Error for New User login

[Shahrukh]

I have been recently trying to test my site by login users etc and I have been coming up with this error:

 

When a client logs in as a new user

When a client completes the confirmation order at checkout

When a client tries to get a password forgotten

 

I think it has to do with the smtp trying to send emails??????

Please help me out here.

 

I get the following errors:

Warning: mail(): SMTP server response: 501 5.5.4 Invalid Address in F:\hshome\bollywoo\milleniumdvd.com\catalog\includes\classes\email.php on line 502

 

Warning: Cannot modify header information - headers already sent by (output started at F:\hshome\bollywoo\milleniumdvd.com\catalog\includes\classes\email.php:502) in F:\hshome\bollywoo\milleniumdvd.com\catalog\includes\functions\general.php on line 29

 

I have checked my files and maybe am missing something. If you wish I can also send you my code for the email.php or config.php files etc

Please someone help me out here.

Thank you
