Hello, I have a new director ring I am setting up on centos 7 with dovecot 2.3.1. I haven't been able to replecate this in testing, but as soon as I start pushing production traffic to the new ring I see dozens of these in the logs: Apr 18 00:34:00 d.director.imapd.sonic.net kernel: imap-login[163107]: segfault at 10 ip 00007ff625698dd5sp 00007ffe4b77bb28 error 4 in

When in the process of testing out the 2.3.0 version of Dovecot, we noticed that on a busy server, imap-login can sometimes take 100% CPU and remain there indefinitely. We grabbed a gdb trace while it was happening: dovenull 36053 31.2 0.0 60460 17316 ? R 04:38 11:55 dovecot/imap-login root at server [~]# strace -p 36053 Process 36053 attached ^CProcess 36053 detached root at server

Hello: I've been looking forward to getting my mail server up to Dovecot 2.2+ to be able to use the sync mechanism. I run my own mail server just for myself, with a few different accounts, and want to keep a master and backup server in sync. I'm running the Ubuntu server 14.04.1 mail stack which features Dovecot 2.2.9 (and Postfix). My setup is to use system users (userdb passwd /

Hello, I'm trying to set up the submission proxy, but if I set submission_relay_ssl = starttls, it crashes. Without it, it works. Please find the details below.

Where would I find the core file? I'm not finding anything obvious.

Hi Aki, first thanks for the quick fix. Unfortunately, it only resolves the issue partially. For the ?To: undisclosed-recipients:;?, it works now. For ?To: ? it still crashes (i. e. what I did with my manual lmtp dialog). Michael > On 13.
