Zitat von "Dave Buchanan (Abo Ltd)" <[EMAIL PROTECTED]>:
Dear postfix users
I have re-configured our postfix mailservers to remove catch all
aliases to remove the ammount of mail accepted.
I know have one more issue to resolve with respect to non delivery
notifications - backscatter
the setup is as follows
[EMAIL PROTECTED] -> [EMAIL PROTECTED] (demon.net is an uk isp)
This is what happens to an e-mail that has spam / virus etc from
Mail is accepted by our servers for delivery and then passed on to
[EMAIL PROTECTED]
The demon.net mailserver rejects this mail with a 550 error
our mailserver then sends a non-delivery notification to the sender
Never forward mail to destinations which don't accept it. Force the
users to get a clean forward target eg whitelist your server or cancel
the forwarding.
Regards
Andreas
