This article will help you install Artica SMTP on a Debian 10 system that has already been set up.
For example, on a VPS server.
Please note: even if Artica is installed on an already installed Debian system, avoid installing Artica on a mail server you're already using.This is because artica will modify the system as it sees fit, and you won't be able to go back.
So prefer an unmodified Debian system.
