Hi,
 
In the current version of SM, I have a blacklist entry blocking SMTP traffic from 74.81.69.0 - 74.81.69.255 that I added on 11/1/14.  Yesterday in the SMTP log file, I saw numerous successful connections from this range similar to:

Hi Ben.  I've just tested this functionality with SmarterMail 13, and Blacklisting was working as expected.  I tested using single IP addresses and also using IP ranges.
