* The mail setup is confusing. I have a router/server/smarthost
bksys.at=188.8.131.52. The notebook is elke.bksys.at=192.168.0.8. I believe
some setting will go in the envelope sender so I tried to avoid elke.bksys.at
as envelope senden as 192.168.0.1 is a private IP address and I put bksys.at
there instead. But I ccied this mail to firstname.lastname@example.org which was
undeliverable, because IMO the notebook believes it is the destination point
for email@example.com but there is no bernhard here, only at bksys.at. So now
I tried to keep the 'mail name' empty, but it seems to default to
'localhost.localdomain', which is undesirable, too, because it is invalid as
Hmm, but elke.bksys.at worked. The envelope sender was firstname.lastname@example.org when
I used kmail. I can't change exim from 'EHLO localhost.localdomain'.
'elke:/etc/exim4# grep -ri localhost.localdomain *' yields nothing.
