AW: RBL checks when some mail is received via a relay

[Tim Cappell]

Hi,

No the relay is not whitelisted. As far as I understand, Mailscanner only queries RBLs for the last relay server which in this case is not blacklisted in any RBL.
To clarify my situation I'll try to visualize our current mail flow:

1) Domain.old: Sender -> mx.old -> mx.new with Mailscanner
2) Domain.new: Sender -> mx.new with Mailscanner

The problem is with part 1) of this setup, because all RBL checks are performed against mx.old which is a "good" server.
I would need a setup where Mailscanner uses "Read IP Address From Received Header = 2" for situation 1) and "Read IP Address From Received Header = no" for situation 2).
I don't know if this is possible so I'm also looking for alternate suggestions.

Tim

Why are the emails from this relay being trusted? Have you whitelisted it or something?

Mailscanner works fine for all the mails we receive directly but RBL checks do not apply to those mails sent via the relay (which is still about 50%). Thus there are a lot of spam mails that get through although the originating mail server is blacklisted.
