^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

	This I do not quite understand. How do I learn what my reverse 
DNS is called? I do have an ip number but it's not static, it changes 
daily it seems. Once I find it how do you change it to another DNS? What 
can I read to learn...

	Thanks Bill. Your far more trained in IP things than I. But even 
I can see that AOL thinks my email is from a bogus smtp server behind a 
router and DSL modem. Most people with DSL modems are using their ISP's 
smtp server and that will work.
