received_port. I use:
# We'll try and avoid RFC1413 lookups for client connections on
# the MSA and SMTPS ports. Ideally this would be done by setting
# rfc1413_query_timeout to zero for such connections. However this

rfc1413_hosts = ${if eq{$received_port}{SMTP_PORT} {*}{! *}}
rfc1413_query_timeout = 15s
