Configuring DNS for instant messaging
About SRV records
SRV (service) records are entries in your DNSDomain Name System - Enables the translation of hostnames to IP addresses and provides other domain related information. which specify the location of service servers. You must configure SRV records to make instant messaging in Kerio Connect accessible from other servers.
There are two types of SRV records:
- xmpp-server — necessary if you enable sending messages outside of your domain
- xmpp-client
Go to the Kerio Connect administration (Configuration > Instant MessagingInstant messaging is a real-time online chat.) to check if the SRV records for your domain are configured. For more information refer to Configuring instant messaging in Kerio Connect.
You must add SRV records on your DNS server or use the management interface of your DNS registrar to add the records.
NOTE
Visit XMPP wiki for more information on SRV records.
