Can a PTR record have a different IP as the MX record?

Hello,

I hope someone can help...

I noticed that AOL does not allow emails without a reverse mapping in
the zone data.

My mail server is on a different IP (different physical location) from
my web site which emails to clients from it's own SMTP server.

Can I just insert a PTR record with the IP of SMTP server? Will that
work even though it is different than the IP of the MX?


Thank you in advance,
paul
