Sieve: adding Date: header when missing
by Daniele Nicolodi 17 Jul '14

17 Jul '14

Hello, there is a way with a sieve rule to add a Date: header when it is missing? Adding one with the time of reception of the message or using the date from the the first Received: header would be good options. Unfortunately I'm receiving some useful automated messages that lack a Date header and this screws up the sorting in my imap clients. I have a script to fix those acting on the Maildir storage, but I would prefer to have the thing solved more radically. Thanks. Cheers, Daniele

Hello list, Is there a way to call a spam filter in dovecot-lda like maildrop uses the xfilter command within the .mailfilter file to do the same? Eric

Hello I want to set readonly over IMAP for users mailboxes at Archive namespace, (and have single user who can move mails there on automated way) This don't work but found that if I add file to /srv/mail.archives/<user>/dovecot-acl containing only owner lr then login to imap (with telnet) and do 1 GETACL Archive I get following result from gdb attached to worker process serving particular connection. Program received signal SIGSEGV, Segmentation fault. acl_mailbox_right_lookup (box=0x7fd75e4e1dc0, right_idx=right_idx@entry=10) at acl-mailbox.c:40 40 if (abox->skip_acl_checks) (gdb) p abox $1 = (struct acl_mailbox *) 0x0 (gdb) # uname -a Linux omelette 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3 x86_64 GNU/Linux ii dovecot-core 1:2.2.13-2 amd64 local build from sources in testing just disabled lucene ps.

If local Dovecot stops working, check lo
by Steve Litt 17 Jul '14

17 Jul '14

Hi all, You probably know this already, but just in case... Let's say you have your email client getting mail from a Dovecot server on the same computer (which is a really good way of doing things, by the way). Then one day your email client starts saying "connection refused" after a suitably long timeout. So then, to find out where things are getting stuck, you do the following command: openssl s_client -connect 127.0.0.1:993 -quiet And you don't even get an OK back. This means it's not your username or password, because you never even got that far. Before spending a lot of time doing diagnostic tests and narrowing it to the root cause, try this as root: ifdown lo ifup lo A malfunctioning lo will cause Dovecot not to connect to clients. My experience with Debian Wheezy is that lo "goes down" a lot, so this is one of the first things I do when odd stuff happens.

Resource Temporarily Unavailable on replicator-doveadm
by Cassidy Larson 16 Jul '14

16 Jul '14

We're running 2.2.13 on two servers with replication. Still trying to get my replication tweaked correctly and I’m noticing a bunch of these errors for the same users over and over again: dsync-server(user(a)host.com): Error: write(/var/run/dovecot/replicator-doveadm) failed: Resource temporarily unavailable The 5-7 that I see all have quite a number of individual mailboxes (20+), I’m wondering if that has something to do with it? Also, my replicator status for full resync requests has been hovering around 2300-2400 the last few days: # doveadm replicator status Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 2410 Waiting 'failed' requests 1 Total number of known users 9836 In checking the replication status for some of the “Resource temporarily unavailable” list from above, if I run it multiple times it outputs different results for the fast and full sync time: # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:20:21 49:43:34 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:10:55 00:10:55 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:10:56 00:10:56 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:10:57 00:10:57 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:20:24 49:43:37 - doveconf output for the replicator service is: service replicator { process_limit = 10 process_min_avail = 2 unix_listener replicator-doveadm { group = mailsys mode = 0666 user = mailsys } unix_listener replicator { group = mailsys mode = 0666 user = mailsys } } Anybody have any clues or suggestions? I’d be much appreciative. Thanks, Cassidy

Sending emails using dovecot auth

Hi All, I have noticed that dovecot / exim on Cpanels appear to support sending emails via exim after authenticating to Dovecot - see message below 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message We are migrating users mail off cpanels into split mta and dovecot servers and are having problems with some users being abble to send emails afterwards. Does anyone understand how the CPanel config works? Thanks Murray
