why doesnt opencart send contact email to gmail?

hi

why doesnt opencart send contact email to gmail?

thanks

It works just fine for my gmail.
Be sure your mail tab uses "MAIL" instead of "SMTP"

i have it set to "mail", but still it doesn't send email to gmail ie. info@gmail.com, but it does work for google apps gmail, ie. info@mydomain.com.

why is this?
