I wonder whether if might be the "Message-ID" in Julian's emails?

Here are some of the headers.  The 'Message-ID' is wrapped ("folded" in 
RFC822 terminology), contains spaces, commas and a tab;  the tab is 
probably the result of the folding.  RFC822 suggests that 'msg-id' 
should be "<" addr-spec ">".  (As I read it, if its syntax wouldn't be a 
valid email address, then it wouldn't be a valid 'msg-id' either.)

Chasing down the syntax from there suggests that such a 'Message-ID' would 
seem borderline at best; my suspicion is that it is beyond the borders. 
Even if such a Message-ID is technically legal, the "be conservative in 
what you send" principle might suggest considering a revision.

(It happened to come to my attention for a different reason: a few weeks 
ago, something started very occasionally tripping some syslog-analysis 
stuff we do on the campus gateways (i.e. routinely on millions of emails). 
I had put it on the "get a round tuit sometime" list.  This discussion 
prompted me to look, and discover that the instances seem to be Julian's
