imtest is a utility that allows you to authenticate to a IMAP or IMSP
server and interactively issue commands to it. Once authenticated you
may issue any IMAP or IMSP 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 a imsp or imap server. Also those developing IMAP
clients find it useful.
Enable TLS. keyfile contains the TLS public and private keys.
Specify "" to negotiate a TLS encryption layer but not use TLS
Port to connect to. If left off this defaults to imap as defined
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.
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.
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).
-k num Minimum protection layer required.
-l 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.
Specify the realm to use. Certain authentication mechanisms
(e.g. DIGEST-MD5) may require one to specify the realm.
Pipe file into connection after authentication.
-n 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.
-s Enable IMAP over SSL (imaps).
-c Enable challenge prompt callbacks. This will cause the OTP
mechanism to ask for the the one-time password instead of the
secret pass-phrase (library generates the correct response).
-i Don't send an initial client response for SASL mechanisms, even
if the protocol supports it.
Echo the PID of the running process into file (This can be
useful with -X).
Open the named socket for the interactive portion
Like -x, only close all file descriptors & daemonize the
Set the SASL option to value.
-v Verbose. Print out more information than usual.
-z Timing test.
