postfix issue. First of all, the upgrade appended lines (without asking
me) to /etc/postfix/main.cf. They look innocent enough, but it's still
Very Bad Form (TM).

The real issue is that whereas before postfix was able to find my
relayhost by name by looking in /etc/hosts, it now seems to be insisting
on doing a DNS lookup (which fails). Quick fix was to put the IP address
in main.cf in place of the hostname.
