Pretty generic. Several smtp firewall proxies return just this.

Where is the DOCUMENTATION ? It is all over the place ... On
your own system, try "man" and "info" and "apropos", and also
look under the /usr/share/doc/<package> or /usr/doc/<package>.
Online, http://newbiedoc.sourceforge.net, and linuxdoc.org and
debianhelp.org
