NAME
       dnsmx - prints the MX records of fqdn
SYNOPSIS
       dnsmx fqdn
DESCRIPTION
       dnsmx  prints  the MX records of fqdn.  If there are no MX records, dnsmx prints an artificial MX record,
       simulating the behavior of MTAs.
       Normally dnsmx exits 0.  If dnsmx encounters a temporary problem that prevents it  from  determining  the
       list of MX records, it prints an error message and exits 111.
