Is this documented anywhere? First I've heard of it. Looking at the
ESMTP RFC 1651, the first example is
8. Usage Examples
(1) An interaction of the form:
S: <wait for connection on TCP port 25>
C: <open connection to server>
S: 220 dbc.mtview.ca.us SMTP service ready
C: EHLO ymir.claremont.edu
S: 250 dbc.mtview.ca.us says hello
...
Note the lack of "ESMTP" in the greeting...
If you want it in your banner, you can have it by setting the
smtp_banner option appropriately.
