domain settings on dsl with dynamic IP and NAT (and postfix issue)
One thing I've never been sure of is what to set the domain to on my Linux box. I'm on verizon dsl with a dynamic IP and PPPOE. I just got a dyndns.org domain with a different hostname than what I have for the machine. I set up the machine to run spamassassin (and to experiment). Machine name = grizzy Dyndns.org address = dibb.homelinux.net Email = jntdibb@bellatlantic.net What should I be using for the domain name? Specifically I'm having trouble with some part of postfix or spamc/d. I believe an hourly cron job is trying to send mail to 'root' which causes the following in maillog. I can send my postfix/main.cf file if anyone is interested.

Overall, mail handling seems to work. Stuff gets out, stuff comes in, spam gets tagged. But I need to clean some of this up.
Again, more investigation and I found the problem. Need to set the root: alias to a non-root user in the aliases file. Postfix won't deliver mail to the root account. Also, I set the domain info to bellatlantic.net. Seems to do the right things so far. ( I figure if I post what I've found, it may help someone else, right?)
