Hi,

The incoming emails from a certain domain name are straight rejected with the following message in the exim_mainlog:

xyz is in an RBL: Blocked - see SpamCop.net - Blocking List ( bl.spamcop.net )"

This is explained by the fact that I have "RBL: bl.spamcop.net " option enabled in the EXIM configuration but at the same time sender's domain name is in the whitelist of the receiving domain on my server. Does that mean that the whitelist is not taken into the consideration in this case?

Is there any solution to this?

Regards

Mike

The RBL check happens at SMTP time, so SMTP will reject it before your whitelist even gets a chance to take a look at it.

I've encountered similar in the past.
The only way I know around this is to disable the RBL for a few days until that domain gets delisted.

if xyz is getting blocked by you, then it will also be being blocked by many other mail servers, so they will find out sooner rather than later that something is wrong.
Maybe you could bring this to their attention.

Agree - alternatively, you can do a dig domain.tld mx and type in the MX ip addresses in the "Whitelist: IP addresses that should not be checked against RBLs" field. One IP per line.
