Restricting incoming mail to only one IP Address

Reply Quote

We are using Postini to filter our mail but find that we are still receiveing mail that is not going through Postini. Is there a way I can configure Exchagne 2007 to only accept mail from the Postini IP address?

Thanks.

Jim

Hi Jim,

We use another spam filtering provider but we are still using Exchange 2003. Assuming the two versions are similar, I added the IP addresses of the sending spam filter servers to our gateway's Default SMTP Virtual Server properties, Access tab, Connection control button and checked the "Only the list below" option. You should be able to get the IP info from Postini.

Cheers,

Lem
