+The @code{(gnu home services mail)} module provides services that help
+you set up the tools to work with emails in your home environment.
+ 
+@cindex msmtp
+@uref{https://marlam.de/msmtp, MSMTP} is a @acronym{SMTP, Simple Mail
+Transfer Protocol} client.  It sends mail to a predefined SMTP server
+that takes care of proper delivery.
+ 
+The service reference is given below.
+ 
+@defvar home-msmtp-service-type
+This is the service type for @command{msmtp}.  Its value must be a
+@code{home-msmtp-configuration}, as shown below.  It provides the
+@file{~/.config/msmtp/config} file.
+ 
+As an example, here is how you would configure @code{msmtp} for a single
+account:
+ 
+@lisp
+(service home-msmtp-service-type
+         (home-msmtp-configuration
+          (accounts
+           (list
