+@section How do I disable mail delivery without unsubscribing?
+
+Sometimes you may want to temporarily stop receiving all mailing list
+messages. This "vacation mode" is simple to do:
+
+@enumerate
+@item
+Go to the @url{https://lists.ffmpeg.org/mailman/listinfo/ffmpeg-user/, ffmpeg-user mailing list info page}
+
+@item
+Enter your email address in the box at very bottom of the page and click the
+@emph{Unsubscribe or edit options} box.
+
+@item
+Enter your password and click the @emph{Log in} button.
+
+@item
+Look for the @emph{Mail delivery} option. Here you can disable/enable mail
+delivery. If you check @emph{Set globally} it will apply your choice to all
+other FFmpeg mailing lists you are subscribed to.
+@end enumerate
+
+Alternatively, from your subscribed address, send a message to @email{ffmpeg-user-request@@ffmpeg.org}
+with the subject @emph{set delivery off}. To re-enable mail delivery send a
+message to @email{ffmpeg-user-request@@ffmpeg.org} with the subject
+@emph{set delivery on}.
+
+@anchor{Why is the mailing list munging my address?}
+@section Why is the mailing list munging my address?
+
+This is due to subscribers that use an email service with a DMARC reject policy
+which adds difficulties to mailing list operators.
+
+The mailing list must re-write (munge) the @emph{From:} header for such users;
+otherwise their email service will reject and bounce the message resulting in
+automatic unsubscribing from the mailing list.
+
+When sending a message these users will see @emph{via <mailing list name>}
+added to their name and the @emph{From:} address munged to the address of
+the particular mailing list.
+
+If you want to avoid this then please use a different email service.
+
+Note that ffmpeg-devel does not apply any munging as it causes issues with
+patch authorship. As a result users with an email service with a DMARC reject
+policy may be automatically unsubscribed due to rejected and bounced messages.
