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

(require 'epa-file)
(require 'auth-source)
(require 'cl)
(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" "" "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.

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