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
