This morning I found in my E-Mail 73viruses. In order to reduce my bandwidth consumption from this attack, I am taking the following actions:
- The "sending" E-Mail server must declare the size of the E-Mail, in advance (practically all do this, however the zombie spammers/virus ridden systems don’t).
- Any E-Mail over 30,000 bytes is rejected and the connection is dropped before it is even sent across the internet.
- Any particular IP address may only send me one E-Mail every 30 minutes. This restriction may be lifted after the current threat is reduced.
