smtpmail-async 1.0

[John Wiegley]

* What is it

Using the new async.el, it's now possible to send SMTP mails with Emacs in the
background in just 12 lines of code:

    (defun async-smtpmail-send-it ()
      (async-start
       `(lambda ()
          (require 'smtpmail)
          (with-temp-buffer
            (insert ,(buffer-substring-no-properties (point-min) (point-max)))
            ;; Pass in the variable environment for smtpmail
            (async-inject-environment "\\`\\(smtpmail\\|\\(user-\\)?mail\\)-")
            (smtpmail-send-it)))
       'ignore))

Now you can send e-mail without waiting, and without relying on system
services like sendmail.
