[Dovecot] copy and empty userA folder1, append to /var/mail/userB
by mathog 08 Sep '11

08 Sep '11

Dovecot 2.0.13 on a 64 bit linux. We have an archiver account on one machine. Most mailing lists that handles go directly to it and everything is fine. However, there is one campus list that will only send to real people. So for that one I subscribed. When one of these messages comes in, which is 1-2x per week, I copy it to an export folder and then manually run a script which does: cat ~me/mail/export >>/var/mail/archiver echo "" > ~me/mail/export That worked fine on our last system, but dovecot doesn't like it. It leaves the imap indices for the export mailbox in an inconsistent state, so that roundcube (through dovecot) refuses to drop messages into it. The error message roundcube emits is: ServerError: Mailbox isn't a valid mbox file. Presumably the second half is from dovecot. I need a supported way to go about this, so that the next time one comes in I can copy to that folder again. The export mailbox is always completely emptied. It would suffice if there was some way to force dovecot to create "empty"" .imap/export: dovecot.index.cache dovecot.index.log files. Note this isn't a problem for the archiver itself, since it doesn't have any imap indexed files. Suggestions? Thank you, David Mathog mathog(a)caltech.edu Manager, Sequence Analysis Facility, Biology Division, Caltech

[Dovecot] limit number of simultaneous lmtp deliveries ?
by Jan-Frode Myklebust 08 Sep '11

08 Sep '11

We have quite a few frontend mail gateways that deliver incoming email trough our dovecot director (lmtp proxy) to the backend lmtp servers, and are seeing this logged on the frontend mail gateways: Sep 5 10:51:56 mailgw1 postfix/lmtp[23443]: 0E2F41C01A: to=<me(a)example.com>, relay=loadbalancers.example.com[192.168.42.15]:24, delay=61, delays=0.02/0.3/31/30, dsn=4.4.0, status=deferred (host loadbalancers.example.com[192.168.42.15] said: 451 4.4.0 Remote server not answering (DATA output timeout) (in reply to end of DATA command)) It's a bit unclear to me if this leads to duplicate deliveries, or just delayed deliveries, but -- is there any way to limit the number of simultanous deliveries on either the dovecot director or the backend lmtp-servers ? Will "process_limit=10" work for "service lmtp"? -jf

[Dovecot] ManageSieve with SSL/TLS only
by Karol Babioch 08 Sep '11

08 Sep '11

Hi, I'm quite new to Dovecot and ManageSieve, so probably I've missed something, although I couldn't find any hints in the wiki. I'm interested in running ManageSieve with SSL/TLS only. So is there any way to reject any non encrypted connections? I couldn't find any parameter for this purpose. I'm currently using dovecot 1.2.15 provided with Debian Squeeze, but I couldn't find any parameter in the 2.0 branch neither. Best regards, Karol Babioch

[Dovecot] Shared Mailboxes with VirtualUsers and mail_location retrieved from ldap

Hello, I spend a couple of days configurating a new installation of dovecot 2.0.14 with virtual accounts and NFS storage for maildir home/mail directories. At this point I need shared mailboxes but since user mail/home locations are ldap attributes, how is it supposed I must configure this for shared mailboxes? for the users' mail/home directories I set this line: user_attrs = mailbox=mail=maildir:/var/maildir/%$,homeFilter=home creating a namespace like the below one for shared mbx throw a lot of errors: namespace { type = shared separator = / prefix = shared/%%u/ subscriptions = no list = children #location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u location = mailbox=mail=maildir:/var/maildir/%$ } I would like to hear if anyone has this configuration running.
