More on spamfiltering feedback

Al wrote a post commenting on my post from last Thursday on spamfilters talking to senders who are being filtered. I think his take on it is close to mine. I would point out that Google has a pretty opaque system and no feedback to senders, but a lot of people seem to think their filters are accurate and do a good job.
Overall, I think there is room for discussion and feedback between senders and recipients, but on both sides the goal needs to be improving the enduser experience.

Yahoo delays, part 3: Yahoo speaks

Yahoo is aware of the recent problems and have been working feverishly to fix them. A Yahoo employee posted to a mailing list earlier today, explaining some of the recent issues. The summary is:
1) The Yahoo delays are a result of a tighter spam filtering policy. The delays are the result of the system erroneously recognizing email as spam and deferring delivery. They do believe that retrying long enough will result in all mail being delivered to Yahoo recipients.
2) They have been continually making fixes to the system over the last few days and senders should see queues start to empty over the next few hours.
3) They believe the adjustments made will resolve the deferral problems. If you continue to see problems, you can contact them through the form at http://postmaster.yahoo.com/.
4) They are working to provide more self-serve information at http://postmaster.yahoo.com/ as well as timely service updates.

Affiliates: what is a company's responsibility

These can either be listings in some of the URL blocklists (either public or private) or escalations of IP based listings. In many of the cases I have dealt with affiliates, the affiliates have sloppy mailing practices or are out and out spammers.
Recently the FTC settled with Cyberheat over their liability for the behaviour of their affiliates. In this settlement Cyberheat is required to monitor their affiliates as follows:
