Nevertheless ... I went looking for comments on how this was being done,
and found the following specualtion by a small number of different
people.
"SEF [is] unique in that it can detect what appear to be telnet
connections to Port 25 and drop the connection. This is probably because
telnet connections send one character at a time whereas real SMTP
clients send all the strings at once."
This would not require the 3WH, ISTM.
