The file +# SMTPD_ACCESS_README provides an overview. + +# The header_checks parameter specifies an optional table with patterns +# that each logical message header is matched against, including +# headers that span multiple physical lines. +# +# By default, these patterns also apply to MIME headers and to the +# headers of attached messages. With older Postfix versions, MIME and +# attached message headers were treated as body text. +# +# For details, see "man header_checks". +# +#header_checks = regexp:/etc/postfix/header_checks + +# FAST ETRN SERVICE +# +# Postfix maintains per-destination logfiles with information about +# deferred mail, so that mail can be flushed quickly with the SMTP +# "ETRN domain.tld" command, or by executing "sendmail -qRdomain.tld". +# See the ETRN_README document for a detailed description. +# +# The fast_flush_domains parameter controls what destinations are +# eligible for this service. By default, they are all domains that +# this server is willing to relay mail to. +# +#fast_flush_domains = $relay_domains + +# SHOW SOFTWARE VERSION OR NOT +# +# The smtpd_banner parameter specifies the text that follows the 220 +# code in the SMTP server's greeting banner. Some people like to see +# the mail version advertised. By default, Postfix shows no version. +# +# You MUST specify $myhostname at the start of the text. That is an +# RFC requirement.

With local +# delivery, it does not make sense to do massively parallel delivery +# to the same user, because mailbox updates must happen sequentially, +# and expensive pipelines in .forward files can cause disasters when +# too many are run at the same time. With SMTP deliveries, 10 +# simultaneous connections to the same domain could be sufficient to +# raise eyebrows. +# +# Each message delivery transport has its XXX_destination_concurrency_limit +# parameter.
