So i am speaking about the use of a .authinfo.gpg.

About reading mails/news in gnus:
When i call gnus , i do not need any authentification because at this
moment, my mails are already retrieved by fetchmail. gnus have only to
bring my mails from my incoming directory to his directory (Mail).
But gnus try to read .authinfo.gpg if it exist.

I am asked a first time for my gpg passphrase.

/home/thierry/.authi: 0% (0/721)
/home/thierry/.authi: 100% (721/721)

I am asked a second time for my gpg passphrase.

/home/thierry/.authi: 0% (0/721)
/home/thierry/.authi: 100% (721/721)

Now gnus start normally.

NOTE: actually i don't know why i, when i start again gnus i am prompt
again (two times) for my passphrase like if :

,----
| (setq epa-file-cache-passphrase-for-symmetric-encryption t)
`----

have no effect.

My .authinfo.gpg:

,----
| machine api.del.icio.us:443 port https login xxxxxx password xxxxxxx
| machine smtp.gmail.com port 587 login xxxxxx password xxxxxxxxx
`----

The smtp line replace the old settings in .gnus.el:

,----
| ;; (setq smtpmail-auth-credentials '(("smtp.gmail.com" 587 
| ;; "my_email_as_login" "My_password")))
`----

My authinfo config in .emacs:

,----
| (require 'auth-source)
| (require 'epa-file)
| (epa-file-enable)
| (setq epa-file-cache-passphrase-for-symmetric-encryption t) ; VERY important
| (setq auth-sources '((:source "~/.authinfo.gpg" :host t :protocol t)))
`----

I hope i was clear, feel free to ask me more infos.
Thank you.
