No, but you can use name in your e-mail address that is has CNAME record in DNS, e.g. "gmail.example.

If some list servers restrict posts to subscribers, any logic to treat addresses as equivalent would be in the list server, not Postfix, which just delivers the message to the list server. That's easy to understand. thank you. Keep in mind that there is no reason, or need for a MLM to try to see those addresses as equivalent, nor should it. It's up to the user to use the same address, or variant of address to post to the list that they used to sign up with. Google may see multiple variants as equivalent but that does not mean that other servers need do the same. Peter

Email RFCs say that the address localpart semantics are defined by the receiver, therefore Postfix does not assume that the following addresses resolve to the same mailbox: usern...@gmail.com usernam...@gmail.com user.n...@gmail.com Postfix also does not assume that the following domains are equivalent. gmail.com googlemail.com To signal domain equivalence, the receiver should use CNAME records or some other explicit mechanism.
