Me neither, see the sub-thread[1] about this in April on emacs-devel.

POP is only for fetching mail, not for sending.

Emacs (or Gnus) doesn't know that your Gnus configuration allows to
send mail, so it can't set `mail-user-agent' to `gnus-user-agent'.

Gnus (`message.el') tried harder than `sendmail.el' to figure out if
sendmail exists.  See the function and the variable
`message-send-mail-function':

--8<---------------cut here---------------start------------->8---
(defun message-send-mail-function ()
  "Return suitable value for the variable `message-send-mail-function'."
  (cond ((and (require 'sendmail)
              (boundp 'sendmail-program)
              sendmail-program
              (executable-find sendmail-program))
         'message-send-mail-with-sendmail)
        ((and (locate-library "smtpmail")
              (require 'smtpmail)
              smtpmail-default-smtp-server)
         'message-smtpmail-send-it)
        ((locate-library "mailclient")
         'message-send-mail-with-mailclient)
        (t
         (lambda ()
           (error "Don't know how to send mail.  Please customize 
`message-send-mail-function'")))))

;; Useful to set in site-init.el
(defcustom message-send-mail-function (message-send-mail-function)
  "Function to call to send the current buffer as mail.
The headers should be delimited by a line whose contents match the
variable `mail-header-separator'.

Valid values include `message-send-mail-with-sendmail'
`message-send-mail-with-mh', `message-send-mail-with-qmail',
`message-smtpmail-send-it', `smtpmail-send-it',

default is system dependent and determined by the function
`message-send-mail-function'.

`sendmail.el' just uses `sendmail-send-it' without any check if
/usr/sbin/sendmail (et al) even exist:

--8<---------------cut here---------------start------------->8---
;; Useful to set in site-init.el

(defcustom send-mail-function
  (if (and window-system (memq system-type '(darwin windows-nt)))

    'sendmail-send-it)

Bye, Reiner.
