PR #6 has a DB view as part of SES enablement - where we need to ensure that we don't backscatter for reputation.
fyiorgnz/docker-postfix#4 is the counter-part issue for image changes required for postfix.
Closing this issue as it's effectively a duplicate of fyiorgnz/docker-postfix#4 and that'll hopefully get done as part of the postfix image improvements for fyi-next+1
Currently postfix checks email aliases match a regex, but not exact hashes. Rejecting invalid aliases at SMTP time would eliminate a lot of spam from holding_pen and also give authorities immediate feedback when they've mistyped an address.
Downside: some authorities seem to do a lot of manual copying of addresses between systems, which is where typos arise. They may give up instead of dealing with the hard bounce.
