I noticed that there is an option smtp_banner that Postfix
has turned off by default.

# SHOW SOFTWARE VERSION OR NOT
#
# The smtpd_banner parameter specifies the text that follows the 220
# status code in the SMTP greeting banner. Some people like to see
# the mail version advertised. By default, Postfix shows no version.
#
# You MUST specify the $myhostname at the start of the text. When
# the SMTP client sees its own hostname at the start of an SMTP
# greeting banner it will report a mailer loop. That's better than
# having a machine meltdown.
#
#smtpd_banner = $myhostname ESMTP $mail_name
#smtpd_banner = $myhostname ESMTP $mail_name ($mail_version)

Is it possible to use this in a freeform fashion to contain a
message like this: "If this email is spam please notify the
postmaster at nospammyhost.dom, so that appropriate action
can be taken"

The idea is not to munge legitimate users email bodies (something
I wouldn't remotely consider for this)

Is this an interesting idea, or is another solution better,
to recommend a different default for virtual domains.

myhost.dom dummyvalue
postmastermyhost.dom adminuser
abusemyhost.dom adminuser
user1myhost.dom user1
myhost.dom catchalluser
