I used to have a rule to reject any mail from my domain but which were
not originating from trusted machines nor authenticated users.

not tested here but something along the lines of:

match !from local mail-from "@opensmtpd.org" reject
match !auth from any mail-from "@opensmtpd.org" reject

there are other ways too

Filter email where sender and rcpt-to are the same

[Mischa]

Hi All,

There has been a new scam going around for some time now where you get an email 
from your own email address to your email address.
For people that don't know better it's scares the s**t out of them as the email 
is like:

Hey I hacked your account as you can see since I am sending this email from 
your own account.
etc..

Is there a quick way to filter email where the sender and rcpt-to are the same?
Has anybody created a filter already to easily do this?

Thanx!

Mischa
