How to get original recipient from Postfix when using LMTP?
Many people prefer to use LMTP for delivery from postfix for better efficiency but X-Original-to header support still missing after many years. One affect of this is need to set 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.pcrecat /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.

Bummer, I was actually glad to see a way to get the x-original-to when using LMTP.
Guess I'm stuck with the LDA until this gets implemented.
