Hello,
Having some issues sending to Craigslist and trying to only bind email sending to one IP (mail.sgdesign.net -> 174.143.222.97).

Some older accounts used 174.143.222.100 so I have been running both.

In the Bindings area of Smartermail ALL the IPs I have on my server are being displayed. No problem I only set ports on the particular IP I want to use, and deleted them from the older duplicate (*.100). But,the *.100  IP is still being used for sending. Restarted the Smartermail Service, same issues.

Running Smartermail 16
Using IIS which is configured to the proper IP

Zone file has Reverse DNS for range catching both IPs:

v=spf1 mx a ip4:174.143.222.100/32 ip4:174.143.222.97/32 ?all

Anyone run into this issue and know how to solve?
