    I'm having difficulties whitelisting for a 3rd party anti-spam server.

    Specifically, a client is using a service coming from spamh.com and i've added all the CIDR IP ranges to the access lists:
    Sender verification bypass IP addresses
    Trusted SMTP IP addresses

    And the domain here:
    Backup MX hosts

    Still, the host is being rate-limited when I turn on
    Ratelimit incoming connections with only failed recipients

    And I'd rather not have to disable that for just this one client.

    Most of the posts regarding the whitelisting of incoming, IP addresses seems to be outdated.

    Here's my recent (as of October 2016) versions:
    Cpanel: 11.58.0.31
    Exim 4.87

    Any help (or ideas) are greatly appreciated!

    Thanks.

    Hello,

    Could you open a support ticket using the link in my signature so we can review your system to see why this is happening? You can post the ticket number here so we can update this thread with the outcome.

    Thank you.

    It seems to work now. The is my current hypothesis and hopefully it's useful for someone or someone could verify this actually works:

    When I whitelisted the IP range in WHM ACL, it didn't work. (IP address was still blocking). This includes a restart of exim (but no reboot)

    - The logs still said "IP rate limited"

    - My theory is that something still tracked "X.X.X.X sent X e-mails in the last hour" and was ignoring the white-listing setting

    - So I disabled all the rate-limiting settings in WHM and let a flood of e-mails come through

    - Then I re-enabled the settings after a few minutes and now the whitelisting IP ACL settings work

    I'm not sure if the above actually helped, or if i randomly wiggled wires and coincidentally the issue resolved. :)

    Hello,

    I'm happy to see it's now working well. Regarding the workaround, you could also remove tracking data for individual domain names from the following locations if you don't want to wait for the existing cache to expire:

    Code:
    /var/cpanel/email_send_limits/track/
    /var/cpanel/email_send_limits/cache/
    Thank you.
