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.
