Hello,  we recently had a customer forget their password and after trying more times than they should have they got blocked.  Typically if this happened in the past we just had them go to http://www.whatismyip.com and get thier password.  Recently Comcast along with other providers has started issuing IPV6 ip addresses.  When I go to the list of blocked ip addresses in Smarter Mail it only shows IPV4 addresses not IPV6 addresses.  So is Smarter Mail blocking IPV6 if so why aren't they listed in the block lists. 

 

Thanks.
