===Upgrade installation 1===

 Configure Postfix to automatically add SMTPUTF8 when sending to EAI Address using Pipe Filter

Make sure you have a working Mail server using the base installation


Install php5-cli, the script is using  PHP
<syntaxhighlight lang="bash">
sudo apt-get install php5-cli
</syntaxhighlight>

get the script and place it in /etc/postfix
<syntaxhighlight lang="bash">
   cd /etc/postfix
   sudo wget https://raw.githubusercontent.com/padillareyj/eaifilter/master/eai-add-smtputf8.php
</syntaxhighlight>

Update ownership and permission
<syntaxhighlight lang="bash">
    cd /etc/postfix
    sudo chown root:root eai-add-smtputf8.php
    sudo chmod +x eai-add-smtputf8.php
</syntaxhighlight>

Update your master.cf, the following will filter all incoming mail coming from port 25 and resend to port 10025(accessible locally only), It will append the SMPTUTF8 in MAIL FROM command is executed. MAIL FROM: <MAIL> SMPTUTF8 
<syntaxhighlight lang="bash">
smtp      inet  n       -       -       -       -       smtpd -o content_filter=eaifilter -o receive_override_options=no_header_body_checks
eaifilter unix - n n - - pipe flags=RXhu user=nobody argv=/etc/postfix/eai-add-smtputf8.php -f ${sender} -d ${recipient}
127.0.0.1:10025   inet  n       -       n       -       -        smtpd
        -o content_filter=
        -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks,no_milters
        -o smtpd_helo_required=no
        -o smtpd_helo_restrictions=
        -o smtpd_data_restrictions=
        -o smtpd_client_restrictions=
        -o smtpd_sender_restrictions=
        -o smtpd_recipient_restrictions=permit_mynetworks,reject
        -o mynetworks_style=host
        -o in_flow_delay=0
</syntaxhighlight>


Update main.cf
<syntaxhighlight lang="bash">
content_filter =eaifilter:[127.0.0.1]:10025
</syntaxhighlight>

===Upgrade installation 2===
Configure Postfix to modify sender's email address when sending to Non-EAI enabled mail server using Pipe Filter
Make sure you have a working Mail server using the base installation and skipped Upgrade installation 1.


Install php5-cli, the script is using  PHP
<syntaxhighlight lang="bash">
sudo apt-get install php5-cli
</syntaxhighlight>

get the script and place it in /etc/postfix
<syntaxhighlight lang="bash">
   https://github.com/padillareyj/eaifilter/blob/master/eaifilter.php
</syntaxhighlight>


This filter will check outgoing mail server, if the server does not support SMTPUTF8, it rewrites the address of the sender to a non-ascii format base on alias mapping.

<syntaxhighlight lang="bash">
smtp      inet  n       -       -       -       -       smtpd -o content_filter=eaifilter -o receive_override_options=no_header_body_checks
eaifilter unix - n n - - pipe flags=RXhu user=nobody argv=/etc/postfix/eaifilter.php -f ${sender} -d ${recipient}
127.0.0.1:10025   inet  n       -       n       -       -        smtpd
        -o content_filter=
        -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks,no_milters
        -o smtpd_helo_required=no
        -o smtpd_helo_restrictions=
        -o smtpd_data_restrictions=
        -o smtpd_client_restrictions=
        -o smtpd_sender_restrictions=
        -o smtpd_recipient_restrictions=permit_mynetworks,reject
        -o mynetworks_style=host
        -o in_flow_delay=0
</syntaxhighlight>

Update main.cf
<syntaxhighlight lang="bash">
content_filter =eaifilter:[127.0.0.1]:10025
</syntaxhighlight>


===Upgrade installation 3===
Multiple virtual domain support
Info:

Info:

* You need to have at least a base installation
* MySQL does not work for Virtual Domains, the domain and user return as garbled text in the authentication.
* Virtual Alias Domain is used instead (it works).
* This should work for Ubuntu, Centos and Freebsd

<syntaxhighlight lang="bash">
sudo postconf "virtual_alias_domains = yourdomain1.com yourdomain2.com yourdomain3.com youretc.com โดเมนคุณ.ไทย"
sudo postconf "virtual_alias_maps = hash:/etc/postfix/virtual"
</syntaxhighlight >

edit or create  '''/etc/postfix/virtual'''
<syntaxhighlight lang="bash">
yourdomain1.com                     DOMAIN
someuser@yourdomain1.com            user1

yourdomain2.com                     DOMAIN
anotheruser@yourdomain2.com         user2

yourdomain3.com                     DOMAIN
admin@yourdomain3.com               user3

youretc.com                         DOMAIN
admin@youretc.com                   user1

โดเมนคุณ.ไทย                        DOMAIN
แอดมิน@โดเมนคุณ.ไทย                  user1
</syntaxhighlight >

Update your changes
<syntaxhighlight lang="bash">
sudo postmap /etc/postfix/virtual
</syntaxhighlight >
