I had this working on my 6.01 but seem to be missing how to configure this on 7pre4 (or pre1, 2 or 3).
Setup: 7pre4 is set up to receive all email for the domain and then forward to an Exchange Server. The SME role is to reject unknow users, RBL, virus check and Spamassassin rate and then pass along to the Exchange server for delivery.
7pre4 performs extremely well, and even deletes Spamassassin rated mail above a set rating (6.01 was not able to do this). I have, however, not been successful in having it delete email to unknown users. It accepts and passes along all mail addressed to the domain, to the Exchange server.
I have one user account and a series of Pseudonyms set up, but that does not appear to cause the SME box to reject unknown users.
I have reviewed the settings and nothing jumps out at me.
Any suggestions?? Have I missed the obvious??
