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
If the sender has been dreamed up by the spammer etc then they receive unwanted mail
I would like to know how to turn these non-delivery e-mails off in postfix
Don't accept undeliverable mail, then you won't have to bounce it.
abo.co.uk needs to have a list of valid users and simply not accept mail
it won't be able to deliver.
