Error when sending e-mail notification
I get the following error message after submitting a bid. The user database is linked to phpbb2, the user has a valid e-mail address and the administrator e-mail is set.
Warning: mail() [function.mail]: SMTP server response: 503 5.5.2 Need Rcpt command. in C:\wamp\www\aof\cf\bids.php on line 220
Despite it only being an e-mail, no message is being sent.
Any help is appreciated.
