If the results of the DNS queries state that MDaemon<\/span><span style=\"font-family: \'Times New Roman\',Times,Georgia,serif; color: #010100;\">\'<\/span><span class=\"f_BodyText\">s IP address is a valid MX host for <\/span><span style=\"font-family: \'Courier New\',Courier,monospace; color: #010100;\">example.com<\/span><span class=\"f_BodyText\"> then MDaemon will automatically create a new Domain Gateway for it and accept its email. Messages for <\/span><span style=\"font-family: \'Courier New\',Courier,monospace; color: #010100;\">example.com<\/span><span class=\"f_BodyText\"> will then be stored in a special folder and, if you so choose, spooled to higher level MX hosts at each remote mail processing interval. This feature effectively enables you to become a backup server for another domain by simply configuring the DNS system to use your IP as an alternate MX host.<\/span><\/p>\n\r<p class=\"p_BodyText\"><span class=\"f_BodyText\">To help secure this feature, MDaemon can be configured to send a confirmation request to an email address of your choice. While MDaemon is waiting for the confirmation response, messages for the domain will be accepted and stored but not delivered. Confirmation requests must be replied to within an amount of time that you designate or the automatically created gateway will be removed and all stored messages deleted. If confirmation is received before the time has expired then the stored messages will be delivered normally.<\/span><\/p>\n\r<div style=\"text-align: left; text-indent: 0; padding: 0 0 0 0; margin: 0 3.0625rem 0.8750rem 3.0000rem;\"><table style=\"background-color:#ffffe6; border:solid thin #000000; border-spacing:0;\">\n\r<tr>\n\r<td style=\"vertical-align:top; width:3.1250rem; height:3.1250rem; padding:0.3125rem; border:none\"><p class=\"p_NoFormat\"><img style=\"margin:0;width:3.1250rem;height:3.1250rem;border:none\" src=\".\/images\/forbidden_50_yback.gif\"\/><\/p>\n\r<\/td>\n\r<td style=\"vertical-align:top; padding:0.3125rem; border:none\"><p class=\"p_Notes\"><span class=\"f_Notes\">It might be possible for a malicious person or &quot;spammer&quot; to attempt to exploit this feature by configuring their DNS server to list your MDaemon<\/span><span style=\"font-family: \'Times New Roman\',Times,Georgia,serif;\">\'<\/span><span class=\"f_Notes\">s IP address as one of their MX hosts.
