This is an example of how to set DNS records for a domain on the IceWarp Server. In this example, we are using the following values:
Domain: example.com
Domain mail server: mail.example.com
MX record
A mail exchanger record specifies the mail server responsible for accepting email messages on behalf of a domain name.
@ IN MX 5 mail.example.com
Webmail (WebClient)
Webmail records are important for WebClient itself and its function.
webmail.example.com IN CNAME mail.example.com
webclient.example.com IN CNAME mail.example.com
Autodiscover settings
Autodiscover is a mechanism that allows clients such as Outlook, IceWarp Desktop Client, Exchange Active Sync clients, as well as iOS (iPhone,iPad) and Android devices to easily configure their email knowing only their email address and password.
autodiscover.example.com IN CNAME mail.example.com
_sip._tcp.example.com IN SRV 1 5 5060 mail.example.com
_sip._udp.example.com IN SRV 1 5 5060 mail.example.com
_sip._tls.example.com IN SRV 1 5 5061 mail.example.com
_autodiscover._tcp.example.com IN SRV 1 5 443 mail.example.com
_caldav._tcp.example.com IN SRV 1 5 80 mail.example.com
_caldavs._tcp.example.com IN SRV 1 5 443 mail.example.com
_carddav._tcp.example.com IN SRV 1 5 80 mail.example.com
_carddavs._tcp.example.com IN SRV 1 5 443 mail.example.com
_ischedule._tcp.example.com IN SRV 1 5 80 mail.example.com
_ischedules._tcp.example.com IN SRV 1 5 443 mail.example.com
_xmpp-client._tcp.example.com IN SRV 1 5 5222 mail.example.com
_xmpp-server._tcp.example.com IN SRV 1 5 5222 mail.example.com
SPF settings
The Sender Policy Framework SPF can specify which IP addresses and/or hostnames are authorized to send email from the specific domain. This example record contains only an MX server. You can create your own record with wizard www.spfwizard.net.
example.com IN TXT "v=spf1 mx"
DKIM settings
DKIM creates a domain-level authentication framework for email using private-key technology and a DNS record to prove the source and content of a message.
You can find out more about DKIM settings in the article How To Setup DKIM For Your Domain or in our IceWarp Academy video.
Don't use the following record for your domain, it is just an example of how the DNS record looks.
selector._domainkey.example.com IN TXT "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDF7YO5k+lRQGgI4oSEbO71gkFK3Rwav1bA6F9uYJQPIXJZBxWc/b+SXmEgxXpNvFhACLufp2BF444d7qxRyIv+7RCsoWoefisnBZky5BslHMLgJ7Q8PedZdl1nyK2qQYMUSy8c8dYrLgYAcOWCoVRXCwQ5gKytgkgmlDB2lrxWNQIDAQAB"
