Kind of OT: guess what I found!

Hmmm - we recently made changes to the method used for modifying the
Message-ID; however something appears to be mangling it.  The actual
Message-ID is sent as:

<EMEW,l1KAsk0c15677e2728c1a4bcf90ab66afb3922,,499FDD6E.9030908 at>

e.g. there are no spaces in the string (as you correct point out this
would not be RFC valid if there were spaces within it).

I've had several e-mail to my account directly from Jules and I've been
through all of them; none of the MIDs have any spaces in them either.

So something is mangling these on input to the list (MailMan??).  I'll
do some investigation and see if I can replicate this behaviour and see
if I can change the delimeter to something other than a comma.

Kind regards,
