[SC-Help] looks like a dynamic host, untrusted as relay

[Ron Parker]

Hi.  Recently, all the reports I have submitted have listed my 
mailserver IP as the source of the spam (even though in the message 
header, you can see the actual source IP(s) in the line(s) below the one 
where my host receives the mail).  When I look at the spam processing I 
see a line indicating that my IP "looks like a dynamic host, untrusted 
as relay".  My mailserver is not a dynamic host.  So, the question is:  
What do I do to resolve this issue?  Thanks.
