Mail blocked by some domains

[mark]

Some domains have decided we're spam and are no longer accepting mail from us. This is a temporary situation, and I am working on getting in touch with the right people to make sure we can get unblocked and deliver mail in a timely fashion.

Domains known to be blocking at least some of our mail:

sbcglobal.net
att.net
earthlink.net

It's kind of hit and miss. We have four IPs that we send mail through and they blocked two of them. The other two remain unaffected. Of the two blocked, I have managed to get one unblocked through their automated system, but the other is still blacklisted.

I'll post again when I know more. In the meantime, if you use one of these providers and are having trouble getting mail, you may wish to consider temporarily using a different email address for now.
