:code:`compose-mail`. To use ``notmuch`` for this, customize this
variable to the symbol :code:`notmuch-user-agent`.
+:index:`message-dont-reply-to-names`
+
+ When composing mail replies, Emacs's message mode uses the
+ variable :code:`message-dont-reply-to-names` to exclude
+ recipients matching a given collection of regular expressions
+ or satisfying an arbitrary predicate. Notmuch's MUA inherits
+ this standard mechanism and will honour your customization of
+ this variable.
