NAME

       mprobe - smtp-server aliveness probe

SYNOPSIS

       mprobe hostname

DESCRIPTION

       The  mprobe(8zm)  is  usable  to test, if the named host (no IP address
       allowed!) has a smtp-server, that responds properly.

EXIT CODES

       0      All is well, smtp-server responded just fine

       2      Can’t resolve target hostname

       3      mprobe(8zm) internal failure, can’t create  socket  (should  not
              happen!)

       4      failed to connect to the remote host

       5      mprobe(8zm)  internal  failure,  fdopen()  failed..  (should not
              happen!)

       17, 19 The remote smtp-server hung-up on us, most likely

       18     The remote smtp-server did respond something,  but  it  did  not
              begin with "220"

       20     Timeout (60 seconds) from start of processing.

       99     Missing mandatory host parameter.
