<h1 class="topictitle1">Why Was the Email Address Format Changed in the SOA Record?</h1>
<div id="body1484624343246"><p id="dns_faq_009__p3110562492847">When you add a record set, you can enter an email address to receive error information and problem reports of the domain name. However, based on RFC 2142, we strongly recommend that you use <strong id="dns_faq_009__b1777118503202">HOSTMASTER@</strong><em id="dns_faq_009__i14512549205">Domain name</em> as the email address.</p>
<p id="dns_faq_009__p4001883493814">Because the at sign (@) has a special meaning in the SOA record set, the system replaces it with a dot (.) and includes a backslash (\) before the dot in the label before the at sign, but emails are still sent to the email address you have specified. For more information, see RFC 1035.</p>
<p id="dns_faq_009__p60348772144337">For example, if you enter <strong id="dns_faq_009__b84235270614459">test.hostmaster@example.com</strong> when you create the zone, the email address displayed in the SOA record set is <strong id="dns_faq_009__b842352706144559">test\.hostmaster.example.com</strong>.</p>
