My webhost has recently changed the email security settings due to an exploit. I use x-cart, now none of my emails sent by the site (order confirmations to customers/order dept, profile changes, etc..). They say its a temporary solution to the email exploits, so I'm looking for a temporarly solution for sending mail with the site.

"Emails via apache
Emails which are sent without authentication via the SMTP server will not be sent. If you use a script which uses the mail() format, you must authenticate yourself prior to sending these messages through the SMTP server with a username/password for an account which you have created."

Does anybody happen to have a modified x-cart that will allow smtp auth or something to allow me to continue sending emails like normal again for the time being? I've checked out phpmailer, but I do not have access to php.ini. How likely would it be that my host has phpmailer included in the php.ini file? Thanks
