Dr. Tom; this may cause problems as per Internet standards, you can not
have more than one server per Public IP address. Example, if you have 2
mail servers behind 1 IP address, the records for that IP (PTR) and for
the mail servers (MX and A) will not all match up. This is cause for
blocking by AOL and will cause test failures on other anti-spam
programs.
