CISCO fixup mode is an amazing technical achievement.
It will XXX server words not on a whitelist (and as the "A"
at the end demonstrates, it does this close to perfection).
It will XXX client commands not on a whitelist, as well as whitelisted
commands that span a TCP packet boundary (this is known to happen
with ESMTP command pipelining).
