This guess would be very wrong. reject_non_fqdn_helo_hostname (you
are using deprecated syntax) is the single best low-cost antispam
weapon in the arsenal. When I have checked, it seems to block around
25% of all connections, and no known problems from using it.
Of course, I use it right. If I was going to have client submission
on the same port, I would precede it with the appropriate permit_*
restrictions as needed.
You might also benefit from consolidation of your restrictions into
smtpd_recipient_restrictions. It's easier to understand what's going
on that way.
