Okay.. Getting closer now..
This is in the post-install file:
BTW: Check your $ALIASES file and be sure to set up aliases
that send mail for root and postmaster to a real person, then
I guess they are talking about the /etc/aliases
In this I have 5 times postmaster.
I'm about 99% sure that I need to change the mailer-daiemon postmaster
falko.. can you confirm this?
