      hey jawns, great question. I'm Giri Sreenivas, co-founder and CEO of Helm.   
      To answer your question, ISPs block port 25 and email service providers   
      typically reject emails coming from residential IP blocks.   
     "   
      
   If you read the thread, you get some idea what restrictions   
   ISPs put on their service. If they do not succeed at spam control   
   in this way, they are put on block tables and the problem is   
   solved that way.   
      
   1) The Port 25 thing does not appear in the TOS or AUP.   
   2) The feature is automatic and everyone does it.   
   3) If you phone tech support at the ISP, they will deny they do that.   
      
   And the people who seek to spam the email system, they know all this.   
      
   That's why it was funny, when a poster in the newsgroup I used   
   to hang out in, documented all of this, the changing port numbers,   
   the port automatically closing for 15 minutes and opening again.   
   All so he could spam his "newsletter" (and failed).   
      
   The ISPs do other things. I used to get port-scanned occasionally   
   (it would even show up in the router log, with a fancy technical   
   name for the detection). Today, I haven't seen a port scan (even   
   from someone else at my own ISP). All that stuff seemingly filtered   
   somehow (and that might not be a DPI doing that, I don't know   
   the technical means).   
      
   One reason they don't want residential customers operating   
   servers, is the servers are poorly maintained and they   
   generate more trouble than they are worth.
