Sendmail authenticated relay
I am administering a e-mail server running RHEL 5 with sendmail 8.13 and using dovecot imap most of the users are going to need to be able to send mail from their laptops and i have no idea what network they will be utilizing. How can I implement a secure form of authentication that will allow my users to receive and only relay with authentication? I have already tried using certificates but then my users cant recieve mail because senders cant authenticate.
