I would urge you NOT to do it this way. while the rfcs are a bit fuzzy on 
the issue, an SMTP server should have matching forward and reverse dns 
entries and many anti spam features make use of this.

I've been doing it for a long time and i am starting to see major 
ISPs and email providers(like Hotmail and AOL) do the same and reject mail 
when forward and reverse dns does not match. There is no reason why a 
legitimate mail server does not have matching dns entries.

Do yourself and all of us a favor and do the right thing; use a mail 
server that has matching forward and reverse dns matching.
