fs-change-smtp and draft messages

fs-change-smtp and draft messages

[Hadron]

I have a problem with draft messages that I hope someone can help me
with.

If I save a message to drafts and then edit it at a later date (press
"e" - calls function gnus-draft-edit-message) then the call to the hook
fs-change-smtp doesn't respect the existing "from" field in the draft.

,----
| (defun fs-change-smtp ()
|   "Change the SMTP server according to the current from line."
|   (setq smtpmail-starttls-credentials '(("smtp.gmail.com" 587 nil nil)))
|   (setq message-send-mail-function 'smtpmail-send-it)
|   (save-excursion
|     (let ((from
|            (save-restriction
|              (message-narrow-to-headers)
|              (message-fetch-field "from"))))
|       (message "%s" from)
|       (message "**** From is `%s', setting `smtpmail-smtp-server' to `%s'"
|                from
|                (cond
| 		((string-match ".*adron.*" from)
|  		 (setq smtpmail-auth-credentials '(("smtp.gmail.com" 587 "hadronquark" "*******"))))
|                 ((string-match ".*default.*" from)
| 		 (setq smtpmail-auth-credentials '(("smtp.gmail.com" 587 "otheremails" "********"))))
| 		(t
| 		 (setq smtpmail-auth-credentials '(("smtp.gmail.com" 587 "default" "********")))
|                )))))
| )
| 
| (add-hook 'message-setup-hook 'fs-change-smtp)
`----

Despite the draft containing a field

"From: Hadron <hadronquark@googlemail.com>"

the "from" returned by message-fetch-field is another email address from
my address book. It is not getting the "From" field from the draft - or
doesn't appear to be.

This results in the smtp-auth-credentials being set incorrectly.

Any hint/tips on how to correct this?

The strange thing is that the from line above is the one displayed in
the draft edit buffer. It's only when I actually send the message are the
are the wrong smtp credentials used.

Sure, because the message buffer doesn't neet to be setup then.  You
added `fs-change-smtp' to `message-setup-hook', whereas
`message-send-hook' would be much more appropriate.

Ye gods. That must have been some careless global changes I made.

The question remains though and possibly you could explain it to me (I
cant follow the lisp), why is message setup hook being called for
editing a draft, and even though it is (was) why is it not picking up
the existing "From" field that is there in the draft?

I found this thread too where you recommend `message-send-mail-hook'
instead. Which would you say is better?

I just sent the other message here having saved it as a draft, closing
gnus and editing it upon reentry

The "From" field was perfect

However, the "To" field was missing although upon sending it, it found
its way to the correct group and also included the correct "face"
headers (I have two)

Interesting ;)

Ah, yes.  `message-send-mail-hook' is better because you don't have to
set any SMTP server when sending a news posting.

Via NNTP.

--8<---------------cut here---------------start------------->8---
RFC 977                                                    February 1986
Network News Transfer Protocol

3.10.  The POST command

3.10.1.  POST

   POST

   If posting is allowed, response code 340 is returned to indicate that
   the article to be posted should be sent. Response code 440 indicates
   that posting is prohibited for some installation-dependent reason.

   If posting is permitted, the article should be presented in the
   format specified by RFC850, and should include all required header
   lines. After the article's header and body have been completely sent
   by the client to the server, a further response code will be returned
   to indicate success or failure of the posting attempt.

   The text forming the header and body of the message to be posted
   should be sent by the client using the conventions for text received
   from the news server:  A single period (".") on a line indicates the
   end of the text, with lines starting with a period in the original
   text having that period doubled during transmission.

   No attempt shall be made by the server to filter characters, fold or
   limit lines, or otherwise process incoming text.  It is our intent
   that the server just pass the incoming message to be posted to the
   server installation's news posting software, which is separate from
   this specification.  See RFC850 for more details.

   Since most installations will want the client news program to allow
   the user to prepare his message using some sort of text editor, and
   transmit it to the server for posting only after it is composed, the
   client program should take note of the herald message that greeted it
   when the connection was first established. This message indicates
   whether postings from that client are permitted or not, and can be
   used to caution the user that his access is read-only if that is the
   case. This will prevent the user from wasting a good deal of time
   composing a message only to find posting of the message was denied.
   The method and determination of which clients and hosts may post is
   installation dependent and is not covered by this specification.

I got smtp authorization errors when using message-send-mail-hook.

None for message-send-hook

No idea why.
