Re: restrict users to internal email only

Hi Thomas,

This can be done with Kolab's recipient access list, which I think is 
undocumented. You can find it in kolab-webadmin in a user's "Configuration".

The access list will allow or deny addresses ending with the rule. A 
deny rule starts with a "-". So I think you need to add to the user's 
Recipient Access List:

-
$mydomains

This denies all except for mails to internal domains.

Best,

Lennart
