Enabling a specific mail client for a particular domain

Issue :

When an user logs into webmail , he should just have one email client ( say roundcube ) whereas all other users should see all the three.

Solution :

Suppose the username is ‘xyzco’ for the domain xyz.com.

1. SSH into the server as root, and edit the file /var/cpanel/users/xyzco

2. Now, if you want to disable all webmail applications and enable roundcube mail, you would need to add following lines:

skiphorde=1
skipsqmail=1
skiprcmail=0

You can specify the values as per your requirement.

3. Then run the following command :

/scripts/updateuserdomains

4. And restart cPanel :

/etc/init.d/cpanel restart

Now, when the user xyzco logs into webmail, he will only see roundcube mail, and not the other two
