Auto-Learn spam/ham installer

@djav1985 created a repository with the software here:

A couple of months ago I sent two PRs to fix two bugs and he merged them but are not in the main branch so if you install from his repo, you will have issues.

Till @djav1985 can add the fixes to main branch, you can download it from my fork (it has also a new feature ro remove duplicated spam/ham messages).

To install, using root user, execute these steps:

Note: If you don’t have git installed, install it with apt install git

cd /usr/local/src/
git clone
cd v-hestiacp-sieve/
chmod +x

And that’s all.
