Sorry, I tried to reply, but I got an Earthlink opt-in to send mail. As
an Internet engineer, I won't register with that sort of blocker -- it
is a terrible technical technique that gives false security, and will
paralyze email if it becomes widespread.

You might suggest to Earthlink, your ISP, that they might be bright
enough to write software that notes the addressee of your outgoing
email, and automatically puts that into a whitelist.
