+# We can use different programs to display various kinds of email attachments.
+# These programs will have the mail piped into them and are expected to output
+# it ready to display on a terminal (you can include terminal control
+# characters if you like, for colors and such). Emails will be stripped of
+# non-printable characters before being piped into these commands, and will be
+# encoded with UTF-8. These commands are invoked with sh and run
+# non-interactively, and their output is piped into your pager command
+# (interactively). The following environment variables will be set:
+#
+# $WIDTH: the width of the terminal window
+# $HEIGHT: the height of the terminal window
+# $MIMETYPE: the email's mimetype
+#
+# You can use * as a wildcard for any subtype of a given mimetype. When
+# displaying a text/* message and no command matches, the message will just be
+# piped directly into your pager (after being stripped of non-printable
+# characters).
+
+# Examples:
+#
+#text/html=w3m -T text/html -cols $WIDTH -dump -o display_image=false -o display_link_number=true
+text/*=fold -sw $WIDTH
+
+#
+# Default: less -r
+pager=less -r
+
+#
+# If an email offers several versions (multipart), you can configure which
+# mimetype to prefer. For example, this can be used to prefer plaintext over
+# html emails.
+#
+# Default: text/plain,text/html
+alternatives=text/plain,text/html
