Many people prefer to use LMTP for delivery from postfix for better

sieve_vacation_dont_check_recipient = yes which violate Sieve
standard and cause auto-replyies sent to messages that should not
happen. Or abandon LMTP. or abandon postfix??
So while feature request is stalled are there any realistic
workarounds?
add to smtp_recipient_restrictions, before permitting email but after
all checks:
check_recipient_access pcre:/etc/postfix/recipient_access.pcre
# cat /etc/postfix/recipient_access.pcre
/(.+)/ prepend X-Original-To: $1
Warning, do not do this unless you don't mind recipients of
multi-recipient emails to see a list of everyone who got a copy of the
email message, including BCC recipients. This isn't a good solution if
you want to respect user privacy.
