As far as I know I'm not running named. I am not using
sendmail (at least it was never my intention) for the
host name. I really don't have a qualified domain
name.
This is where I'm a little bit fuzzy.
If I named this machine "bonsai", does this something
got setup to send mail to this domain?
In general, sendmail expects any system that sends or recieves mail to be a legitimate host with a legitimate internet address and fqdn - and resolvable forwards and backwards.
Most of this is justifiable for security reasons, but it's also just part of the culture.
