Hello,
I've been trying to get managesieve to work for our LAN, but when I try to login from a remote host i always get the following line in the log file: dovecot: child 26014 (login) killed with signal 11
When i enable debuging, it just gives me that line, nothing more. I can only login from the localhost through telnet but not from a remote host. This is a segmentation fault (crash) and therefore definitely a bug in
Brainkiller schreef: the ManageSieve service. But without more information I cannot fix find and fix this bug. You should try to obtain a core dump or a gdb trace as explained at http://dovecot.org/bugreport.html . Debugging the login daemons can be a little more tricky. I usually attach gdb to the managesieve-login process that is handling my connection (using the gdb attach command). Be sure to compile dovecot with debugging symbols enabled (default Debian packages are stripped).
It is also interesting to know when exactly during the login process it crashes. If you login manually from a remote host (as explained in section 6 of http://wiki.dovecot.org/ManageSieve) you will be able to check where it crashes. If you do not use TLS, you can also sniff the traffic between client and server using ngrep to see where the login process dies.
