- ``--folder=<``\ folder\ **>**
- Deliver the message to the specified folder, relative to the
- top-level directory given by the value of **database.path**. The
- default is to deliver to the top-level directory.
+.. program:: insert
+
+.. option:: --folder=<folder>
+
+ Deliver the message to the specified folder, relative to the
+ top-level directory given by the value of **database.path**. The
+ default is the empty string, which means delivering to the
+ top-level directory.
+
+.. option:: --create-folder
+
+ Try to create the folder named by the ``--folder`` option, if it
+ does not exist. Otherwise the folder must already exist for mail
+ delivery to succeed.
+
+.. option:: --keep
+
+ Keep the message file if indexing fails, and keep the message
+ indexed if applying tags or maildir flag synchronization
+ fails. Ignore these errors and return exit status 0 to indicate
+ successful mail delivery.
+
+.. option:: --no-hooks
+
+ Prevent hooks from being run.
+
+.. option:: --world-readable
+
+ When writing mail to the mailbox, allow it to be read by users
+ other than the current user. Note that this does not override
+ umask. By default, delivered mail is only readable by the current
+ user.
+
+.. option:: --decrypt=(true|nostash|auto|false)
+
+ If ``true`` and the message is encrypted, try to decrypt the
+ message while indexing, stashing any session keys discovered. If
+ ``auto``, and notmuch already knows about a session key for the
+ message, it will try decrypting using that session key but will
+ not try to access the user's secret keys. If decryption is
+ successful, index the cleartext itself. Either way, the message
+ is always stored to disk in its original form (ciphertext).
