Title: Using Hosted email Security Post by: MicroED on Friday 11 June 2010, 07:53:39 am I use a hosted email security as front end to SMTP
If I want to use the SMTP proxy. How do I set the SMTP prox to allow only these 216.99.131.0/24 , 216.104.4.0/24 , 150.70.149.0/27 IP ranges and block all others. I think I set the "whitelist clients" for 216.99.131.0/24 216.104.4.0/24 150.70.149.0/27 but what do I set in the "blacklist clients" to stop all the others. Or is the setting something else.

Edit: Doesnt seem to work with the buildin smtp proxy. Title: Re: Using Hosted email Security Post by: MicroED on Friday 11 June 2010, 10:14:41 am Thank I have been using a port forwarding rule on port 25 incomming but I wanted to see the mail in the GRAPH logs ....
I have set the blacklist to 0.0.0.0/0 and it seem to be working now for now through the proxy. The mail server is also only allowing these IP addresses. |
