Aller dans Organization Name et entrer le nom désiré.
We have tried to make the name SquirrelMail as transparent as
possible. If you set up an organization name, most places where
SquirrelMail would take credit will be credited to your organization.
If your Organization Name includes a '$', please precede it with a \.
Other '$' will be considered the beginning of a variable that
must be defined before the $org_name is printed.
$version, for example, is included by default, and will print the
string representing the current SquirrelMail version.
[SquirrelMail]: Stan
