Password sending mail only once

Password sending mail only once

[Torben Knudsen]

Some time ago I was asked for a password when sending mail only the
first time in a gnus session.  Now I am asked every time I send a
mail.  

How can I get back to only given the password once?  

I prefer solutions with out storing password anywhere.  Given it once
is what I prefer.

I have found some info on the net but nothing I could handle with my
limited skills.

With emacs 23 I have the following set up:

,----
| ;; encryption stuff
| (require 'auth-source)
| (require 'epa-file)
| (setq epa-file-cache-passphrase-for-symmetric-encryption t) ;;VERY Important
| (if (file-exists-p "~/.authinfo.gpg")
|     (setq auth-sources '((:source "~/.authinfo.gpg" :host t :protocol t)))
|     (setq auth-sources '((:source "~/.authinfo" :host t :protocol t))))
| ;; no idea whats needed with mm2015 : the documentation is sparse
| (setq 
|       mml2015-encrypt-to-self t
|       mml2015-cache-passphrase t
|       mml2015-passphrase-cache-expiry 60
|       mml2015-verbose t)
`----

And in my gnus-posting-style something like

,----
| (setq gnus-posting-styles `((".*"
| 			    (name "Richard Riley")
| 			    (from "Richard Riley <riley-r-g@gmail.com>")
| 			    (eval(setq gnushush-user-agent-header (quote real)))
| 			    (signature-file "~/.emacs.d/.sigs/rgr.sig")
| 			    (eval (setq mml2015-signers '("b39d104a")))
| 			    (organization "aich tea tea pea dicky riley dot net"))))
`----

It's been a while since I went through to remove the wheat from the
chaff but the mml2025 (what!?) set are key for signing I think.

For caching the password my setup uses gpg-agent. The only messy thing I
found was the need to export the required environment variables in order
that things like emacs knew which cache process to talk to. For that I
used 

,----
| keychain && . $HOME/.keychain/$HOSTNAME-sh-gpg > /dev/null 2>&1 
`----

keychain takes care of using an existing agent or starting one if
necessary in .bash_env on my system. It might be unnecessary on a cleaner set
up. It caused quite a lot of frustration back when I got this
working. Hopefully enough to get you going,

I think you want to `M-x customize-group password'

Specifically, `password-cache' and `password-cache-expiry'

This is, I believe, what's used by smtpmail.el if it can't get the
password from auth-source.  I encourage you to use auth-source instead,
though.  You'd be storing the password in a PGP-encrypted file and you
can use the same file for IMAP, POP3, NNTP, etc. passwords.

Re: Password sending mail only once

[Richard Riley]

The basics of the password caching are bits with "cache" in them below -
as with all systems (well, Linux ones..) the devil is in the details of
how they deal with things like gpg-agent. Unfortunately Linux distros
tend to do things differently but the "same" kind of ... I battled like
hell with gpg-agent because of the way apps pick up how to talk to
it. 

Bottom line : you need a caching agent. Google up "password cache
agent" with your distro name and throw in emacs too and ...

The mml2015 stuff really confused me a while back because documentation
was thin on the ground and I really didnt know whether to use epa or
whatever. It was kind of in a transition phase at the time.

I suspect if you post your emacs version someone out there will have a
set up for you.

I am trying the below

; To avoid password on sending begin
;; (require 'auth-source)
(require 'auth-source "/home/tk/Emacs/ngnus-0.10/lisp/auth-source")
;; ;(require 'epa-file "~/elisp/epa-file.el")
(require 'epa-file)
;; (epa-file-enable)
;; ;(setq gnus-verbose 10)
;; (setq epa-file-cache-passphrase-for-symmetric-encryption t) ; VERY important
;; ;(setq epa-file-cache-passphrase-for-symmetric-encryption-timeout 60)
;; (if (file-exists-p "~/.authinfo.gpg")
;;     (setq auth-sources '((:source "~/.authinfo.gpg" :host t :protocol t)))
;;     (setq auth-sources '((:source "~/.authinfo" :host t :protocol t))))
; To avoid password on sending end

However, I didn't have auth-sources in my path so I changed to the
above.  Now also I don't have epa-file.el and I can't find it.  Where
can I download it ?

Moreover, is the above at all right?  I have just paste it from
somewhere but I dont really know what it is doing.

TK> I am trying the below

TK> ; To avoid password on sending end

Try this (I just put something like this together recently for Richard
Riley in this group):

(require 'epa-file)
(require 'auth-source)
(require 'cl)
(epa-file-enable)
(setq auth-source-debug t ; use `message' to log messages
      epa-file-cache-passphrase-for-symmetric-encryption t
      auth-sources '((:source "~/.authinfo.gpg" :host t :protocol t)))
(auth-source-user-or-password "login" "yourserver.com" "smtp")

...but you need to have the ~/.authinfo.gpg file.  Do you?

If it's set up properly, the last line should give you the user name
you've specified in your authinfo file.  If you say "password" instead
of "login" you'll get the password.  See the auth-source Info manual
that comes with Emacs 23.1 and newer if you have trouble setting the
authinfo file up.

You should have it if you're running a recent Emacs.  23.1 should work.

TK> Moreover, is the above at all right?  I have just paste it from

It's always better to understand things, but I realize you just want it
to work.  Thanks for being patient.
