Kolab 2.2-rc2: problem on Distribution Lists

[Alessio Cecchi]

After upgrade from 2.1.0 to 2.2-rc2 i have a problem with "Distribution 
Lists", if i insert and external e-mail address kolab gives me this error:

"Errors:
No user with email address, UID or alias alessio at pippo.com"

So i can't insert forward to external e-mail address but only alias on local 
server.

Is a know bug?
Thanks
