I noticed several replies and haven't really been keeping up with the thread, but at this point, Yahoo is complaining because your mail server 'smtp.colwest.com' does not have a reverse DNS entry. > > I sent messages to my i70west.net and i70west.com accounts successfully back > and forth.

Alot of mail servers use this check to cut down on the spam, but still alot of others do not. So you would still be able to send mail through the severs that do not check. Hope this helps.
