       Interactive LMTP test program


       lmtptest [ -t keyfile ] [ -p port ] [ -m mechanism ]
           [ -a userid ] [ -u userid ] [ -k num ] [ -l num ]
           [ -r realm ] [ -f file ] [ -n num ] [ -c ] [ -i ]
           [ -v ] [ -w passwd ] [ -o option=value ] hostname


       This is actually installed as a hard link to imtest(1).

       lmtptest  is  a utility that allows you to authenticate to a LMTP server and interactively
       issue commands to it. Once authenticated you may issue any LMTP 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  lmtp
       server. Also those developing LMTP 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 lmtp as defined in /etc/services.

       -m mechanism
              Force lmtptest 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.

                 This is only  used  with  SASL  mechanisms  that  allow  proxying  (e.g.  PLAIN,

       -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.

       -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.

       -v     Verbose. Print out more information than usual.

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

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