You can get around this issue if you are correctly doing mail submission
on port 587, and mail relaying on port 25. Something like the below maybe
(untested) :

rfc1413_hosts = ${if eq{$interface_port}{25}{*}{! $sender_host_address}}

$interface_port was deprecated recently for another variable although I
can't remember what it is off the top of my head. See documentation.
