To solve this problem, replace the full stop with a double dot: |

The additional headers should be separated with a CRLF (rn). 可选参数。指定附加的header，如：From、Cc以及Bcc；如要继续添加header，则应该用（rn）隔开 Note: When sending an email, it must contain a From header. This can be set with this parameter or in the php.ini file. |

Note: Keep in mind that just because the email was accepted for delivery, it does NOT mean the email is actually sent and received.
