MDaemon will try each DNS server once per lookup operation and in sequence until it exhausts the complete list of DNS servers or finds the first one that works. If you include additional DNS servers in the <\/span><span class=\"f_ControlIndent\" style=\"font-style: italic;\">Manually configured DNS Servers<\/span><span class=\"f_ControlIndent\"> option below, MDaemon will try those servers as well. Finally, at startup the System log will display each DNS server and indicate its source (i.e. manually configured or taken from Windows).<\/span><\/p>\n\r<p class=\"p_ControlHeading\" style=\"page-break-after: avoid;\"><span class=\"f_ControlHeading\">Reload DNS server hourly<\/span><\/p>\n\r<p class=\"p_ControlIndent\"><span class=\"f_ControlIndent\">Check this box if you wish to reload the DNS server every hour.

If you enable the <\/span><span class=\"f_ControlIndent\" style=\"font-style: italic;\">Use Windows DNS servers<\/span><span class=\"f_ControlIndent\"> option above, MDaemon will also query all DNS servers found within your Windows TCP\/IP configuration.
