NAME

       lmtptest - interactive LMTP test program


SYNOPSIS

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


DESCRIPTION

       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 multi-
       ple SASL authentication mechanisms and handles encryption layers trans-
       parently.  This  utility  is  often used for testing the operation of a
       lmtp server. Also those developing LMTP clients find it useful.



OPTIONS

       -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 spec-
              ified the strongest authentication mechanism  supported  by  the
              server is chosen.

       -a userid
              Userid  to use for authentication; defaults to the current user.
              This is the userid whose password or credentials  will  be  pre-
              sented 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  authen-
              tication.   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 mecha-
              nism specifying 0 will force lmtptest 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.

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

       -v     Verbose. Print out more information than usual.
