Does anyone know who to contact if you've been blacklisted by the Yahoo SMTP servers?

Right, I've tried postmaster@yahoo.com, abuse@yahoo.com, tech-contact@yahoo-inc.com. I got an auto-reply from the latter two, but that's all.

Summary for the archives: Thanks to all who responded. Derek Balling who reads tech-contact@yahoo-inc.com told me how to contact Yahoo:

+1-408-349-3300, ask for "Yahoo Mail Customer Care" from 9 to 5 PST. (-0800)

He also forwarded my mail to the guy in Y!Mail who handles these things, and suddenly things started working again ! ;) I did call Yahoo at the number above a bit later and they told me that if this happened again I should contact <ip_review@yahoo.com> Mike. -- "Only two things are infinite, the universe and human stupidity, and I'm not sure about the former" -- Albert Einstein.
