Catchall for postmaster/hostmaster/abuse

[Skale, Franz]

Hi Jan,
i have a multidomain-setup and can therefore give you some advise.
First of all you have to create one postmaster in the primary domain.
I chose a mail enabled posix user typ because i want system mails 
(apt-listchanges etc. etc.) to also be delivered. (Of course You have to 
configure pam-ldap and nscd for that type)
Then i added aliases like abuse at domain.com, postmaster at domain.com, 
hostmaster at domain.com etc.
kolab chooses that email address for last resort (if it don't find  
matching alias in the destination domain).
Add the primary.address to /etc/aliases:
# /etc/aliases
mailer-daemon: postmaster
postmaster: root
nobody: root
hostmaster: root
usenet: root
news: root
webmaster: root
www: root
ftp: root
abuse: root
noc: root
security: root
clamav: root
root: postmaster at domain.com

Run: newaliases.

Done

Rgds.
Franz
