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 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.

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 specified 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 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 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.
