Mike,
>I tried the mailto thing. Not quite what I was looking for. For one, the email client window opens, where I was hoping it would just send the email. Any way to make that happen?
Nope, that's the whole intent of mailto: is to launch the default email client in response to clicking a mailto: link on a web page.
>I also tried the mapimail approach. Outlook express is prompting me "another program is attempting to send email". Is there anyway to suppress that programmatically?
That's anti-virus preventative thing. I do think you can do a search and find a way to turn that off.
BLAT might be a silent alternative or some stuff from West-Wind.
