Exim come with default configuration we will change to mach system settings /etc/exim/exim.conf.
$ sudo prt-get depinst mailx
Exim creates a key for you if you just copy exim.conf and start daemon;
# cp /home/silvino/data/git/c9/c9-doc/core/conf/exim/exim.conf /etc/exim/exim.conf
# sh /etc/rc.d/exim start
SSL certificate /etc/ssl/certs/exim.crt with key /etc/ssl/keys/exim.key for host c9.core created
#
Manually create a private key;
$ sudo mkdir /etc/ssl/keys
$ sudo openssl req -x509 -newkey rsa:2048 -keyout /etc/ssl/keys/exim.key -out /etc/ssl/certs/exim.cert -days 9000 -nodes
Generating a 2048 bit RSA private key

writing new private key to '/etc/ssl/keys/exim.key'

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.

Country Name (2 letter code) [AU]:PT
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) []:
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (e.g. server FQDN or YOUR name) []:core.privat-server.net
Email Address []:postmaster@core.privat-server.net

# chown mail:mail /etc/ssl/keys/exim.key # chmod 0600 /etc/ssl/keys/exim.key # chmod 644 /etc/ssl/certs/exim.cert
Exim come with default aliases we will change to mach system settings /etc/exim/aliases;
# Default aliases file, installed by Exim. This file contains no real aliases.
# You should edit it to taste.
# The following alias is required by the mail RFCs 2821 and 2822.
# Set it to the address of a HUMAN who deals with this system's mail problems.
postmaster: c9admin
# It is also common to set the following alias so that if anybody replies to a
# bounce message from this host, the reply goes to the postmaster.
mailer-daemon: postmaster
# You should also set up an alias for messages to root, because it is not
# usually a good idea to deliver mail as root.
root: postmaster
# It is a good idea to redirect any messages sent to system accounts so tha
# they don't just get ignored. Here are some common examples:
bin: root
daemon: root
ftp: root
nobody: root
operator: root
uucp: root
# You should check your /etc/passwd for any others.
# Other commonly enountered aliases are:
#
# abuse: the person dealing with network and mail abuse
# hostmaster: the person dealing with DNS problems
# webmaster: the person dealing with your web site

Tony Finch publish a nice configuration reference.
File /etc/exim/alias rewrite addresses when receiving, return_path and headers_rewrite rewrite addresses in header (envelop) while main rewrite apply rewriting to all.
Test sender rewriting;
# exim -brw bob@box
# exim -brw bob@remote.com
Test routing;
# exim -bt bob@box
