Postfix | get the original rcpt to into your header

You have a cascade of postfixes and aliases your mails are traversing through and are losing the original recipient address?

Simply add a header line with first servers postfix.

Tune your main.cf and add something like the ‘detect_recipients‘ line here:

smtpd_recipient_restrictions = check_recipient_access regexp:/etc/postfix/specials/denied_recipients,
check_recipient_access regexp:/etc/postfix/specials/allowed_recipients,
check_recipient_access regexp:/etc/postfix/specials/detect_recipients,
check_recipient_access regexp:/etc/postfix/specials
permit_mynetworks,
reject_unauth_destination

Your detect_recipients file:

/^(.+)$/ PREPEND X-Original-Rcpt: $1

This will add a header line.
