I can't imagine AOL has a problem with this, but to "fix" it (the RFCs do not require
doing this) if you have virtual mail servers, you need to change the MX records for
those 50 domains so that they are all "mail.master_domain.com". For example:
domain1.com MX 10 mail.master_domain.com
domain2.com MX 10 mail.master_domain.com
domain3.com MX 10 mail.master_domain.com
...
and have the reverse DNS for 206.160.244.72 be set to mail.master_domain.com.
Of course, this nonsense isn't necessary according to the RFCs, and would only be
needed to help increase your chances of getting mail to AOL. It will have the
drawback of looking less professional for your customers (instead of having the MX for
"domain1.com" be "mail.domain1.com", it has to be "mail.master_domain.com").
