Important: You must send the email from the same e-mail address you use for your CoffeeCup account (the one you log in to S-Drive with). The subject line of the e-mail will be the header of the post, and of course, the body text will be the body text of the post.

Because that is how it works Mike.

On your cell phone, you configure your e-mail client so that you can post to your Stream from that phone.

with thousands of people sending mail to post@coffeecup.com they use the from email info to decide what stream to put that email into.

I would have to agree, I found the page vague with little to no technical info.

What exact technical information do you require? We have found that if we put too much information on the page, it becomes too technical and people get more confused. If we add too little, then we have questions such as this. Our goal is to make it "just right".
