A general observation about a number of things: they need to be
done so that automatic parsing of control and log files *works*.
Thus, for example, placing the ? adjacent to the helo name is
wrong -- a ? is a character that might appear in the helo name and
there's no reasonable way to tell whether it did or did not. There
is a similar problem with spaces in names provided from the
outside; they allow the sender the potential ability to spoof
automatic checking. Among my "wishes" is that exim will simply
reject messages that have spaces in domain names in any place it
examines, logs, or otherwise manipulates.
