Yahoo SUCKS! (part 2)

Of course I am not the only one with that problem with Yahoo:

Yahoo Bulk Folder
Bulk Mails
Company email entering to BULK folder of yahoo
E-mails Sent into Bulk Folder
and many many more

And all this from one for the main sources of SPAM on the Internet!
A service provider that is blacklisted all the time!

For example right now their servers 209.191.87.84 - 98 (atleast those 14) are blacklisted from spamcop, spamhaus, openrbl, sosdg and I am sure many more!
