[BlueOnyx:22830] Backscatter

[Colin Jack]

I know this is an old chestnut and I have tried to find solutions without success.

The problem is that we have long deleted email accounts on our servers that are still listed on the mega spam address lists.
So spam pours in – AV-Spam grabs some but lots still get through. An NDR then gets sent back to the poor b* whose email address is in the reply to.
Net result is we get listed as a backscatterer on RBLs. ☹

What is the suggested way forward on this?
