+@end smallexample
+
+@subheading Description
+A @dfn{mailer} is a special logical entity GNU Mailutils uses for
+sending messages. Its internal representation is discussed in
+@ref{Mailer}. The @code{mailer} statement configures it.
+
+The mailer statement contains a single sub-statement:
+
+@deffn {Configuration} url @var{str}
+Set the mailer @acronym{URL}.
+@end deffn
+
+GNU Mailutils supports two types of mailer @acronym{URL}s, described
+in the table below. As usual, square brackets indicate optional parts:
+
+@table @asis
+@item smtp://@var{host}[:@var{port}]
+Use an SMTP server @var{host} to send messages. Optional @var{port}
+specifies port number or symbolic name (as defined in
+@file{/etc/services}). It defaults to 25. The @var{host} can be
+specified as either an IP address in dotted-quad notation or as a
+symbolic host name. In the latter case, DNS system will be used to
+resolve it.
+
+@item sendmail://@var{progname}
+Use sendmail-compatible program
+@var{progname}. @dfn{Sendmail-compatible} means that the program must
+support following command line options:
+
+@table @option
+@item -oi
+Do not treat @samp{.} as message terminator.
+
+@item -f @var{addr}
+Use @var{addr} as the sender address.
+
+@item -t
+Get recipient addresses from the message.
+@end table
+
+@item sendmail:
+This is a special form of the @samp{sendmail} mailer. It uses the
+@command{sendmail} binary from the @code{_PATH_SENDMAIL} macro in your
+@file{/usr/include/paths.h}. It is the default mailer.
+
+@item prog://@var{progname}?@var{query}
+A @dfn{prog} mailer. This is a generalization of @samp{sendmail}
+mailer that allows to use arbitrary external programs as mailers.
+
+The @var{progname} must be a full pathname of the binary file. When
+sending message, Mailutils will invoke this file with the arguments
+specified by @var{query} and will pipe the message to be sent to its
+standard input.
+
+The @var{query} part is a list of arguments, separated by @samp{&}
+signs. Arguments may contain the following macro-substitutions:
+
+@table @samp
+@item $@{sender@}
+Expands to the sender email address.
+
+@item $@{rcpt@}
+Expands to the recipient email addresses.
