+## sending mail using smtpmail
+
+<!-- By default message mode will use the system `sendmail` command to send
+mail. However, on a typical desktop machine there may not be local SMTP
+daemon running (nor it is configured to send mail outside of the system). -->
+
+If setting up local `sendmail` or `msmtp` is not feasible or desirable,
+the Emacs `smtpmail` package can be used to send email by talking to remote
+SMTP server via TCP connection. It is pretty easy to configure:
+
+1. Emacs variable `message-send-mail-function` has not been set
+
+   Initially, Emacs variable `message-send-mail-function` has value of
+   `sendmail-query-once`. When (notmuch) message mode is about to send email,
+   `sendmail-query-once` will ask how emacs should send email. Typing `smtp`
+   will configure `smtpmail` and Emacs may prompt for SMTP settings.
+
+1. `M-x customize-group RET smtpmail`
+
+   As a minimum, 'Smtpmail Smtp Server' needs to be set.
+
+   After doing that, continue with `M-x load-library RET message` and
+   `M-x customize-variable RET message-send-mail-function`.
+   In the customization buffer select `message-smtpmail-send-it`.
+
+1. Set some variables in .emacs or in [notmuch init file](/notmuch-emacs#notmuch_init_file)
+
+        (setq smtpmail-smtp-server "smtp.server.tld" ;; <-- edit this !!!
+        ;;    smtpmail-smtp-service 25 ;; 25 is default -- uncomment and edit if needed
+        ;;    smtpmail-stream-type 'starttls
+        ;;    smtpmail-debug-info t
+        ;;    smtpmail-debug-verb t
+              message-send-mail-function 'message-smtpmail-send-it)
+
+Note that emacs 24 or newer is required for `smtpmail-stream-type`
+(and smtp authentication) to be effective.
+
+More information for smtpmail is available:
+

 ## <span id="address_completion">Address completion when composing</span>
 
 There are currently three solutions to this:
 

+### notmuch address
+
+Starting with Notmuch 0.21, there is a builtin command to perform
+autocompletion directly within Notmuch. Starting with 0.22, it is
+configured by default, so if you have previously configured another
+completion mechanism, you may want to try out the new internal
+method. Use `M-x customize-variable RET notmuch-address-command` and
+reset the value to "internal address completion" (`'internal` in
+lisp).
+
+If you are not yet running 0.22, you can still use it by adding a
+wrapper around the command called, say, `notmuch-address`:
+
+    #!/bin/sh
+    exec notmuch address from:"$*"
+
+Then you can set the `notmuch-address-command` to `notmuch-address`
+(if it is in your `$PATH` of course, otherwise use an absolute path).
