Customer Sign-up Email error

[Lokee116]

Hello Im setting up my store and I was testing the customer sign-up and after submitting the information I get this error..

 

Warning: mail(): SMTP server response: 555 syntax error (#5.5.4) in D:\hshome\******\******\catalog\includes\classes\email.php on line 522

 

Warning: Cannot modify header information - headers already sent by (output started at D:\hshome\******\******\catalog\includes\classes\email.php:522) in D:\hshome\******\******\catalog\includes\functions\general.php on line 33

 

 

It still creates the customer but the customer doesnt recieve the welcome e-mail and they get that error page.

 

any tips to fix this?

 

some code:

 

line 522 of email.php

		return mail($to, $subject, $this->output, 'From: '.$from.$this->lf.implode($this->lf, $this->headers).$this->lf.implode($this->lf, $xtra_headers));

 

pls help or let me know if theres any other info you need to trouble shoot this.

 

Thanks!
