AspEmail is a freeware solution that does this and only this while I think you can do alot more with wwIPStuff. So if you don't want the extra stuff, check out www.aspemail.com. However, it does add another ActiveX control you need to register on the client side. I'm not sure if wwIPStuff requires this.

>>I've had good luck with wwIPStuff. I believe you can still download it free, and it just requires that your mail server be SMTP compatible. You can tell it to use whatever you want for the sender info, and it doesn't leave any trace in your e-mail software. (i.e. it doesn't leave a message in the "Sent items" of OE.)
