This is my first post in the maillist (I hope I did it right - I'm sure someone will let me know if I didn't :) I'm so green to linux that just reading this may give you diarrhea. I just setup SuSE 9, postfix and qpoppoer - I must admit, SuSE did most of the work. If I can do it then there is hope for a free world. My only hiccup is my semi-static IP address to my NAT unit via DSL - it changes every few days. Is there a way for the server to update 'main.cf' file to the correct proxy interface and reload postfix when the WAN IP changes? I'm not even sure how to detect when my ISP expires my address. BTW: it took me quite some time to figure out that the proxy interface needs to be the WAN and not the LAN address. Thank you. Josh Joslyn
