Message Relaying in Exchange Server 5.5
LockedI have a server running Win 2000 Svr SP2 – Exchange Svr 5.5 SP4 – Proxy Server 2.0.
I have recently noticed an increase in the number of messages that are being relayed by my server that are not from or to any of the users on the domain.
I was wondering if there was any way to configure the IMS to reject relaying messages that are not from or to any of the users on the domain. The settings in the relaying tab in the administrator do not work for me because most of the users are dial up from outside the organization and when authentication required was selected any mail from external servers was rejected.
What I am looking for is a way to allow delivery from any external domain to users in my domain and reject any relaying through my domain from external servers to users external to our domain.
