hostname error installing postfix

when I try to install postfix with apt-get on my debian system I get this error:

Code:

Setting up postfix (2.1.4-5) ...



Postfix configuration was not changed.  If you need to make changes, edit

/etc/postfix/main.cf (and others) as needed.  To view Postfix configuration

values, see postconf(1).



After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

installation script returned error exit status 100.

my /etc/hosts currently looks like this:

Code:

debian:/etc/apache2# cat /etc/hosts

127.0.0.1      localhost

127.0.0.1      debian



# The following lines are desirable for IPv6 capable hosts

# (added automatically by netbase upgrade)



::1    ip6-localhost ip6-loopback

fe00::0 ip6-localnet

ff00::0 ip6-mcastprefix

ff02::1 ip6-allnodes

ff02::2 ip6-allrouters

ff02::3 ip6-allhosts

Any ideas?

OK I changed my hostname and domain, which took care of the hostname problem, but its still complaining about anything like {MTA_ANYTHING} in the curly brackets. I changed the main.cf to put actual values in to the hostname and domain fields, but there's a whole lot of those MTA entries in there and I don't know what most of them are. Whats up with it not knowing what to do with those entries? Smells like an unsatisfied dependancy to me, but what? I should also note that I am trying to install VHCS and this might be the VHCS version of main.cf? I dunno what the norm is. Here is what I currently am getting:

Code:

debian:~# dpkg --pending --configure
