Maybe smtp is working through inetd and so it could be filtered via tcp
wrappers as well. I'd recommend that you take a look at hosts.allow and
hosts.deny (in /etc).

Also, your "cant connect to smtp service" message is not very helpful. I
think it could be better that you do telnet smtp_host 25 and post the
output, sure it will help more :-)
