multiple gmail accounts: smtp and expiry

multiple gmail accounts: smtp and expiry

[George McNinch]

Hi,

To the extent that this is useful, I thought I'd share some
idea(s)/solution(s) to issues related to smtp and expiry for multiple
gmail accounts in gnus.

* expiry

I want expired mail from a gmail account to expire to the "correct"
[GMail]/Trash folder(s) for the account.  After some pondering, the
following seems to work. I'd be interested in alternate suggestions,
though.

Suppose that I have two gnus imap groups corresponding to gmail
accounts:

nnimap+gmail1
nnimap+gmail2

Use the following to create the per-group "expiry targets".

;----------------------------------------
 (setq gm-gmail1-expiry-targets
       (list (from ".*" "nnimap+gmail1:[Gmail]/Trash"))
 
 (setq gm-gmail2-expiry-targets
       (list (from ".*" "nnimap+gmail2:[Gmail]/Trash"))
       
 (defun gm-gmail1-expiry-target-function (group)
   (setq nnmail-fancy-expiry-targets gm-gmail1-expiry-targets)
   (nnmail-fancy-expiry-target group))

 (defun gm-gmail2-expiry-target-function (group)
   (setq nnmail-fancy-expiry-targets gm-gmail2-expiry-targets)
   (nnmail-fancy-expiry-target group))
;----------------------------------------

Now use gnus-parameters (or group parameters, or topic parameters)
to connect the expiry functions:

;----------------------------------------
 (setq gnus-parameters
  '(
    ("nnimap\\+gmail1.*"
     (expiry-target . gm-gmail1-expiry-target-function)
     )
    ("nnimap\\+gmail2.*"
     (expiry-target . gm-gmail2-expiry-target-function)
     )
 ))
;----------------------------------------


I guess my feeling is that it might be better (??!) if
nnmail-fancy-expiry-target(s) could also qualify expiry targets based on
the value of group, rather than just based data found in the header of
the article. But this might be unwieldy for reasons I haven't thought
of...and anyhow the above seems to do the job.

* smtp

I wanted to be able to adjust the smtp-user via gnus-posting-styles --
e.g. so that "sent" mail automatically ends up in the 

[Gmail]/Sent

folder of the correct gmail account.

One solution is to adapt some code found here

   http://emacswiki.org/emacs/MultipleSMTPAccounts

as follows.

;----------------------------------------
(eval-after-load "smtpmail"
  '(progn
     (defun smtpmail-get-and-delete-smtp-user-from-header ()
       "Find header field X-SMTP-User and if found return value as
         string and delete header field. If a header field of this
         name doesn't exist, return nil."
       (save-excursion
	 (goto-char (point-min))
	 (save-match-data
	   (let ((smtp-server))
	     (loop until (or (eobp) (looking-at "^[ \t]*$"))
		   if (looking-at "X-SMTP-User[ \t]*:[ \t]*\\(.*?\\)[ \t]*\n")
		   return (prog1 (match-string 1) (replace-match ""))
		   else
		   do (forward-line 1))))))
     
     (defadvice smtpmail-via-smtp (around set-smtp-user-from-header activate)
       (let ((smtpmail-smtp-user (or (smtpmail-get-and-delete-smtp-user-from-header)
				       smtpmail-smtp-user)))
	 ad-do-it
	 ))))

;----------------------------------------

Now just do something like

(setq gnus-posting-styles
  '(    
    ("gmail1"
      ("X-SMTP-User" "gmail1-user")
    )
    ("gmail2"
      ("X-SMTP-User" "gmail2-user")
    )
   )
)

(or add the relevant lines to existing defn of gnus-posting-styles...)
to insert "X-SMTP-User" headers temporarily in the mail for consumption by
smtpmail-via-smtp when sending the mail.

best,
george

Nice.

If I may be bold enough to request, why don't you put this up in
emacswiki?  All I did for GnusMSMTP link in wiki was simply write down
stuff similar to way you'd done here.  It took me 10m to figure things
out on the wiki.

And if people have better ideas, they'd correct it on the wiki.

Except in reality they don't. Mutiple smtp accounts has numerous
solutions - some which do and some which dont work with multiple gmail
accounts and the latest Gnus and for someone not familiar with elisp to
a high level its pretty complicated. Thsi issue has been here for a
while, the fact its raised regularly is proof of the pudding, and I
believe the developers intend to get Gnus working with multiple smtp
accounts from the base gnus using the authinfo files at some
stage. Perhaps already done - I dont know.

True.  You at least know what didn't work.  :-)

In addition the msmtp solution is not nice since (a) its external to
emacs/gnus and (b) passwords are kept in clear text as opposed to the
much more preferablie .authinfo.gpg. Possibly there is some cleaver way
around that but I dont know.

Again true!  But If I had smtp, gmail accounts and all the knickknacks
working in Emacs, I wouldn't have gone on to looking at msmtp?
