I think smtpmail is a make-shift solution for sending mail from client 
machines.  You might try experimenting with msmtp, which is a native 
program that implements the SMTP protocol for your machine.  Here is the 
link to the msmtp page:

You could try the patch below.

Do you happen to know why?

That seems to be specific to VM, so I'll let the VM crowd handle it.

thanks, fantastic!  what version of emacs can I apply this patch to?
I tried trunk and it failed, although I may have done this
incorrectly.  cheers, E

It's meant to be applied to `trunk' and seems to apply fine for me.
Here it is again, freshly regenerated from trunk, and bundled up in
a MIME attachment.

Well, it is not really a VM thing, except to say that VM is still using 
mail-mode for sending mail, which is semi-obsolete.  mail-mode puts FCC 
headers in the message composition buffer and leaves them there until 
the message gets sent.

Perhaps moving to message-mode will cure the problem?

Uday

Sounds like we have a bug there, then.  I guess "emacs user
<user.emacs@gmail.com>" should M-x report-emacs-bug about it.

I wouldn't know.

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

There should be a "*trace of SMTP session to HOST*" buffer, where HOST is
smtpmail-smtp-server.

I used to use smtpmail under VM, and added this to my ~/.emacs:

(defadvice smtpmail-send-it (around display-trace-buffer activate)
   "If an error is signalled, display the process buffer."
   (condition-case signals-data
       ad-do-it
     (error (shrink-window-if-larger-than-buffer
	    (display-buffer (get-buffer (format "*trace of SMTP session to %s*"
						smtpmail-smtp-server))))
	   (signal (car signals-data) (cdr signals-data)))))
