Another problem is auto-responders, where commonly you specify a
blackhole or empty return path to avoid loops.
Not a user client.
check out RFC 6409 Sec 3.2 para 5 re NULL return paths.
Clients do commonly auto respond.
Yep, got that. And thanks, I'll add RFC 6409 to the list of RFCs on
the wiki. Done.
If client do send an auto-response with a NULL return path, do they
usually store a copy of that message on the server at all? I would
imagine they don't.
Actually I think they do. I've had MDNs turned off since dot, but I've
seen such messages in sent items folders before.
I also see from the KEYWORDS rfc (5788) that $MDNSent is registered
for the MDN purpose. It almost seems that a SENDMDN command is what
is indicated for this usage. Again, the "client can't screw it up"
philosophy.
sure. Gives the server the freedom to implement it the way they see fit
as well.
