Okay, that mostly answers my question :-)  I can now assume that there is no
hard and fast rule on this.  So I'll stop using "bar at gmail.com" in the
"From:" field and instead use Linkedin's second approach which is as follows:

...
From: Mr Bar via Linkedin <members at linkedin.com>
To: foo at gmail.com
Reply-to: bar at gmail.com
Sender: bounce at linkedin.com
...


Thanks everyone for the replies.

As for SPF, yes I have used it with "-all".  I have also used DKIM signatures
for the simple reason that Linkedin uses it.  Linkedin also uses Domainkeys [0],
but I dropped it as according to Wikipedia, DKIM supercedes Domainkeys.  The
result of all these is that NONE of the emails that are sent with
"From: bounce at example.net" goes to the Spam box.  But it was the
"From: bar at gmail.com\nTo: foo at gmail.com\nSender: bounce at example.net" thing that
caused the trouble :-(  It works for gllug, linkedin, and drupal.org.  So it
could be that there is something to do with the reputation of the domain.
