[buug] Sendmail/SMTP problem on FreeBSD

[Jon McClintock]

Don,

It would be helpful if you provided some more information about your setup:

- Which MTA are you running? Sendmail? Exim? Postfix? Qmail (shudder)?
- Have you checked your logs for any informative error messages?
- Is it a specific email address your user is having troubles sending mail
  to?
- Does the reverse DNS lookup for your severs IP address match what the 
  mail server says it is called?

It could be that the host they are trying to send mail to is doing a reverse
lookup, finding something different, and rejecting it.
