Hello Reindl Harald-2. I would rather remain with the Postfix MTA and DBbmail server, rather than switching to something else like Cyrus or Dovecot mail servers, as Postfix and DBmail are working fine. I can relay emails from within my local network, once I have enter the user's local IP address in "/etc/mail/access", eg (192.168.1.45 RELAY), and built the "access.db" file, but Postfix will not relay email coming from my IPhones out in the internet.
Before switching to Postfix and DBmail, I used sendmail MTA, and the Cyrus email server. I had local IP addresses entered in the sendmail /etc/mail/access file, which I used to build the access.db file as follows: portmap hash /etc/mail/access.db < /etc/mail/access Postfix seems to be using Sendmail's access.db; because, when I add a new user, I must include their local ip address in the /etc/mail/access file and build the /etc/mail/access.db before the new local user can sent out emails.. I though that was kind of strange, but that how it works for local users. However, Postfix is refusing to relay emails from the iPhones that connect to my mail server from outside networks. This is a good thing, as I don't want to be an open relay. I just need some way to let Postfix know that the iPhones should be trusted for relaying emails. That where sasl comes in. Postfix will recgonize emails coming from my roaming iPhone users, who connects from an outside networks, if the iPhone connect using sasl. Thanks for your information, though.
