Yeah. You get a better spam score and a better rep for your server if the hostname you use as an MX record matches the reverse DNS for its IP address(es) as well and everything is correct as recommended by rfc docs. If there's outgoing mail it's all going to use the same hostname as the "ehlo" I.D. anyways, isn't it?
The big bosses and professionals are cracking down on servers etc., aren't they? I just recently tried to set up an alternate/backup server from a different provider in a very authoritarian country in northwestern/central Europe, but they borked my billing information terminated service and screwed up my domain renewal and caused a lot of other grief elsewhere in addition. Barely managed to save myself and stay online.
So we're going to see more small and medium sites kicked off the internet, and even having had one's own website and email means we're not welcome on FB, TWTR, and friends. Just squash the competition for interstate commerce, because the cartels are taking over.

Why aren't you just using a single domain as the MX record for all the domains? Then you only need one SSL cert pair for all of this, and if you publish the right SPF records, each domain can send from the same MX host as well.
