View Full Version : Reject forged/spoofed email addresses

9th November 2010, 03:45
Many people have been asking how to block forged MAIL FROM:<> email addresses.

Correct me if I wrong but it seems to me that Postfix:reject_unauthenticated_sender_login_mismat ch could resolve this issue for all local addresses. If so I could see integrating this into ISPC3.

You can read up on it here (http://www.postfix.org/postconf.5.html#reject_unauthenticated_sender_logi n_mismatch).

It is my understanding that if used with smtpd_recipient_restrictions it will require you to be authenticated for any addresses located in $smtpd_sender_login_maps & that can be easily specified.

Here is another post with a similar dilemma.
