Antispam Group Outlines Defenses to Block Botnet Spam
A major antispam organization is pushing a set of new best practices for ISPs (Internet service providers) to stop increasing volumes of spam from botnets.
The guidelines, from the Messaging Anti-Abuse Working Group (MAAWG), were drawn up at a meeting in Germany last week and deal with forwarded e-mail and e-mail that is sent from dynamic IP (Internet Protocol) addresses.
Many people forward their e-mail from one address to another, a relay that goes through their ISPs mail server. But many ISPs use automated tools that could begin blocking further e-mail to an address if a large volume of e-mail has come through. Legitimate messages would be blocked, too.
