For that to happen, the remote server must have already sent six
unrecognised commands. Exim supports EHLO, so that's one possible bad
command gone. Any extensions should be enabled by a keyword given in
the response to the EHLO command. There's no reason otherwise for there
to be unrecognised commands. VRFY and EXPN do not return "Unrecognized
command", even if not available.
Exim allows a few mistakes, because humans who test mail-servers do make
typos.

It seems to have reached the point where a user of a GNU/Linux distribution
will consider themselves "hot" if they can install the system on their own and
do the same for others, or a "guru" if they once used a command-line shell.
