Are you hosting on a Linux or other Unix-like systems? If so, depending on where the server(s) where the page is hosted, you need to ensure that sendmail or postfix is actually running.
As root you can run 'mailq' (see man pages) to see if the message is being queued up but there is no daemon running that is processing it.
Also double-check your spam folder to see if it is getting tagged as such by gmail.
