Virtualmin roundcube password Drivers not work with error

[chris31520]

Hello,

I use identifiers in the form username@domain
when I validate the password change I get the following error:

No user named "username-domain-with-dash.fr" was found in the server "domain-with-dash.fr"

The problem is that if I integrate a code of this type:

$username = escapeshellcmd(str_replace('-'.$domain, '@'.$domain, $username));

my error becomes:

No user named "username@domain@[email protected]" was found in the server "domain-with-username.fr"

I'm using the latest online version of the virtualmin drivers and Roundcube version: 1.4.11
could you try to help me?
I will be grateful to you !
