Disabled RBL for external authenticated SMTP clients

« on: February 03, 2012, 08:30:06 PM »

Hello,
I have an external user that cannot send through our email server because his sending IP is on a block list. This IP address block is allocated to a major cell carrier in the United States. Is there any to configure the server to not run spam checks against users that are properly authenticated and connected over SSL on port 465?

@400000004f2c340239ec6c2c 1481 dispatching RCPT TO: <XXXX@XXXXX.YYY>
@400000004f2c340239ec77e4 1481 logging::logterse plugin (deny): ` XXX.XXX.XXX.XXX 235.sub-XXX-XXX-XXX.XXXX.YYY [10.241.252.30] <XXXXX@mydomain.com> dnsbl 903 http://www.spamhaus.org/query/bl?ip=XXX.XXX.XXX.XXX msg denied before queued
@400000004f2c340239ec8784 1481 delivery denied (http://www.spamhaus.org/query/bl?ip=XXX.XXX.XXX.XXX)
@400000004f2c340239ec8f54 1481 550 http://www.spamhaus.org/query/bl?ip=XXX.XXX.XXX.XXX

Disable the Spamhaus RHBL list.

You can (yourself) also request spamhaus to remove the IP from their list and/or request the mobile carrier technical support to request spamhaus to remove the IP from the list.
No guarantees but it is possible.

Thanks for all your suggestions. The problem turned out to be that the client wasn't actually authenticating. After I set to the client to alway use username/password when sending, it started working correctly.
