i`ve started to watch all my users (3000+) and their list activities,

they always use do-not-reply as reply to adres which is valid.

then i whitelisted their mailings and lists,

afterwards i block all messages with that reply to header.

you need a postfix machine behind logsat to sniff them out using the scattermail option.

it is a heavy job nowadays to be a postmaster

All,

Anybody have any bright ideas on how to stop messages with headers that look like this:

Reply-To: "lkent21@hotmail.com" <mtipps@satx.rr.com>

Where there is obvious conflicting info in the reply to field?
