mailing to yahoo.com bounces

[http://dummy.us.eu.org/robert (robert)]

Last Friday, I started receiving bounces from yahoo.com

<http://www.yahoo.com/~globalremove2000>:
64.157.4.88 does not like recipient.
Remote host said: 553 VS10-RT Possible forgery see http://help.yahoo.com/help/us/mail/spam/spam-18.html (#5.1.1)
Giving up.

I'm wondering if other Spam Bouncer users are experiencing the same thing.
It says on the referenced web page to "Remove email addresses that
bounce".  Since I know that the Spam Bouncer generates a bounce when using
SPAMREPLY=COMPLAIN, perhaps Yahoo is blocking users of Spam Bouncer that
receive too much spam from yahoo.com ?  (How ironic!)

Thanks for any info.
