I have a virtual alias table like this exam...@my-domain.com exam...@other-domain.com
other-domain.com is not controlled by me, it could be gmail.com or hotmail.com if a sender some...@sender-domain.com sends an email to exam...@my-domain.com, postfix forwards this message correctly to exam...@other-domain.com. however, messages have been marked as SPAM by other-domain.com. I want postfix to rewrite this message's Sender as exam...@my-domain.com so that other-domain.com's mail server doesn't marked this mail as spam. did I set this up starting with a wrong way? if not using alias, what can I do to serve this purpose? My goal is to make exam...@my-domain.com as a masked email address. Thank you. Tony
