Email Header Sending Problem

[jello18]

Dear All,

 

I have just installed the OSC and tried to test the customer function, after I confirmed the order, I recieved the below error :

 

Warning: mail(): SMTP server response: 451 See http://pobox.com/~djb/docs/smtplf.html. in C:\Inetpub\vhosts\katachi-do.com\httpdocs\includes\classes\email.php on line 510

 

Warning: Cannot modify header information - headers already sent by (output started at C:\Inetpub\vhosts\katachi-do.com\httpdocs\includes\classes\email.php:501) in C:\Inetpub\vhosts\katachi-do.com\httpdocs\includes\functions\general.php on line 29

 

I haven't changed anything , but in the admin setting , I used the below setting:

 

E-Mail Options

 

E-Mail Transport Method - smtp

E-Mail Linefeeds - CRLF

Use MIME HTML When Sending Emails - false

Verify E-Mail Addresses Through DNS - false

Send E-Mails - true

 

Setting should be normal which make me feel really confused, please help~~~ :'(

 

Thank you! :D
