Postfix.IPv6.Unauthorized.Mail.Relay

description-logoDescription

This indicates a possible attempt to exploit a vulnerability in the way Postfix handles the relaying of e-mail messages.
In certain configurations Postfix becomes an open relay for mail addressed to an MX host with IPv6 addresses. An attacker can bypass e-mail restrictions and perform mail relaying by sending mail to an IPv6 hostname.
