Gmail now requires senders to authenticates with spf and dkim signing. When mail is sent via php send mail, dkim signing does not take effect, and so maiul is being rejected. You will need to manually go in and set the headers to be placed on emails being sent this way or you can try using the phpmailer function (first link) to send mail.
