[SLUG] postfix and other connections

[kevin@xxxxxxxxxxxxxxx]

First of all I would like to thank those who helped me with my samba issue I 
will get back to it shortly.

I have another issue, and it is disturbing me lately.
I have been getting emails from other sites but saying they are from my domain.
Here is a copy of the header from one of the emails. Also Spamassassin is 
saying this email is ok as it has a -ive interger.
