Thank you, guys! I understand now where's the problem. I tried the
following changes in /etc/mail/sendmail.mc:
DAEMON_OPTIONS(`Port=smtp,Addr=192.168.3.30, Name=MTA')dnl
and
DAEMON_OPTIONS(`Port=smtp,Name=MTA')dnl
And restarted sendmail after that. Neither of it seems to be working.
Now there's no Addr in sendmail.mc and I've got from netstat command:
tcp        0      0 127.0.0.1:25                0.0.0.0:*
LISTEN      7151/sendmail: acce
So, how can I force it to listen to something like 192.168.3.30:25?
By the way, as this machine is sitting behind the router is it possible
at all to access it by e-mail from the outside world?
