I'm using my mailserver as an IMAP mail server. Installed Dovecot, fetchmail and sendmail. Put the local network in /etc/mail/acces to allow relaying for the users in the local network. Now I would like to send mail from the outside (internet) and use this server as a send mail server, without risking to open the gates for everybody to relay. I have no fixed WAN-IP. I use dyndns.org. How can I do this without worry. Thanks for help -- Roland Brouwers C.A.T.
