I have a business partner who sends mail from his Yahoo account in Europe.

Recently, his Yahoo mail server IPs keep getting added to Spamcop.

On my cPanel/WHM where my mail resides, his mail gets rejected because he is listed in Spamcop.

He contacted Yahoo, and they claim that my server is adding their mail server IP to Spamcop.
Is this even possible?

If so, where could I check to see if and why this is happening. I looked at /var/log/exim_rejectlog and I find a few lines where his messages are being rejected, but they are just indicating that his server is listed in Spamcop, not that his mail server is being added to Spamcop and/or why.

Is there a way to whitelist only his email address is WHM?

You could add his Yahoo IPs to the RBL whitelist in WHM > Exim Configuration Editor for this option:

Whitelist: IPs that should not be checked against RBLs

Tristan, there are quite a few Yahoo IPs that need to be added. The online help ([?]) does not say whether this list can take CIDR notation, and I suspect it cannot. Can you verify one way or the other?

I'd like to just RBL whitelist the entire Yahoo IP range in question: 98.136.0.0/14 If that is possible.

I'm not aware of the list taking CIDR notation, but I cannot say it doesn't either. I would suggest trying that to see the results. If it doesn't work, then you'll have to individually whitelist the IPs there. Exim itself does allow CIDR notation, but the WHM editor for the whitelist may not allow it based on prior discussions about that area.

Hi Tristan! Well, wow... looks like it takes CIDR! No errors when entering 98.136.0.0/14. Will watch, now, and see if it works! Thanks for the push to try it... did not think it would work!
