Yahoo Mail Spam Filters Block Efforts to Help Fight Spam

I was wondering if any one else has had this problem. Over the past couple of weeks I've had issues with Yahoo mail blocking my admittedly small efforts to fight spam. Every day I'd forward the messages in my spam folder to organizations like SpamCop.net, spam@uce.gov, and coldrain.net. However this past week or two I'm only able to forward maybe one or two messages a day before it started to block me from doing so with the following message:

Your message was not sent

Your account has been temporarily blocked from sending messages. This block can be caused by sending messages that trigger our spam filters, or by having too many recipients in one email. We encourage you to review the contents and recipient list of your message, and try sending it at after an hour or two. Doing so will usually resolve the matter.
If you are still unable to send messages after a 24-hour period, please read our FAQ for more information and to request Customer Care assistance.

We apologize for the inconvenience.

Thanks,

The Yahoo! Mail Team

Of course I've contacted "The Yahoo! Mail Team" multiple times and I've changed my password. So far nada and now the problem is starting up on another Yahoo mail account that I forward spam messages from.

This issue is especially problematic with SpamCop because after 24 hours the timestamps in the headers of the spam messages become stale and SpamCop won't process them, so I end up deleting most of them. It's a sad irony that my endeavors to help in this fight against spam are being thwarted by the very Yahoo feature that is itself trying to protect email users by identifying spam sources within Yahoo mail. While I totally understand the purpose of this effort and applaud the work being done; In my case it's overreaching and needs to be tweaked in some way. Possibly if the the application could look at the recipient email list to see if they're being sent to spam fighting organizations first before deciding whether or not to block the account.

Update (10/25/2010): After resolving the issue way-back-when the problem has re-appeared.

Update (4/4/2011): After throwing up my hands and giving up I tried again a month later and the problem went away completely. Now I have a new problem with Yahoo Classic. It keeps fouling up the send saying "There was a problem! Not sure why, but our usually-reliable server goofed-up while sending this message. Please try again." and I try again and it doesn't work. Or if it does get sent it will fail to allow me to delete the email saying "There's a problem viewing this message. Are you trying to access a message that's been moved or deleted? Try going to the folder it's in (e.g., Inbox, Trash) and selecting the message from there. If you've tried this, and relaunching Yahoo! Mail doesn't work either, feel free to contact Customer Care about Error Code 4."

Enterprise Extender PTFs Again

Once again the list of v5.4 Enterprise Extender recommended PTFs has left off some important patches. MF47274 & MF47275 can cause HPR-IP controllers to remain in an unusable VARY ON PENDING state, and varying them off and on again doesn't fix it.

Our lord Ib'm should have added MF47838 & MF47839 to the list. (Note that MF47838 supersedes MF47275). However there is still a problem because sometimes IPLing or restarting the system from a restricted state causes the controllers to again remain in a VARY ON PENDING state. Fortunately, this time it can be fixed by varying them off and then on again. Not a show-stopper, just an annoyance.

Ib'm support tells me there are two test PTFs that will resolve that problem too and they're in the process of granting me access to them. My advice to the users of HPR-IP controllers is to ignore MF47274, MF47838, and MF47839 until these test PTFs become available.
