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'.

E: Sub-process /usr/bin/dpkg returned an error code (1)


so I edited the file "/etc/postfix/main.cf" and placed the true name for:
myhostname
mydestination

at installation I named it "NagiosServer.local"
but it did not changed "myhostname" and placed it "NagiosServer.(null)" !!!
and also at this file for "mydestination" it wroted: 
mydestination = NagiosServer.local, NagiosServer.(null), localhost.(null), localhost

and I changed teh "null"s to "local" and tryed again and it is installed
and running like charm :)

tnx
