Bellsouth has started rejecting ALL OptiBoard emails with this false claim:

550 [PERMFAIL] bellsouth.net requires valid sender domain {need mx}

OptiBoard.com does have MX records as I tried to point out to them on July 22nd:

Your system is bouncing all emails from optiboard.com because of the false contention that there are no MX records for optiboard.com. Look it up. There are MX records:

10 optiboard.com.inbound10.mxlogicmx.net
20 optiboard.com.inbound20.mxlogicmx.net
20 optiboard.com.inbound30.mxlogicmx.net

Note: Mxlogicmx.net is my first line of defense against spam.

Please fix this. If you do not remove these false reports for optiboard.com then I will be forced to not allow bellsouth.net customers access to my sites and I would rather not have to be forced into that position. I'm sure they will not be pleased with this either. Thank you.

They have refused to respond. I believe the only way to get them to fix this is if the OptiBord Bellsouth customers contact them directly. The problem is that I am getting flooded with bounced emails and I can no longer afford to spend time deleting these emails.

If you are a Bellsouth customer, please contact them and ask them to fix this. If this is not fixed soon, then I'm afraid I will have no choice but to ban all bellsouth email addresses.
