+ <b>all</b> <b>(default)</b>
+ Replies to all addresses.
+
+ <b>sender</b> Replies only to the sender. If replying to user's own
+ message (Reply-to: or From: header is one of the user's
+ configured email addresses), try To:, Cc:, and Bcc: head‐
+ ers in this order, and copy values from the first that
+ contains something other than only the user's addresses.
+
+ <b>--decrypt=(false|auto|true)</b>
+ If <b>true</b>, decrypt any MIME encrypted parts found in the selected
+ content (i.e., "multipart/encrypted" parts). Status of the de‐
+ cryption will be reported (currently only supported with <b>--for-</b>
+ <b>mat=json</b> and <b>--format=sexp</b>), and on successful decryption the
+ multipart/encrypted part will be replaced by the decrypted con‐
+ tent.
+
+ If <b>auto</b>, and a session key is already known for the message,
+ then it will be decrypted, but notmuch will not try to access
+ the user's secret keys.
+
+ Use <b>false</b> to avoid even automatic decryption.
+
+ Non-automatic decryption expects a functioning <b>gpg-agent</b>(1) to
+ provide any needed credentials. Without one, the decryption will
+ likely fail.
+
+ Default: <b>auto</b>
+
+ See <a href='../notmuch-search-terms-7/'>notmuch-search-terms</a>(7) for details of the supported syntax for
+ <search-terms>.
+
+ Note: It is most common to use <b>notmuch</b> <b>reply</b> with a search string
+ matching a single message, (such as id:<message-id>), but it can be
+ useful to reply to several messages at once. For example, when a series
+ of patches are sent in a single thread, replying to the entire thread
+ allows for the reply to comment on issues found in multiple patches.
+ The default format supports replying to multiple messages at once, but
+ the JSON and S-Expression formats do not.
