I have just taken over responsibility for an SBS2003 installation. I am just getting my head around the setup and identifying issues and have found the following configuration that I am not familiar with.
The Exchange server all appears to working ok but does not have any SMTP 'connector'. By default SBS2003 has a 'SmallBusiness SMTP connector' setup. However that does not exist.
Currently all inbound mail is directed through a 3rd party server which is doing virus/spam scanning and the Default SMTP Virtual Server has IP restrictions only allowing incoming connections from the 3rd part server.
It is my intention to install local security solutions and accept email directly into the server. However I am confused about the lack of SMTP connector. How do I specifiy Use DNS, How do I ensure that the server is not acting as an Open Relay.
Do I just create an SMTP connector?
Should I rerun the EICW, will this create the connector?
How is outbound email currently handled if there is no connector?
Thanks for any help you can provide.
