Moved over from StackOverflow. Sorry if you saw it there first

In an effort to keep us from being labeled spammers by major ISPs (in addition to SPF records, privacy policies, CANSPAM compliance and the like) - I wanted to limit the amount of mail we send out an hour. Is this possible in W2K3 SMTP server? I was looking at outbound connection properties in the SMTP virtual server config screens...It's just not that clear if tinkering with those settings are going to do what I want.

In a nutshell, I'd love mail being sent by this server to queue up and send for example, 5,000 messages every 10 minutes or so.

Mail is being sent via ASP.Net. Also, I wouldn't be sending 1 million a day. Probably 30,000 tops - and doing that only a few times a month. I'm just trying to avoid a tidal wave of 30k going out in 1 minute and setting off every network spam monitoring alarm in North America. I know I could do it with a combination console app / scheduled job. My question was if there was an easier way to accomplish this with the Virtual SMTP Server settings on Win2k3

Is this possible?
