Hi!! I have a script in PHP that should send an e-mail from a specific e-mail account, let's say <mailto:mguirao@xxxxxxxxxxxx> mguirao@xxxxxxxxxxxx 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, Miguel Guirao Servicios Datacard www.SIASA.com.mx
