Intrestingly enough I suspect that this UGLY (but workable) route was
probably machine generated at the gateway between the the Usenet
newsgroup 'comp.protocols.ibm' and the mail based equivalent.  BTW I think
that there are 2 gateways between this newsgroup and the mailing list as
most messages appear to be duplicated in the newsgroup.

My outgoing mail is addressed from either scw@ollie.seas.ucla.edu or
scw@seas.ucla.edu (and very rarely scw@cs.ucla.edu) depending on where
I sent it from.
Here are the headers just as I send it.
