[snip] PHP Warning: mail() [function.mail<http://develop1/credit%20card%20processing/Submit/ChildSu pport/function.mail>]: SMTP server response: 504 <br />: Recipient address rejected: need fully-qualified address. The value of $user_email when it is echoed out above is user@xxxxxxxxxxx [/snip] Just a sanity check, does the e-mail address have that period at the end of it when you echo it out? That would make the address non fully qualified because the server is expecting a top level domain to follow. Just for giggles check the FROM address as well, it needs a fully qualified domain too. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
