-Save the changes.  It remains to compile and install Exim.
-<code bash>
-make
-su
-make install
-</code>
-After the installation is complete, you need to create a symbolic link, this will do the following:
-<code bash>
-ln -fs /usr/local/exim/bin/exim /usr/lib/sendmail
-ln -fs /usr/local/exim/bin/exim /usr/sbin/sendmail
-ln -fs /usr/local/exim/bin/exim /usr/bin/mailq
-ln -fs /usr/local/exim/bin/exim /usr/bin/runq
-</code>
-After that you want to remove from the object files Exim table name and line number information for this issue:
-<code bash>
-strip /usr/local/exim/bin/exim*
-exit
-</code>
-Before configuring Exim, you need to create a database, the user and the appropriate table for this issue:
-<code bash>
-/usr/local/mysql/bin/mysql -u myadmin -p
-</code>
-Result
-<code>
-Welcome to the MySQL monitor.  Commands end with;  or \ g.
-Your MySQL connection id is 3760 to server version: 4.1.10a-log
-Type 'help;'  or '\ h' for help.  Type '\ c' to clear the buffer.
-mysql>

-Create the database.
-<code mysql>
-mysql> CREATE DATABASE exim;
-mysql> GRANT ALL PRIVILEGES ON exim.* TO sqlmail@localhost
-    -> IDENTIFIED BY 'my_password' WITH GRANT OPTION;
-mysql> quit
-</code>
-When the database and user created, you need to create the table structure, and enter data about users.  You can do this in the MySQL console, but we will create exim.sql file, which will then create us everything we need.

-If no errors are found, go on ... Now we need to check whether you will be delivering messages to external users, for this issue:
-<code bash>
-exim -v someuser@msn.com
-From: admin@sharewiz.net
-To: someuser@msn.com
-Subject: Testing Exim
-This is a test message.

-At this stage, we are convinced that Exim is correctly configured and working, now it is necessary to check the SMTP authentication, but before us be editing.  SMTP authentication is necessary when sending us soobschny with virtual host (if you have any) or when the user is outside the office, send mail through your account.  I do not use authentication for intranet.  Therefore, change in the file /usr/local/exim/configure line
-<file exim>
-hostlist   relay_from_hosts = 127.0.0.1
-на
-hostlist   relay_from_hosts = 127.0.0.1 : 192.168.10.0/24
-</file>
-Run Exim, by typing:
-<code bash>
-/usr/local/etc/rc.d/exim.sh start
-</code>
-To verify authentication, we need the converter, install it from ports:
-<code bash>
-cd /usr/ports/converters/mmencode
-# make install
-# exit
-</code>
-Form a line PLAIN authentication (Netscape), for this issue:
-<code bash>
-printf 'admin@mydomain.ru\0admin@mydomain.ru\0my_password' | mmencode
-</code>
-Shows
