If you wish to remove the product from the system it was installed to, the procedure in the particular case would depend on how it was installed.
Standard installation method
If the product was installed from ZIP package (for example, using these guidelines for cPanel), you can simply remove the files from the directory it was unpacked to, nothing else needs to be done.
If you have created a database for the use with WebMail Pro, you can drop it using MySQL command-line client, tools like PhpMyAdmin or database manager offered by control panel software you use.
cPanel installer
Assuming the product was installed on cPanel using our cPanel installer (requires root SSH access), run the following command while in the directory you have unpacked installer to:
./installer -a remove
And in case if you have already deleted the installer - no problem, simply download and unpack it again per this documentation page.
DirectAdmin installer
If the product was installed on DirectAdmin, run the following command while in the directory you have unpacked installer to:
./installer -a remove
And in case if you have already deleted the installer - no problem, simply download and unpack it again per this documentation page.
Plesk package
To remove APS package installed on Plesk system, navigate to Applications section of your website management interface, locate WebMail Pro in the list and click "Remove".
If you have administrator access to Plesk and have uploaded Plesk APS package found at our website, you can remove it under Server Management > Tools & Settings > Applications & Databases > Application Vault.
Ubuntu/Debian package
If the product is installed from our APT repository, run the following command:
apt purge afterlogic-pro
The above assumes the standart Debian/Ubuntu package was installed. In case if this is about Nginx package, first you need to remove the product:

and then you can remove the installer package itself:
apt purge afterlogic-nginx
