You can change domains or add additional domains to individual users mailboxes but there's nothing that will stop anyone who wanted to from forging mail as coming from your domain if they like. This is the nature of SMTP.

Because they are all different I believe that some bulk email company is handling the mail for these companies.

This is getting to the point of being ridiculous. Any spammer, it would seem, can take any legitimate address and begin an email campaign and let that domain worry about any of the bounces as well as disgruntled users receiving the email and thinking it was from us. If we decide to change our email domain to something else can both old and new email addresses be resolved to a single individual/mailbox for some period of time then drop the one being used by bulk mailers. I am also in the midst of upgrading to AD in order to move to E2k so am unclear of all the impact this may have. Also is there anything that can be done to try to mitigate this issue in the future.
