</pre>
* Send mail.example.com.csr to a Certificate Authority to have a signed certificate created, then create the certificate file:
<pre>
vi mail.example.com.crt
</pre>
#* *NOTE*: I use StartSSL, but there are many different CAs to choose from.
* Once the SSL certificate has been created on the mail server, download and add the intermediate certificate to the SSL certificate:

<pre>
service clamav-freshclam start
service clamav-clamd start
</pre>
*NOTE*: It may take a little while for “freshclam” to download the files. So, if you see a message like “Missing /var/db/clamav/*.cvd or *.cld files. You must run freshclam first” you may not be able to start the clamd daemon (clamav-clamd) until that finishes.
h2. Setup Maia Mailguard

# Base URL to Maia's PHP scripts
$base_url = "https://mail.example.com/maia/";
</pre>
* Run configtest.pl executable:
<pre>
perl /usr/local/share/maia/scripts/configtest.pl
</pre>
* Load SpamAssassin rules:
<pre>
sa-update
su - vscan
perl/usr/local/share/maia/scripts/load-sa-rules.pl --debug

...
$purifier_cache = '/usr/local/www/maia/web';
...
$address_rewriting_type = 4;
...
$auth_method = "pop3";
...
</pre>

</pre>
#* Add the following:
<pre>
server {
listen 80;

fastcgi_param PATH_INFO $fastcgi_script_name;
include fastcgi_params; # include extra FCGI params
}
}
</pre>
* Restart nginx and php-fpm:
<pre>
service nginx restart
service php-fpm restart
</pre>
* Visit https://mail.example.com/maia/admin/configtest.php and verify everything is working.
* Create maia run directory:

...
</pre>
* Set Maia-Mailguard to start at boot and start it now:
<pre>
echo 'maiad_enable="YES"' >> /etc/rc.conf
service maiad start
</pre>
* Visit https://mail.example.com/maia/
#* You should be greeted with a login screen. If so, great! Let’s log in and acquire admin privileges…
*NOTE*: If your images do not load, you’ll need to edit the /usr/local/www/maia/smarty.php file and delete the leading slash from the “/themes” bit on line 102. So, it should look like this:
<pre>
$this->assign('template_dir', 'themes/'.$theme.'/');
</pre>
* Instead of https://mail.example.com/maia/login.php (The default), visit https://maia.example.com/maia/login.php?super=register
#* And and log in with any currently existing virtual user. user (Most likely the user you added with Postfixadmin earlier). Be sure to use a full email address to log into Maia-Mailguard. This guide uses superadmin@example.com. IE: username@example.com. That user will now have admin privs via Maia (So, be careful which user you choose).
* Once logged into Maia-Mailguard as an administrator, click the “Admin” link at the top of the page (Key-shaped icon). From the “Administration Menu” click “System Configuration“. Each mail server will want different settings for their setup. However, there are some things you should be aware of:
*# Make sure that *ANY* file name (With the exception of the logo image) listed for any option is listed with it’s *FULL PATH*.
*# The “Mail size limit” setting should not be higher than what you set your MySQL’s max_allowed_packet in /var/db/mysql/my.cnf.
*IMPORTANT*: For each domain you create using Postfixadmin or any other way you may create it, Maia needs to know about it in order to create users. This might seem like a redundant issue, but it really makes a difference and here’s why. When Maia recieves mail for a user that doesn’t exist, it uses the default domain’s (@.) settings. This is fine. However, if it considers that mail to be spam when it is not, the user cannot retrieve that message later being as the default settings don’t house mail for a non-existant user.
*+So, be sure to add any domain you add via PostfixAdmin to Maia-Mailguard as well.+*
* Edit main postfix file:
<pre>
vi /usr/local/etc/postfix/main.cf
</pre>
#* And modify the following:
<pre>
...
# Maia-Mailguard
#
content_filter=smtp-amavis:[127.0.0.1]:10024
