I am not familiar with BASE so someone else will have to help you with that. Use tcpdump/wireshark/snoop etc... to capture one of those email sessions. (You can replay the traffic back into snort and see if you have the traffic in question that is giving you the alerts.) If you do have the traffic then open it in wireshark to view the entire tcp stream (use the 'follow tcp stream' option) and go from there. Hope this helps!
