Server migration
by Gandalf Corvotempesta 01 Nov '16

01 Nov '16

Hi i have to migrate, online, a dovecot 1.2.15 to a new server. Which is the best way to accomplish this? I have 2 possibility: 1) migrate from the very old server to a newer server with the same dovecot version 2) migrate from the very old server to a new server with the latest dovecot version can i simply use rsync to sync everything and, when the sync is quick, move the mailbox from the old server to the new server? My biggest concern is how to manage the the emails that are coming during the server switch. Let's assume a 50gb maildir , the first sync would require hours to complete (tons of very small files) do i can't shutdown the mailbox. The second sync would require much less time and would also sync the email received during the first sync (but the mailbox is still receiving new emails) now, as third phase, i can move the mailbox to the new server (by changing the postfix configuration) so that all new emails are received on the new server and then start the last rsync (by removing the --delete flag or any new emails would be deleted as not existsnt on the older server) Any better solution?

Released Pigeonhole v0.4.16 for Dovecot v2.2.26.0.
by Stephan Bosch 01 Nov '16

01 Nov '16

Hello Dovecot users, Here's the definitive 0.4.16 release. There were no changes since the release candidate. The reported replication issues are still open, since we haven't been able to reproduce them so far. Changelog v0.4.16: * Part of the Sieve extprograms implementation was moved to Dovecot, which means that this release depends on Dovecot v2.2.26+. * ManageSieve: The PUTSCRIPT command now allows uploading empty Sieve scripts. There was really no good reason to disallow doing that. + Sieve vnd.dovecot.report extension: + Added a Dovecot-Reporting-User field to the report body, which contains the e-mail address of the user sending the report. + Added support for configuring the "From:" address used in the report. + LDA sieve plugin: Implemented support for a "discard script" that is run when the message is going to be discarded. This allows doing something other than throwing the message away for good. + Sieve vnd.dovecot.environment extension: Added vnd.dovecot.config.* environment items. These environment items map to sieve_env_* settings from the plugin {} section in the configuration. Such values can of course also be returned from userdb. + Sieve vacation extension: Use the Microsoft X-Auto-Response-Suppress header to prevent unwanted responses from and to (older) Microsoft products. + ManageSieve: Added rawlog_dir setting to store ManageSieve traffic logs. This replaces at least partially the rawlog plugin (mimics similar IMAP/POP3 change). - doveadm sieve plugin: synchronization: Prevent setting file timestamps to unix epoch time. This occurred when Dovecot passed the timestamp as 'unknown' during synchronization. - Sieve exprograms plugin: Fixed spurious '+' sometimes returned at the end of socket-based program output. - imapsieve plugin: Fixed crash occurring in specific situations. - Performed various fixes based on static analysis and Clang warnings. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.16.ta… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.16.ta… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

2.2.26.0: Error: redis: Unexpected input (state=0): -ERR max number of clients reached
by Tom Sommer 01 Nov '16

01 Nov '16

I use redis as quota backend (currently). After upgrading to 2.2.26.0 I see a ton of "Error: redis: Unexpected input (state=0): -ERR max number of clients reached" errors. It looks like either more Redis connections are being made, or Redis connections don't time out/are reused correctly anymore. No such errors were seen in 2.2.24. -- Tom

by jean francois pion 01 Nov '16

01 Nov '16

hello, i'm quite a newbie to the mail server instalation and admin (you must start one day !) i would like to use a rapberry pi to build a system to get the mails from different mail accounts via pop, to store them in the raspberry memory an be able to get them with my thunderbird client on the different computers on my local network. no need to accesse them via internet it is for local use only. the puropose is to avoid gettin my fai mail box full and loosing mails (quite a big mail traffic ) no need for spamkiller i've got what i want already on the computer no need for an smtp relay the computer can acces the fai smtp, is dovecot able to do that ? thank you sorry for the bad english -- -- JF Pion *Quand je suis allé à l'école, ils m'ont demandé ce que je voulais être quand je serai grand.

IP Addresses
by Stephen Hanselman 01 Nov '16

01 Nov '16

Good Morning, Can someone point me to the area in Dovecot that deals with incoming IP addresses. Specifically I want to determine if it is possible to "spoof" the address or is the address I look at in the headers the actual address that made the connection request (hopefully it is). Thank you Steve Hanselman

Safe to run migration on live/production server?
by mrobti＠insiberia.net 31 Oct '16

31 Oct '16

I have an old mbox formatted INBOX and folders that need to be converted to a Maildir. Can I run the dsync command when the server is live and Dovecot LMTP is delivering new mails to the same user? Will it be able to preserve UIDs and not confuse any indexes? I started the job with deliveries disabled so the conversion could complete, but it's taking too long. I want to know if I can re-enable mail deliveries and not cause problems. I see it building a massive number of files in the user's Maildir/tmp folder, which I presume is normal. By the way, what's the size multiplier for mbox to maildir for many small emails only a couple K each? I'm finding it's a lot more disk space for maildir in this case.
