Preserve custom settings in different config-files or templates

**m.mirzayev** · Jul 7th 2015

I'am using some custom settings on following files and realized that my customized files are overwritten with standard ones when upgrading i-MSCP (upgraded i-MSCP from 1.2.8 to 1.2.9 today).
Files customized by me:
- /etc/postfix/main.cf
......added different tweaks to prevent spam
- /var/www/imscp/gui/themes/default/reseller/navigation.php
......added variable 'visible' => '0', to sections hosting_plans and statistics to make them invisible for reseller
- /var/www/imscp/gui/themes/default/client/navigation.php
......added variable 'visible' => '0', to sections statistics and webtools to make them invisible for client
- /var/www/imscp/gui/themes/default/client/mail_add.tpl
......added a <span>@</span> infront of <select name="domain_name" id="domain_name">. Some clients added an @ into the textfield which is only for the mailadress when adding a new mailadress for example 'info@' in textfield.

I would like to know if there is any possibility to preserve this customizations. After updating i-MSCP i loose all this custom things and need to add them every time.

Thanks in advance for all your support.

Hello ;

I'll give you the procedure to follow. In order:

postfix main.cf and master.cf:

The standard way with i-MSCP is to create a listener file which will re-apply your custom configuration parameter automatically on update.

You can use that listener which has been created for that purpose: https://github.com/i-MSCP/imsc…tfix/10_postfix_tuning.pl

About the theme:

Again here, the better way is to create a listener which will copy your modified in the production directory once the update is done.

See that thread which talk about a listener that exactly do that: Dir->rcopy invalid dirhandle
