NAME

       pop3test - Cyrus IMAP documentation

       Interactive POP3 test program.

       This is actually installed as a hard linked copy of imtest(1).

       It allows you to authenticate and send POP commands to the server.

SYNOPSIS

          imtest [ -t keyfile ] [ -p port ] [ -m mechanism ]
              [ -a userid ] [ -u userid ] [ -k num ] [ -l num ]
              [ -r realm ] [ -f file ] [ -n num ] [ -s ] [ -q ]
              [ -c ] [ -i ] [ -z ] [ -v ] [ -I file ] [ -x file ]
              [ -X file ] [ -w passwd ] [ -o option=value ] hostname

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

       -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.

       -p port, --port=port
              Port to connect to. If left off this defaults to imap as defined in /etc/services.

       -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.

       -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.

       -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).

       -k num, --minssf=num
              Minimum protection layer required.

       -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.

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

       -f file, --input-filename=file
              Pipe file into connection after authentication.

       -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.

       -s, --require-tls
              Enable SSL over chosen protocol.

       -q, --require-compression
              Enable IMAP COMPRESSion (after authentication).

       -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).

       -i, --no-initial-response
              Don't send an initial client response for SASL mechanisms, even if the protocol supports it.

       -I file, --pidfile=file
              Echo the PID of the running process into file (This can be useful with -X).

       -v, --verbose
              Verbose. Print out more information than usual.

       -z, --run-stress-test
              Timing test.

       -x file, --output-socket=file
              Open the named socket for the interactive portion.

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

       -w password, --password=password
              Password to use (if not supplied, we will prompt).

       -o option=value, --sasl-option=option=value
              Set the SASL option to value.
