Curioser & curioser...

I asked the user how he entered the address and he responded that he'd
copied & pasted between an old email into a new one.  Something else I
noticed when I got his reply was that the 'X-mailer:' entry was different.
In the first offending one the x-mailer was Novell Groupwise 5.5.3.  In
subsequent messages that reached me without problem the x-mailer is listed
as Internet Mail Service (5.5.2650.21).  I don't know if that has anything
to do with it.

I suppose I should note that this person's organisation sits behind the
Secure Gateway Enterprise which is basically a huge multi-tiered ISP for the
Australian Government.  As you may have noticed, I mentioned in my first
post that the problem message made no less than nine hops (7 of which
bounced around inside the SGE, with at least three Postfix installations)
before reaching me.  I know that intermediary mail servers aren't supposed
to add/change anything in the mail header but this makes me wonder.

Chazzozz!!
