My experience in this game was that you could create mail.xyz.com and point it to their IP as an A record, and point MX at this - no problems.
So long as the host had a valid and matching forward/reverse DNS entry there was no grief.
The issue was where there was no matching A/PTR set, this would increase the likelyhood of a spam host or something... right?
Or is it now a case of A/PTR must match the MX?
