I guess the question is, is there anyway to block these invalid e-mail addresses at the Postfix level?
My biggest issue is because Postfix accepts the invalid e-mail address, it causes my upstream spamfilter to also think it is valid and thus creates quarantines for non-existent e-mail addresses.
I would like postfix to reply with a reject message like it does for other invalid e-mail addresses.
Maybe I should I post this in a Postfix support forum?
