I think if you followed the chain, Dan and I both told him he had a lack of 
reverse DNS. This email was asking various questions to ponder as what he 
stated was just not working.

I brought up using the ISP as secondary mainly due to the fact he might not 
have the ips actually assigned to him.  My system is set up somewhat the 
same as his.  I do NOT run my own DNS though.  I can send email to AOL via 
various email addresses.  My email is configured to use the SMTP server 
associated with the domain from which I am sending from.

We were spending all our time looking at the DNS.  The only place he was 
having a problems sending to was AOL.  I was begining to wonder if we 
really had a DNS problems or an email configuration problem

Fine, but do you have a real answer as to why he can send email to everyone 
he wants except AOL?
