Yes and note we have semantics for increasing but not lowering.
However, check this out:
http://www.securityfocus.com/infocus/1654
According to this recommended setup, the allowed effective limits are:
EHLO 65 (71 - 6)
HELO 65 (71 - 6)
MAIL FROM 254 (266 - 12)
RCPT TO 256 (266 - 10)
NOOP 32 (38 - 6)
This is so bad.
What "bugs me" is the only reason they even suggest increasing NOOP to
38 is to cure mail delivery problems with their own Exchange servers
who are "padding NOOP." Well, what about the rest of the world?
