Hi,

Did you try to send message also from live server?
Because my host provider also use PHP back-end. I have gmail as well.
I am able to send message from the server to my mailbox BUT the exactly same code does not works from localhost. If you are unable to try your code on live server, then you have to check your PHP.ini file:
Look these code:

[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP_server=smtp.gmail.com
; http://php.net/smtp-port
smtp_port=587
auth_username=<yourmail@gmail.com>
auth_password=<your password>

; For Win32 only.
; http://php.net/sendmail-from
sendmail_from = <yourmail@gmail.com>

If you find the correct settings please let me know. I also not able to send mail from localhost…

I am not able to receive the email that is
