I know this may sound like a silly question (and probably is)

The e-mail address that the site will use (the contact us page, contact form) is this the one stored in the Tools > Admin Settings ?

The only reason is, I tested the contact page form and completed and no e-mail came through to the e-mail listed.

And I tested the actual e-mail address by sending an email to it from another e-mail account

Any ideas ?

Thanks
