everything works until i try to send it i get this error messahe:
Warning: mail() [function.mail]: SMTP server response: 501 5.5.2 Syntax: RCPT TO: <address> in ...
what is wrong here and how to fix it?
and maybe a more broad question: if i get an error message that i cannot figure out where can i check for it? i tryed in google but did not get anything i could understand.
