My IP is blacklisted under ATT - DNSBL:RBL

@adam_buyer , have you followed the instructions in the rejection message, i.e. to forward that message to abuse_rbl@abuse-att.net ?

When writing:

1. Include a rejection NDR verbatim
2. Write an e-mail that looks like it was written by a human, not auto-generated by some SPAM bot
3. Mention when this issue started (if you've been able to send e-mail before)
4. Discuss your history with the IP: how long you've had it, any situations where you may have allowed spam and how you corrected that issue so it no longer occurs
5. Aver your commitment to not allowing SPAM to be sent via your server
6. Do not use your e-mail server to send this e-mail.

If they haven't responded to your e-mail in 3-5 days, request an update... but no more often than every 3-5 days.
