smtp issues: progress indicator and gracious failure

[emacs user]

hi all,

These aren't bug reports, but more like feature requests, in the hope
that these features already exist and I dont know how to activate
them.

I use vm with smtpmail to send mail.  when on a slow wireless
connection, sending 20Mb attachments can take over 10 minutes.  I am
wondering if there is a way to get some progress indicator, such as a
continuously updating "percent uploaded" in the echo area?

also, smtp fails quite often, and then I am left with the outgoing
mail buffer.  I can press c-c c-c to try again and that works in most
cases, but then it adds the message to the outgoing folder again, so I
need to erase the .FCC line by hand.  wouldn't it be good if a failed
message was automatically put in "outgoing folder" such as a queued-
mail directory, and then sent at a later time?  perhaps when smtpmail
is called again to send another message?

cheers, E
