Replication - hostname issue
by Petter Gunnerud 05 Jan '16

05 Jan '16

I have postfix/dovecot setup on a virtual gentoo server. It's been in service for almost two years without any issues. Now I want to set up a spare server to replicate mails from the one running. I copied the vm files to the second host server, changed the ip, hostname and hosts file for the copy and followed the dovecot replication doc. The last point in the doc tells to rundovecot --hostdomainto make sure the hostnames differ... To my surprise the command returned "localhost" on both servers. How do I set the hostname for dovecot service?(The hostname command returns the servers hostnames.)Will a change in dovecot hostname make all clients redownload all their mail? A second question. When configuring dovecot replication. Should the settings be done on the master server or the stand by server, or both? (Doc doesn't say anything regarding this) PG

postmaster domain
by Timothy Murphy 04 Jan '16

04 Jan '16

I recently upgraded a remote server to CentOS-7.2, after which email stopped coming through. I suspect that this was probably due to the fact that I had started a version of dovecot installed some time ago. I found messages in /var/log/maillog like Jan 4 12:56:56 alfred postfix/lmtp[7612]: 20A662202B4: to=<root(a)gayleard.eu>, relay=alfred.gayleard.eu[private/dovecot-lmtp], delay=34272, delays=34272/0.16/0.01/0.05, dsn=4.3.0, status=deferred (host alfred.gayleard.eu[private/dovecot-lmtp] said: 451 4.3.0 <root(a)gayleard.eu> Invalid user settings. Refer to server log for more information. (in reply to RCPT TO command)) Googling for this, I found the suggestion that one should insert the following postmaster_address line in /etc/dovecot/conf.d/20-lmtp protocol lmtp { postmaster_address = postmaster(a)alfred.eu # Space separated list of plugins to load (default is global ail_plugins). mail_plugins = $mail_plugins sieve } (alfred.eu being the server's domain). This seems to have solved the problem, after re-starting dovecot. I'm wondering if this was an issue that arose some time ago, and if so whether my solution was the recommended one? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

Released Pigeonhole v0.4.11.rc1 for Dovecot v2.2.21
by Stephan Bosch 04 Jan '16

04 Jan '16

Hello Dovecot users, First, a happy new year to you all! :) In the last few weeks I got quite a few bug reports. I also found a few things myself. Some of the bugs are quite annoying, so a new release is necessary. First, I release RC1. If all is well, I'll release the definitive Pigeonhole v0.4.11 within the next few days. Changelog v0.4.11: - Sieve mime extension: Fixed the header :mime :anychild test to work properly outside a foreverypart loop. - Several fixes in message body part handling: - Fixed assert failure occurring when text extraction is attempted on an empty or broken text part. - Fixed assert failure in handling of body parts that are converted to text. - Fixed header unfolding for (mime) headers parsed from any mime part. - Fixed trimming for (mime) headers parsed from any mime part. - Fixed erroneous changes to the message part tree structure performed when re-parsing the message. - LDA Sieve plugin: Fixed logging of actions; sometimes the configured log format was not followed. - LDA Sieve plugin: Fixed bug in error handling of script storage initialization. - Sieve Extprograms plugin: Ignored ENOTCONN error in shutdown(fd, SHUT_WR) call. - Fixed duplication of discard actions in the script result. Each discard was counted as a separate action, which means that action limit would be crossed too early. - Made sure that quota errors never get logged as errors in syslog. - Fixed handling of implicit keep for a partially executed transaction that yielded a temporary failure. - Fixed handling of global errors. If master and user error handler were identical, in some cases the log message could be lost. - Fixed AIX compile issue in message body parser. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.11… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.11… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

I can do this with IMAP client like Thunderbird, but how I can do it on server? doveconf -n | grep quota mail_plugins = quota, antispam quota = maildir:User quota_exceeded_message = Message quota_rule = *:storage=100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u quota_warning3 = -storage=100%% quota-warning below %u service quota-warning { executable = /usr/local/bin/quota-warning.sh mail_plugins = quota imap_quota mail_plugins = quota sieve For each mailboxes I use quota limits from MySQL. -- С уважением, *Макаров Денис* *почта*: makarovdenis11(a)gmail.com <mailto:makarovdenis11@gmail.com> Best regards, *Makarov Denis* *email*: makarovdenis11(a)gmail.com <mailto:makarovdenis11@gmail.com>
