I am currently evaluating Scalix and I've come across a minor issue. I've set things up so my Scalix server is going to be the server for the domain "something.com". If someone sends an email to "info@something.com", which is not setup as a user and won't be; the email is not immediately rejected as "unknown user". Instead sendmail just loops it around to itself, because this server has been setup as MX for "something.com" until the maximum number of hops is reached.
Is there someway to setup things so if the user is unknown it immediately rejects the email?
Thanks.
