[BlueOnyx:26342] Re: Backscatter / user not found bounce

[Colin Jack]

Hi Michael and Ken,



Colin: Do you by chance have a mail relay in front of your BlueOnyx that

forwards the inbound emails to the BlueOnyx. Because *that* could be the

problem.



That is actually a very valid point.

I need to check through the effected domains and see whether they are using a 3rd party filter.



Kind regards



Colin
