Re: Problems sending mail to yahoo?

FWIW:

I've been tempted to implement sort of a "reverse blacklisting".  If an
(MX|provider) trips a 4xx threshold, have the local MTA s/4/5/ on emails
to the problem (MX|domain).  If it trips a 5xx threshold, including
"upgraded" 4xx responses, simply refuse delivery altogether at the local
end.

"You don't like our email?  Fine.  You won't see it."

We've observed good success convincing people to switch away from
overly-draconian email providers... so a "reverse blacklist" might not
be as _Wolkenkuckucksheim_ as it seems.  Or, then again, it might. ;-)

DO NOT send mail to the following addresses:

Sending mail to spambait addresses is a great way to get blocked.
Ditto for broken OOO autoresponders and foolish AV software backscatter.
