SMTP Auth priority over RBL

Stewart -

PROBLEM
I want to exclude users who are logged in via SMTP auth from being checked by blacklists.

ENVIRONMENT

  • On-Premise Server + WebMail Installations: Version 6.0 > Current Version

CAUSE
You may want to set SMTP Authenticated accounts as excluded in blacklists. To do so, please do the following:

RESOLUTION

  1. Open and edit /usr/local/atmail/mailserver/configure.
  2. Find this block:
    #
    deny message = Rejected message because $sender_host_address is in a black list at $dnslist_domain
    hosts = !+relay_from_hosts
    dnslists = zen.spamhaus.org:b.barracudacentral.org
    #
  3. Before this block, add:
    accept authenticated = *
  4. So that the Exim block looks like this:
    accept authenticated = *

    #
    deny message = Rejected message because $sender_host_address is in a black list at $dnslist_domain
    hosts = !+relay_from_hosts
    dnslists = zen.spamhaus.org:b.barracudacentral.org
    #
  5. Save changes and restart Atmail.
    % /etc/init.d/atmailserver restart
  6. This will exclude all accounts set via SMTP Authentication.
