# `--sasl-authzid`

Use this authorization identity (**authzid**), during SASL PLAIN
authentication, in addition to the authentication identity (**authcid**) as
specified by --user.

If the option is not specified, the server derives the **authzid** from the
**authcid**, but if specified, and depending on the server implementation, it
may be used to access another user's inbox, that the user has been granted
access to, or a shared mailbox for example.
