E-Mail "Contact Us" HELP!!

[launchpad]

I know it can't be this hard, but I can not get the "Contact Us" link to work in the forum. I went into the options area in the administration page and clicked on "E-Mail Options" and set the lower area of that page to my SMTP (which is Google) and get a failure page when I try to send a message. Any ideas as to why this is happening or what I can do to fix this? Thank you in advance....
