Bug? Add forwarder dialog accepting Uppercase Emailadress (green checkmark)

When adding forwarders via the Cpanel Webmail screen (Port 2096) the emailadress can be entered with uppercase characters and a green checkmark is displayed.

When trying to submit the form the creation of the forwarder the following error message is displayed:

Code:

-- Add a New Forwarder

All email that is sent to “” will forward to “”
(Warning: “Uppercase@Domain.TLD” does not refer to a valid local email account or alias. The system will not create a forwarder, because it already sends that email to the default address.) 

When adding the email in lowercase the forwarder is created.

Perhaps the dialog can be changed to just convert uppercase to lowercase. The green mark is misleading. IMHO lowercase was always the way to go to prevent ugly things in the backend ;-)

Not sure what to put into the bugreport. Allow uppercase, just convert to lowercase or remove green checkmark when uppercase characters are in the field.

Thanks.

 

Thanks for your post.

The green check mark is only on x3 Themes. Paper Lantern shows nothing.
When using Paper Lantern the uppercase email is accepted and no error message is shown.
But the forwarder is not created. This is all done via the webmail account of a email user.

Installed Version: 11.48.3.0
Current Tier: stable

This behaviour was also reproducable under lower versions. I was asked by a user about this problem. I think most users are just used to enter emails in lower case.

 

In a nutshell. Emailadresses can be entered with uppercase characters. Error message in x3, no error in paper lantern. But it isn't possible to add these emailadress as forwarders. Everything has to be lowercase.
In x3 you get the error message as quotes in my first post, paper lantern presents an empty screen where you can click to go back.

I had some users which complained about that. Since they get warning as long as the email is not complete or correct I can understand that some user are irritated.
So please change the check routines during entering the emailadress to complain about uppercase characters.
Or just convert all entered characters to lowercase.

I am not looking for instructions how to add a forwarder. I am looking for a consistent behaviour of the GUI.
Thanks for your time and pushing me to check paper lantern again.
