Login Issues in Cpanel Godaddy

[deemsys]

Hi I have multiple cPanel's on GoDaddy in same server . and I'm maintaining different email accounts for different cPanel , but I'm facing a issue like i was able to login a different domain email from a another domains cPanel.

For example let say my domain name is facebook.com and I was able to login twitter.com mail from Facebooks webmail login.
webmail.facebook.com allows me to login in [email protected]

and it was able to see , get and send mail's as well.

could any body guide me to set the configuration properly.

Hello there! Just so I understand the situation, you're saying you can go to domain.com:2096 and then login with [email protected] and that works normally? If so, that is working as intended. You're authenticating to the webmail service on the machine, which isn't related to the cPanel user or domain that you've entered into the address bar.

Your email account is still limited to your personal data so there is no security issue from this.

We frequently see this behavior as some users log in with theirdomain.com:2096 and some users choose to use the server's hostname to access webmail, but they both allow them to log in normally.
