it’s useful for instance, to rename a webmail client in case of your email being managed by an external provider.
CNAME stand for canonical nome a “CNAME stands for Canonical Name. CNAME records can be used to alias one name to another.”
It’s like a nickname … your name is Elizabeth but someone calls you Betty and when you hear one of two you respond…but what is more is that Betty will appear as to be your native name.
HOW TO SET WEB CLIENT WITH YOUR DOMAIN NAME
If you own your domain and entrust your email service to an external provider, it ‘s really probably that you will read the email via the client proposed by your provider that will use it’s own domain.to
This it’s not always appreciated especially from who, owning its domain, feel stronger inside the need to show it’s brand and mark its visibility.
So here we are to show how it’s easily renaming external email provider email client (Roundcube, SquirrelMail, Rainloop etc) and let it appear as is was yours.
A CNAME record on your DNS setup, basically allows that a link like: emailclient.myprovider.com being turned into myemailclient.mydomain.ltd (or whatever you need).
In your DNS panel you’ll find several records :
MX (to point the email server provider)
A (to set web entry)
and you can also configure one, or more, CNAME records.
This example, you can find more details here, it’s based a servermx’ Roundcube client.
A servermx’ customer can access to its mail in several ways: one of this is the Roundcube client at roundcube.servemx.com.
If the customer domain, for instance, being mydomain.com he must to:
Go to DSN PANEL
ADD CNAME mywebclient.mydomain.com roundcube.servemx.com
Now mywebclient.mydomain.com will point the Roundcube client of the external email provider, but the link showed to the email user will be
emailclient.shopstars.com and your custom Webmail URL will be set up.
