I am new to Drupal hence apologies if this has been discussed already. Kindly point me to the solution in that case.
I have Drupal running on a hosted IIS7 platform. I am getting the "SMTP server response: 550 5.7.1 Unable to relay for 'email address'" error when I try to send mail during new user registration or the forgot password fuctionality.
I tried setting up the smtp details in the .htaccess file as well as in mail.inc but no joy there.
Since this is hosted at an ISP I do not have access to the mail server nor the php.ini file.
Any help would be greatly appreciated.
