remote user fails in creating email account since version 2.2.23

Hi,

It seems remote user fails in creating email account since version 2.2.23.

Using 2.2.21, it ran ok creating emails accounts.

I upgrade to 2.2.23. The remote user still create successfuly sites but not emails accounts.

Here is the debug output:

Aditionaly I openned ISPconfig control panel to check email account creation. email is shown in "user&email" but none of the two checkbox "@www.mysite.com", "@mysite.com" is checked ...

Thanks for any help.
