If I have one recommendation it would be to make sure that you don't let them bulk/mass mail through your normal outbound SMTP IP. That way even if they get the relay they are using blacklisted it will have minimal if any effect on your regular relay. Be aware though that some RBLs block an entire subnet so you could get caught up that way.
Other than that the cheapest way would be to set up a Linux box with Postfix to handle the relaying. Zero cost for OS and mail software is a good thing if you're looking to keep costs down. I know you said windows only but it's hard to do windows and keep the $$$ down.

We currently have one Imail server to handle all incoming and outgoing requests. A client of our has expressed an interest in a mass e-mailing program. As the administrator of the mail server, I have concerns with overhead and lag for all of our users. That said, what would be the best thing to do with regards to sending out 40K emails per day but *not* affecting the receiving/sending of mail of our existing user base? Would I be able to purchase additional hardware and software to simply spool the mass e-mailings? If so, what would be the best software to use for this purpose? (Something fairly inexpensive would be great.) Would there need to be any specific DNS settings needed? Lastly, the is for a Windows operating system. Thanks in advance, Che.
