According to stipulations filed yesterday Penkava and Yahoo! have agreed to go to private arbitration. This will happen before September 1, 2013. Also filed yesterday was an agreement that Yahoo! has until September 7, 2012 to respond to the complaint.
Spamhaus announced today they are publishing two new BGP feeds: Extended DROP and the Botnet C&C list. These lists are intended for use inside routers in order to stop all traffic to or from listed IP addresses. This is a great way to impact botnet traffic and hopefully will have a significant impact on virus infections and botnet traffic.
In other news I’ve been hearing rumbling about changes at Yahoo. It looks like they have changed their filters and some senders are feeling lots of pain because of it. It looks like senders with low to mid range reputations are most affected and are seeing more and more of their mail hit the bulk folder. This afternoon I’m hearing that some folks are seeing delivery improvements as Yahoo tweaks the changes.
In a post this morning, Dan Deneweth from Responsys says he’s received confirmation from Yahoo that they have increased the value of engagement metrics when making delivery decisions.
The really great thing, for the ISPs, about engagement metrics is that they directly measure how much a particular email is wanted by recipients. There’s no guessing about it, it measures how engaged the recipient is with a mail. Even better is the fact that, unlike proxy metrics, engagement metrics are extremely difficult for the sender to manipulate. As a sender I can artificially lower complaints and bounces without improving the mail I’m sending. But I can’t improve engagement metrics without actually engaging my recipients.
