Yahoo Adopts Tougher Email Guidelines to Block More Spam

The New Yahoo Blocklists Powered by Spamhaus

We have just confirmed that blocklists used by Spamhaus, one of the most stringent anti-spam organizations active today, have recently been adopted by Yahoo.

What it Means

ISPs are free to filter email as they see fit and they've traditionally relied on their internal lists and tools to do so. By using Spamhaus, Yahoo has now added an "outsourced" filtering solution in addition to their internal mechanisms. Compliance guidelines at Spamhaus are very strict and they may require emailers to follow certain procedures, such as implementation of double opt-in registration.

Are You Affected?

As you may know, a "spam trap" is an email address specifically set up to attract and identify unsolicited commercial email. Any emailer who has a spam trap address in their database may trigger the Spamhaus blocklist, which will now affect delivery to Yahoo.com and Yahoo.biz addresses.
