[SunHELP] How to check sendmail ?

[Marek Grinberg]

Hello again,

/var/log/syslog revealed that /etc/hosts was incomplete, so I changed it 
to contain:
a.b.c.d  neat-test       loghost mailhost        neat-test.x.com

# mailq -v
Mail queue is empty

Mail to root works OK now, but when I send to an external user it fails:
# mail -t marek.grinberg at tele2.se
aaa
.
# mail

?

Apparently the sendmail configuration file does not include a SMTP 
entry. How do I set it up ?
