I do?! This IS an old box (2.2 kernel). I'm dialing my ISP without
benefit (shudder) of an external firewall, just the internal ipchains.
I point /var/spool/postfix/etc/resolv.conf at my ISP's suggested DNS:
domain lan
nameserver 209.102.124.14
nameserver 209.102.124.15
(I deliberately chose a domain name that wasn't routable to prevent
collisions. Seems to have worked so far. Hope that doesn't confuse
postfix.)
This IS low volume. All I'm trying to do is send one message a day to
a few friends.
