Installing mailutils using apt-get without user intervention

问题

While installing mailutils on ubuntu 12.04 using apt-get, there are 2 instances when manual intervention is required, first to select the site configuration and secondly to enter the hostname of the box. Is there a way to automate the installation? I need to install the package on many servers and being a n00b sys admin, I haven't been able to find a solution yet. I can make and install from source, however it has other problems. Thanx.

You can use debconf-set-selections to pre-select answers :

$ debconf-set-selections <<< "postfix postfix/mailname string your.hostname.com"
$ debconf-set-selections <<< "postfix postfix/main_mailer_type string 'Internet Site'"
$ apt-get install -y mailutils

You'll likely want to look into debconf configuration specifics. Here's a link that should help.
