The propagation of DNS is a progressive and non-linear phenomenon, as such, + very difficult to predict and to monitor.

There are online tools that allow us – in broad terms – to do so, comparing the data reported on some DNS servers around the world and comparing them with those of the “root server”, or DNS authoritative servers.

The main tools that can be used for this purpose are:

  • viewdns.info/propagation/
  • host-tracker.com
  • intodns.com

Not all DNS servers update as they should!

Unfortunately, individual DNS servers are left to the discretion of their provider.

It, therefore, happens that, in some cases, they are poorly configured, and therefore do not update with the due frequency.

For example, some providers update some of their DNS servers only once a week; so users who use those DNS servers of this provider “will discover” the new configuration only after a few days … (up to seven, depending on whether you were lucky enough to do so on the eve of the update or the day after …)

How to set email web client with your domain name.

CNAME Records

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)
etc
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

MX cpanel setup

MX cpanel setup

Save!!!
That’s all
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.
