	You have several options, all of which present their own set of issues.

	First off is SMTP AUTH, which not all clients support (most of the major
ones do)  For more info see: http://www.sendmail.org/~ca/email/auth.html

	Second is Pop before SMTP, for which there is no standard, more info at:

HTH, and Good luck
