m...@domain.tld has an alias al...@domain.tld and mail sent to alias. X-Original-To: al...@domain.tld prepends to the message. It's OK.
If the before-queue content filter enabled as shown below then X-Original-To: is m...@domain.tld. Why did this happen? I suppose it must be al...@domain.tld anyway. But if REDIRECT to other mailbox configured in header_checks (in addition to content filter) then X-Original-To: is al...@domain.tld as supposed. diff master.cf.bak master.cf 11a12,13
