Description
===========

**imtest** is a utility that allows you to authenticate to an IMAP server
and interactively issue commands to it. Once authenticated you may issue
any IMAP command by simply typing it in. It is capable of multiple SASL
authentication mechanisms and handles encryption layers transparently.
This utility is often used for testing the operation of an IMAP server.
Also those developing IMAP clients find it useful.

Options
=======

.. program:: imtest

.. option:: -t keyfile, --keyfile=keyfile

    Enable TLS.  *keyfile* contains the TLS public and private keys.
    Specify **""** to negotiate a TLS encryption layer but not use TLS
    authentication.

.. option:: -p port, --port=port

    Port to connect to. If left off this defaults to **imap** as defined
    in ``/etc/services``.

.. option:: -m mechanism, --mechanism=mechanism

    Force **imtest** to use *mechanism* for authentication. If not
    specified the strongest authentication mechanism supported by the
    server is chosen.  Specify *login* to use the LOGIN command instead
    of AUTHENTICATE.

.. option:: -a userid, --authname=userid

    Userid to use for authentication; defaults to the current user.
    This is the userid whose password or credentials will be presented to
    the server for verification.

.. option:: -u userid, --username=userid

    Userid to use for authorization; defaults to the current user.
    This is the userid whose identity will be assumed after
    authentication.

    .. Note::
        This is only used with SASL mechanisms that allow proxying
        (e.g. PLAIN, DIGEST-MD5).

.. option:: -k num, --minssf=num

    Minimum protection layer required.

.. option:: -l num, --maxssf=num

    Maximum protection layer to use (**0**\ =none; **1**\ =integrity;
    etc).  For example if you are using the KERBEROS_V4 authentication
    mechanism specifying **0** will force imtest to not use any layer
    and specifying **1** will force it to use the integrity layer.  By
    default the maximum supported protection layer will be used.

.. option:: -r realm, --realm=realm

    Specify the *realm* to use. Certain authentication mechanisms
    (e.g. DIGEST-MD5) may require one to specify the realm.

.. option:: -f file, --input-filename=file

    Pipe *file* into connection after authentication.

.. option:: -n num, --reauth-attempts=num

    Number of authentication attempts; default = 1.  The client will
    attempt to do SSL/TLS session reuse and/or fast reauth
    (e.g. DIGEST-MD5), if possible.

.. option:: -s, --require-tls

    Enable SSL over chosen protocol.

.. option:: -q, --require-compression

    Enable IMAP COMPRESSion (after authentication).

.. option:: -c, --do-challenge

    Enable challenge prompt callbacks.  This will cause the OTP mechanism
    to ask for the one-time password instead of the secret pass-phrase
    (library generates the correct response).

.. option:: -i, --no-initial-response

    Don't send an initial client response for SASL mechanisms, even if
    the protocol supports it.

.. option:: -I file, --pidfile=file

    Echo the PID of the running process into *file* (This can be useful
    with -X).

.. option:: -v, --verbose

    Verbose. Print out more information than usual.

.. option:: -z, --run-stress-test

    Timing test.

.. option:: -x file, --output-socket=file

    Open the named socket for the interactive portion.

.. option:: -X file

    Like -x, only close all file descriptors & daemonize the process.

.. option:: -w password, --password=password

    Password to use (if not supplied, we will prompt).

.. option:: -o option=value, --sasl-option=option=value

    Set the SASL *option* to *value*.
