Exim will allow you to do smtp authentication (so will any modern MTA). http://www.exim.org/exim-html-4.00/doc/html/spec_32.html A quick summary, is the MUA (mail client like Outlook) will authentica with the MTA (mail server like exim) using (for instance) username/password. If authentication is sucessful, the MTA will relay the mail. So, this allows unknown IP address -with- proper authentication to relay email to then Internet at large. -- Bob Tanner <tanner at real-time.com> | Phone : (952)943-8700 http://www.mn-linux.org, Minnesota, Linux | Fax : (952)943-8500 http://www.linuxjustworks.com | Linux Just Works!
