Frontier Also Uses Yahoo Mail and thus is Broken

Frontier has also contracted with Yahoo Mail, and Yahoo is refusing our mail for Frontier:

May 3 15:00:57 mail postfix/smtp[20420]: E17491994: to=<>,[]:25, delay=150175, delays=150143/0/32/0.01, dsn=4.7.1, status=deferred (host[] said: 421 4.7.1 [TS03] All messages from will be permanently deferred; Retrying will NOT succeed. See (in reply to MAIL FROM command))

That link redirects to:

Which provides the helpful information:

Sorry, the page you requested was not found.

We suggest you visit Help Central

… Help Central has not been the least bit helpful.  I would ask people to see this article:

We haven’t had any more problems with compromised accounts since the Thursday before Last, April 24th, yet Yahoo continues to block our e-mail, and since they are now providing e-mail for ATT/SBC Global and Frontier, this affects those providers as well.

I’d ask you folks, if you have a Yahoo, ATT/SBC Global, or Frontier account, please generate a support ticket and/or complaint there.  Please spread the word about Yahoo’s practices.  There has to be a better provider ATT/SBC Global and Frontier could contract with and actually get functional e-mail for their customers.
