Hi Maurice! :-)

Note that it says "may be", there is no absolute requirement for
this. In fact it goes on to say that an eight character hex number is
*only* okay if it is unique over a three year period. Plus nothing in the
working forbids spaces in the "serialno" field.

It also doesn't specify that the "origaddr" should be a Fido
address, because then they wouldn't need to allow quoting in case there
were spaces in there.

This standard isn't strict enough to allow any software making wild
assumptions except from the one that there'll be one space somewhere in the
middle of the MSGID. :)

Apart from that, the claim from that SBBS (was it that?) author that
repeating the same hex number in different casing makes a MSGID somehow
*more* unique is clearly bogus - if both numbers are always the same.
