Either way is possible, but the Debian installer and Debian
documentation are written under the assumption that the
hostname is not a FQDN.

Good!

In general you should have the more qualified names to the left of
the less qualified ones. Thus "192.168.1.1 teufel.<domain> teufel".
You do not need 'teufel.localdomain' at all.

If you have an IP address 192.168.1.1 then use that instead of
127.0.1.1.
127.0.0.1 localhost.localdomain localhost
192.168.1.1 teufel.hartford-hwp.com teufel
If that does not work then some _other_ program is misconfigured.
Perhaps it will help if I show you my configuration files.
These are on an Ubuntu system but that should not make any
difference. This is a laptop system that is usually configured
using DHCP. When I move from one location to another I change
"relayhost" in /etc/postfix/main.cf to a different value.
