Controlling Quantity of Attachments Leaving Domain

[RedRum]

What if you want to monitor/control the quantity of outgoing attachments from your domain through exchange? For instance, you don't want all of your companies confidential/proprietary forms etc... emailed home/offsite by defecting employees. We don't want to stop all outgoing attachments, just bulk exodus. Also, it would be nice to log outgoing attachment activity to see if there is a slow bleed going on.

1) Is there a way to do this from the exchange server?

2) What if the user switches to a different outgoing SMTP server in the email client? Is there a way to control this as it leaves the network some other way?

I'm not too sure you can do what you're wanting with Exchange. I use a program called Mailwall. I can limit attachments by type or size. I also can limit a certain size to be sent at off-peak hours. You can hold msgs per user if you want, or remove them altogether. [sig][/sig]

1.) You can set limit of message size with Exchange. That is as far as you can go with Exchange. Check out Mail Essentials it sounds like it could do what you want.

2.) With a firewall you could block the ports that would allow a user to connect to an external POP3 server.

If you turn on tracking you can use Crystal Reports to compile reports of the traffic.
