Do Address delimiters have an issue with this? I thought they did.
That is, u...@example.com sends and email "from" user+delimi...@example.com and
smtpd_reject_unlisted_sender rejects the email?
smtpd_reject_unlisted_sender (default: no)
Request that the Postfix SMTP server rejects mail from unknown sender
addresses, even when no explicit reject_unlisted_sender access
restriction is specified. This can slow down an explosion of forged
mail from worms or viruses.
An address is always considered "known" when it matches a virtual(5) alias or a
canonical(5) mapping.
• The sender domain matches $mydestination, $inet_interfaces
or $proxy_interfaces, but the sender is not listed in
$local_recipient_maps, and $local_recipient_maps is not null.
• The sender domain matches $virtual_alias_domains but the
sender is not listed in $virtual_alias_maps.
• The sender domain matches $virtual_mailbox_domains but the
sender is not listed in $virtual_mailbox_maps, and
$virtual_mailbox_maps is not null.
• The sender domain matches $relay_domains but the sender is
not listed in $relay_recipient_maps, and
$relay_recipient_maps is not null.
I interpreted that to mean that in all the bulleted cases, the mail would be
rejected by smtpd_reject_unlisted_sender.

Apple broke AppleScripting signatures in Mail.app, so no random signatures.
