RE: Back to Reverse DNS

Buck,

That actually makes perfect sense.  Most ISP's are configured the same way.

You usually do have to have your outgoing SMTP mail server on your ISP's
network.  Since most SMTP server are configured to relay mail from the
internal network but not the external network.

For example: 

Lets say my work email server is nuvox.net and I have a personal account
with cinci.rr.com.

In Outlook at work (Nuvox is the ISP) I'd have:
Work Email
  incoming: pop3.nuvox.net
  outgoing: smtp.nuvox.net
Personal Email
  incoming: pop3.cinci.rr.com
  outgoing: smtp.nuvox.net

At home (with Roadrunner Cincinnati as the ISP) I'd have the following:
Work Email
  incoming: pop3.nuvox.net
  outgoing: smtp.cinci.rr.com
Personal Email
  incoming: pop3.cinci.rr.com
  outgoing: smtp.cinci.rr.com
