Hi all,
does anyone have any experience with e-mail protection appliances?
Ideally this would be a standalone box, serving as an ISP's SMTP relay, with the following functions:
-- Detect spam coming from the ISP's customers, and automatically throttle the bandwidth or block SMTP for a given IP address.
-- Alert the administrators when the spam or viruses are originating from ISP's network
-- Manage the incoming email, and throttle the bandwidth for external IP addresses that send too many SMTP requests
-- Built-in antivirus would be a plus
-- management web interface with privilege levels
-- interesting would be to have per-user spam filtering settings for incoming email...
Your advice in choosing or avoiding vendors and solutions is very welcome.
Also there should be service providers that outsource such activities. Would be great to know the names as well.
thanks in advance, stan
