Not only "been there, done that", but "am there, doing that".

We admin the server for a list in which one person sends out a weekly
post.  Subscriber base is about 14,000 people, with around 2000 of those
subscribers using Yahoo boxes.

"Excessive" bounces trigger automatic unsubscribes.  Although Yahoo
readership accounts for 14% of subscribers, it's not uncommon for 98% of
automated unsubscribes to be Yahoo-based... followed by Yahoo-using
people sending list-admin requests asknig why they were dropped, and
wanting to sign back up.

Following URLs in Yahoo's 4xx codes gives virtually-useless information.
The easiest fix to date has been for people to use less-presumptive
email services.

Sending mail to spambait addresses is a great way to get blocked.
Ditto for broken OOO autoresponders and foolish AV software backscatter.
