Hello All
getting following error how to solve this

Warning: mail(): SMTP server response: 503 RCPT first (#5.5.1) in

Thanks in advance

    According to the SMTP specification a 503 error means a "bad sequence of commands", for example

    If a RCPT command appears without a previous MAIL command, the server MUST return a 503 "Bad sequence of commands" response.
