Summary: IMAPd segfaults using CONDSTORE
Description:
After upgrading to dbmail 3.2.0 the IMAPd tends to crash often. Sometimes
within a few seconds after restart (depending on how many users are
accessing the server).
Debugging the core dumps shows that
in _ic_status_enter at imapcommands.c:1520
the following line segfaults
self->mailbox->condstore = true;
gdb shows that self->mailbox is NULL.
Maybe a simple check against NULL before accessing the variable could fix
it. On ther other hand I do not know whether it should be possible for
mailbox to be NULL in such a situation.
I worked around this issue by remove CONDSTORE from the capability list
announced by the server to the client. Now I do not notice any crashes
since the clients do not use CONDSTORE anymore.

18:08:35 GMT) which is included in dbmail 3.2.3 addressed this issue.
So far I haven't noticed any more segfaults.
Thanks a lot!
