Likely an issue with CLAWS email. If you can arrange a network capture of a non-SSL remote CLAWS connection, try checking whether there's a hidden character (NULL, .etc.) being sent. It's also telling that it works for some accounts, and not for others. Try rebuilding the user's index cache by removing it (save a copy!) and see if that makes it work. If it does, you can send the buggy caches to the developer and see if they can figure it out. Joseph Tam <jtam.home(a)gmail.com>

STAT command failure
by Andrew Charnley 24 Oct '17

24 Oct '17

Hi, Regarding STAT which appears to have an issue with Dovecot:- [23:50:46] POP< +OK Dovecot ready. [23:50:46] POP> USER xxxxx [23:50:46] POP< +OK [23:50:46] POP> PASS ******** [23:50:46] POP< +OK Logged in. [23:50:46] POP> STAT [23:50:46] POP< -ERR Unknown command: I have enabled the logging as previously instructed for pop3 however this is only up to the point of login. After this there is no further information. Login is successful. Other commands are working fine, I can use Evolution which doesn't use STAT and access email fine. The issue only came to light due to an attempt to change to Claws email. Strangely one of my four accounts on the same server does work. There is no difference in the settings and I've tried recreating them on both Claws and the server. The Claws team are 100% sure it's a Dovecot issue. This is the latest version available with Centos 7 so not the most up-to-date but I can't see anything in the logs which would suggest a change for 2.2. Regards, Andrew

master/master replications v. 2.2.32
by Jorge Canto E. 23 Oct '17

23 Oct '17

Hi, in the past I set up a master/master replication through TCP using dovecot 2.2.10 on both servers and everything is running fine, I filter the users to replicate using the iterate_query on file dovecot-sql.con.ext; now I want to set up a new replication between two new servers running dovecot 2.2.32 but the replicator service tries to replicate every user on my database even when the iterate_query is correctly set up and the command "doveadm user '*' " shows only the users I want to replicate, I think I am missing something but I do not know what. Thank you so much for your help. Jorge C.

dovecot, winbind and user folders
by Kristian Rink 23 Oct '17

23 Oct '17

Folks; I'm in the process of migrating an existing IMAP infrastructure to something that should be dovecot based. We live inside a Windows AD 2012 realm and the servers use winbind for user authentication as well as pam configurations to automatically create user home dirs whenever the user logs in first. Can something like this (mailbox is automatically generated whenever user logs in first) be done with dovecot too? Any best practises on how to work in such setups? I want to keep setup effort required for new users as low as possible... ;) Thanks in advance and all the best, Kristian
