[BlueOnyx:05868] Mackup mailserver

[Steffan]

Hello list,

I want to change my backup mailserver settings to prevent backchatter
I allready have a list of all e-mailadresses that the server needs to be relaying
But i cant figure out what i have to do to get it working

I added the adresses to the access file
TO:email at domain.com        RELAY

I tried with and without the TO:

But getting Relaying denied. Proper authentication required.

Does somebody know the right setup for this ?

Thanks Steffan
