Question Is it possible to trigger a script on receiving email with postfix

[EBardoul]

Server operating system version

Debian 9 64bits

Plesk version and microupdate number

Plesk Obsidian Web Pro Edition Version 18.0.44 Update #3

I need to trigger a php script on receiving eMail on a certain address.
I found this solution
Run script on receipt of email
but I am not sure about adding /etc/postfix/address.txt and doing postmap /etc/postfix/address.txt and how it could affect postfix and /var/spool/postfix/plesk/virtual.db or not.
OR may be there is a better solution ?
