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.


-t keyfile
 Enable TLS. keyfile contains the TLS public and private keys. Specify "" to negotiate a TLS encryption layer but not use TLS authentication.
-p port Port to connect to. If left off this defaults to imap as defined in /etc/services.
-m 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.
-a 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.
-u 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).
-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.
-r realm
 Specify the realm to use. Certain authentication mechanisms (e.g. DIGEST-MD5) may require one to specify the realm.
-f file
 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.
-I file
 Echo the PID of the running process into file (This can be useful with -X).
-x file
 Open the named socket for the interactive portion
-X file
 Like -x, only close all file descriptors & daemonize the process.
-o option=value
 Set the SASL option to value.
-v Verbose. Print out more information than usual.
-z Timing test.
