The AutoDiscovery service ensures that email accounts can be automatically configured in various email clients and devices.
Step 1: AutoDiscover via XML files
Some email clients need an XML file to obtain the email account settings. If you use our full service email, we host the XML for you and you can make it work by adding the below DNS records for your domain. You may also choose to host the XML file yourself http(s)://on autoconfig.yourdomain.com. An example can be found here.
autoconfig IN CNAME autoconfig.dynu.com. @ IN TXT "mailconf=https://autoconfig.dynu.com/mail/config-v1.1.xml"
Step 2: AutoDiscover via SRV records
RFC6186 specification describes how SRV records can be used to locate email services. The below SRV records need to be added for your domain. For dynu.biz, the yourdomain-extension-mail.dynu.com is dynu-biz-mail.dynu.com.
_autodiscover._tcp IN SRV 0 0 443 autodiscover.dynu.com. _imap._tcp IN SRV 10 0 143 yourdomain-extension-mail.dynu.com. _imaps._tcp IN SRV 0 0 993 yourdomain-extension-mail.dynu.com. _pop3._tcp IN SRV 20 0 110 yourdomain-extension-mail.dynu.com. _pop3s._tcp IN SRV 10 0 995 yourdomain-extension-mail.dynu.com. _smtp._tcp IN SRV 10 0 25 yourdomain-extension-smtp.dynu.com. _smtps._tcp IN SRV 0 0 465 yourdomain-extension-smtp.dynu.com. _submission._tcp IN SRV 0 0 587 yourdomain-extension-smtp.dynu.com.
NOTE: If you use our full service email and also host your domain's DNS with us, all records in Step 1 and Step 2 were added for you when you activated the full service email. If you need assistance with the DNS records, open a support ticket here.
