SMTP Virtual server - Connection Restrictions

[talismanuk]

Some time ago on this forum, there was a really good explanation of how to stop Open Relay thru a Ms Exchange 2K server. One of the recommendations was to set the Connections option in the access tab of the SMTP virtual server ,and put in access to only allow your internal IP addresses .

Can someone explain this or am I missing something here ... My Exchange 2K server is conected to a Cisco PIX which is then connected via a leased line to an ISP (i.e. connection is virtually permanent.) When I put in the restrictions so that only INTERNAL IP addresses access the virtual smtp server .... E-mails go OUT but none are received. When I take away the restrictions .... everything is fine .... But obviously ANYONE can get access ....

Am I missing something here ??????

PS many thanks to the great tekkies who keep this site buzzin Thanks in anticipation

You wan to use the SMTP Virtual Server Properties. Under the Access Tab, and under the Relay... button mark Only the list below. In the list below add your ip address subnet range.

Ah, the hated relay question! Try this link. It'll give step by step on how to configure it properly. In addition, you shouldn't have a SMTP connector!
