Can you clarify what you mean by "doesn't

forward-must-match-reverse, or something else like EHLO matching?
I asked Blair about this and he has clarified by pointing to the
official docs on the matter:
"The sending IP must have a PTR record (i.e., a reverse DNS of the
sending IP) and it should match the IP obtained via the forward DNS
resolution of the hostname specified in the PTR record. Otherwise, mail
will be marked as spam or possibly rejected."
