[buug] Sendmail/SMTP problem on FreeBSD

[D. L]

Here are the answers to your questions:

1.  Sendmail
2.  I have not checked the logs yet.  (You will have to understand, I 
am very new to both FreeBSD and Sendmail.)
3.  The problem is with any e-mail address.
4.  I ran a Reverse DNS lookup and the IP address matches the name 
for the mail server.

Thanks,
