Program received signal SIGTTOU, Stopped (tty output). But I found out that it
happens only when I run it from mc shell, it works when I run it from pure bash.

No, even after ulimit -c unlimited it didn't produce core file. But as now
I was able to run milter-greylist under gdb:

Anything else I should check? I didn't exit from gdb yet.
