash:storage=100M: obsolete configuration for rule 'storage=100M' should be changed to 'storage=+100M' Oct 3 16:08:09 ns2 dovecot: imap(user(a)domain.com), rip=127.0.0.1, lip=127.0.0.1: Error: quota: Unknown namespace: Trash about changing 100M to +100M, that's OK, no problem .... but even after changing that, i still keep getting the 'unknown namespace' message. question: what's the correct way of doing this configuration on dovecot 2.0 ? The idea of this configuration is to give plus 100M of the user's quota on the Trash folder, thus avoiding problems with out webmail which copies messages to trash before erasing from the actual folder. -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it
