This script can be abused. I can insert newlines into the usermail field and have the contents emailed to anyone I want.

If you've ever gotten SPAM that started out as something like "here is the contents of your feedback form", followed by some spam, it's from a script like this.

Please do not deploy this script. Your server will be blackballed within hours of the first SPAM sent using it. Then good luck getting back on the good side of the blacklisters.

Additionally, I think this is based on a common script which has this flaw (is it Matt Wright's "mailform", or something like that?), so the following is a lie:

It's not nice to lie within a community of contributors. {sigh}
