Hi Timo et all.
At last I found with unix socket wouldn't connect and it works now.
However after auth, imap crashes with signal 6.
This happens on 1 machine, the other (unixware too) work fine.
The stack trace doesn't make much sense
here it is anway...

Core image of imap (process p1) created
CORE FILE [makedev in cmd-status.c@sys/mkdev.h]
SIGNALED 8 (fpe code[FPE_INTDIV] address[0x804e38b]) in p1

The log says Trying to allocate 0 bytes
and imap gets killed.

Does it ring any bells?

So the earlier problems are gone? How did you get it fixed?

Well, that really doesn't make any sense. It just can't happen, so those
function names were looked up wrong.

Hmm. There are quite a many ways for the code to get here. I tried
looking if I could find some way to cause this myself, but didn't
succeed. So pretty difficult to get fixed without a correct backtrace..
