I have a Contact form on my site. I am using a free hosting site until I get this web site completed at which time I'll move it to a new paid host. In the meantime, I'm just trying to get things working.

I publish the site to the free host and go to my Contacts page and fill in the details and submit. After a short wait, I get this error:

[Error 201] Could not send email to 'stevec5375@gmail.com' from 'stevec5375@gmail.com' using the SMTP server 'smtp.gmail.com:587'. Please check if you have access to the SMTP server.

Since I'm using a free hosting site, I do not have an email account with them so I'm using Google's SMTP server. I know my account credentials and port are correct. No matter what I do, I can't get an email to send.

Does anyone have a clue as to what I'm doing wrong?

Here's a link to the page I'm working with:
