how to create email address for newly registered user and configure that email at smtp

hi

i'm at admin/settings/smtp and configured an email to use to send emails from the site. i have printmail module installed and when i click on 'send a page to friend' i'm taken to a form and there "sender e-mail', 'recipient e-mail', 'message' fields are there. sender e-mail is already filled out after receiving the email address of the logged in user. if i click submit the e-mail only gets sent out if the current logged in user's e-mail is configured at admin/settings/smtp. and there can be only one email that can be configured at admin/settings/smtp. for all users other than the one user whose email has been configured at admin/settings/smtp receive an error message saying
"Unable to send e-mail. Please contact the site administrator if the problem persists."

is there a way i can create an email for a newly registered user at my host and configure that email at smtp so that user will be able to send emails from the site
