+The @code{(gnu home services mail)} module provides services that help

+
+@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.

+account:
+
+@lisp
