Odd email problem

[jason]

This looks like he is using your mail server as an SMTP server in his
Outlook configuration? If so you need to either configure SMTP Auth on
your end, or have him use his local ISP's SMTP. If this is what's
happening and he **needs** your smtp service you have a couple of other
options too. Explore "smtp after pop3", SMTP Auth or if he has a
dedicated IP address, allow his IP alone in your /etc/mail/access. I
have entries like this 

64.222.187.34                   RELAY

Does that answer?
