does anyone have any experience with e-mail protection appliances?
Have a look at IronPort (http://www.ironport.com/).
Ideally this would be a standalone box, serving as an ISP's SMTP relay, with the following functions:
Ok.
-- Detect spam coming from the ISP's customers, and automatically throttle the bandwidth or block SMTP for a given IP address.
Ok.
-- Alert the administrators when the spam or viruses are originating from ISP's network
I think this is not possible with this appliance right now. But I am sure, that IronPort can (and will) implement this if requested.
-- Manage the incoming email, and throttle the bandwidth for external IP addresses that send too many SMTP requests
Ok.
-- Built-in antivirus would be a plus
Ok. (SOPHOS) (and others in upcoming releases)
-- management web interface with privilege levels
Yes. More granular privilege levels in next release (IIRC).
-- interesting would be to have per-user spam filtering settings for incoming email...
You can create different policies for different users. You can apply these policies to users using attributes stored in a LDAP (or you can have static mappings on the appliance itself of course).
