You don't need and generally don't want to apply:
reject_unknown_recipient_domain
to inbound traffic on port 25. A brief glitch in DNS resolution of your
domain will cause you reject domains that you know to be yours.
Are you sure about this? I thought this only applies when the domain is
not local and docs indicate the same:
reject_unknown_recipient_domain
Reject the request when Postfix is not final destination for the recipient
domain,
It makes sense for 465/587, especially when sender is local/verified.
