I hope some solution to this problem with mailing lists is found.
Maybe mailing list software should evolve and take ownership of
the RFC5322.From header and put in there the list's own email
address while retaining the original poster's descriptive name?
I see (*) that mailman already has an option for the mailing list
address to take ownership of the RFC5322.From header (see "Hide the
sender of a message, replacing it with the list address" in section
"Spam-specific posting filters"):
http://staff.imsa.edu/~ckolar/mailman/mailman-administration-v2.html

(*) Although I'm not really sure if that is a Mailman general
feature, or some local feature implemented just in Aurora
University's installation of Mailman.

Also, I see that in the Mailman Wishlist it is said "Allow admins
to control and set individual headers, adding, removing, or
overriding those in the original message (sometimes very useful,
but could be dangerous!)":
http://www.gnu.org/software/mailman/todo.html

Therefore it looks like we are already half way there.

So, imagine a lists subscriber who sends email to a mailing list
with this RFC5322.From header:

   From: "Sam Spade" <[email protected]>

Then the mailing list software would rewrite the RFC5322.From
header when forwarding the email to all its subscribers to look
like this:

   From: "Mailman-Sam Spade" <[email protected]>

And now, imagine this behaviour becomes the default for the
majority of mailing list software...
and then have all out-of-office replies etc. being bounced back to the
list...

/rolf
Out-Of-Office replies are DSN and therefore should have a blank sender.

Tell this to Microsoft and have them fix their installed base of MS Exchange...
