REVLY DNS Guide
The REVLY Communication Server does not provide DNS services. You may install BIND on the server, or better, use another DNS provider such as your registrar or ISP.
Mail Exchange (MX) Records
Mail exchange records tell email servers where to send email for your domain. With REVLY you must set a primary mail exchanger. To start receiving emails at REVLY you will need to remove any existing MX records associated with your domain. Then add the following records to your name server.
example.com. MX mail.example.com.
Address (A) Records
Address records point domain names to ip addresses. An Address record pointing to your server is required. Create an entry in your DNS zone file similar to this one:
mail.example.com. A <ip-address-of-server>
Canonical Name (CNAME) Records
Canonical name records tell web browsers and mail clients alternate names for servers on the Internet. REVLY uses CNAME records to direct browsers to webmail and administration panels. Additionally CNAME records are used to direct instant messages to REVLY. If any of these records exist for the names below, please remove them from your name server before proceeding.
im.example.com. CNAME mail.example.com. conference.example.com. CNAME mail.example.com.
Optional CNAME records can be added to facilitate default email client settings:
imap.example.com. CNAME mail.example.com. pop.example.com. CNAME mail.example.com. smtp.example.com. CNAME mail.example.com.
Service Locater (SRV) Records
Server locater records tell clients which servers to use for certain services on the Internet. REVLY uses SRV records to direct instant messaging servers and clients to REVLY's servers. If your name server does not support adding SRV records you may omit these steps, however, performance will be degraded.
_stun._tcp.example.com. SRV 5 25 3478 im.example.com. _stun._udp.example.com. SRV 5 25 3478 im.example.com. _stuns._tcp.example.com. SRV 5 25 5349 im.example.com. _xmpp-client._tcp.example.com. SRV 5 25 5222 im.example.com. _xmpp-server._tcp.example.com. SRV 5 25 5269 im.example.com.
Note: The entries above are in DNS zone file format. You may need to adjust the syntax according to your DNS management tools provided by your vendor.
