I have one or two accounts that send few emails, but they
          have their home machines polling their account on my servers.
          I see them 'sending' thousands of messages and it's because of
          this. It would appear the counter clicks on the start of the
          send and not a complete message, so that aborted messages are
          counted for at least the purpose of g_user_send_ip.

          Sorry I don't see that this creats a real issue, perhaps
            I'm missing something? 
          These log entries are normal and unless something has
            gone wrong with a client will at worst double the
            g_user_send_ip you need. 
          If a client is genuinely looping then certainly the limit
            will block it, and that's probably good as it will alert you
            that the client software needs unjamming...

          After reviewing my logs again this morning I notice I
            have a few 
          Domains 
          that I receive the following errors from quite
            frequently. I had a 
          different domain reach the 1000 message "g_user_send_ip"
            MAX this 
          morning. 
          No DATA command sent 
          No DATA command sent-rset 
          Has anyone else had issues with this? What steps can I
            take to help 
          mitigate this problem for my end users? I don't want to
            keep 
          increasing 
          the "g_user_send_ip" limit because that is not a real
            solution. 
          Any thoughts on this would be great. 
          Thank You
