For information: yesterday we rejected
117,119 for "HELO localhost"
35,427 for HELO with our own hostname
10,940 for HELO with our own IP address (and without [ ] too!)
4,629 for "HELO friend"
3,771 for HELO with our own mx name "columbia.edu"
So you can see roughly how popular each error is. The localhost ones
were all or mostly prescription drug spam.
There were a total 535,839 rejected using Mimedefang.
