[PHP-DB] sending e-mails

['Miguel Guirao']

Hi!!
 
I have a script in PHP that should send an e-mail from a specific e-mail
account, let's say  <mailto:[EMAIL PROTECTED]> [EMAIL PROTECTED]
to a customer's e-mail account, using the smtp_mail.inc class of PHP.
But, Do I need to authenticate first in order to send the e-mail? If so,
how?
 
Best Regards,
