Sorry! :-( Sorry! Sorry! I'm sending this with the whole "history" of our conversation.it is my opinion backed by dealing with DNS and email for many years facing all problems left and right we never had because the strict policy here that one IP has only one PTR what "official bad practice" do you need when you can see the problems otherwise would not be possible at your own?In the sense: "`best current practice' says something opposite". BTW: Are we talking on multiple PTRs for mail servers only or multiple PTRs in general?
well, in fact mailservers because for other services PTR's are not that important or verified at all - if they are not verified why bother about it?
but what would you gain by having multiple PTR records at all for whatever server? that's in fact the only relevant question
