I have been getting tons of bounces from one domain. The 'original' message always is FROM: some-one-differnet@domain.com
For example:
lar_ry@domain.com
vendor@domain.com
etc.....
But this is only happening to one domain in particular, which just happens to be the servers domain name (not used for anything else).
The bounce messages generally have the original message attached and it is always spam (get viagra.... pills... whatever).
Is this real spam that was sent to bad addresses and is being bounced back? Or is this a spammers new way of reaching customers?
Is there a way to check the outbound / inbound bandwidth for one email account?
