Bug#1148867: Button "Add Mail settings" throws a Fatal error: Uncaught Error: Undefined constant "active" in /usr/share/gosa/plugins/personal/mailaddress/class_mailAccount.inc:198

[Serhii Horichenko]

Package: src:gosa
Version: 2.8~git20230203.10abe45+dfsg-19
Severity: important

(GOsa² 2.8~git20230203.10abe45+dfsg-1+deb12u2 on `Debian Edu 12.15`  
has the same issue.)

Environment:
- Server Debian Edu 13.7 server with only the role "Main-server"
- (optional) Workstation installed with PXE from server above

How to reproduce:
- GUI log in to the system as any user
- Open Firefox with the default page `https://www/index.html.en`
- Choose GOsa² on the right-side menu
- Log in to GOsa²
- Open any user's account in GOsa²
- Choose the tab Mail (https://www/gosa/main.php?plug=1)
- Press the button "Add Mail settings"

Instead of a webpage, you can observe the ERROR:
```
