Hi,

exim is returning this message to my app server when sending emails:

Server response: 451 The server has reached its limit for processing requests from your host.

I already added the app server IP to WHM > Exim Configuration Manager > Basic Editor > RBLs > Whitelist: IP addresses that should not be checked against RBLs

I need to whitelist the IP, but this doesn't work.

Any ideas?

Thank you

Hi, thanks for your reply.

The problem here is that I don't want to increase the max smtp connection but whitelist the IP so that there is no limits.

The RBL rule is not what produces that error message. Instead, add the IP address to the following access list:

"Trusted SMTP IP addresses"

Thank you.
