Linux Admin for Postfix / Dovecot Mailserver Setup and Data migration

We are searching for a Linux Admin who knows Postfix / Dovecot / Rspam / Sieve etc.
As we have other tasks todo and would like to outsource this to someone who we also can rely on in the future.

Your Task is to setup a Mailserver using:

Postfix / Dovecot / Rspamd / Mysql / Vimbadmin / Sieve / Roundcube
with Fail2Ban and whatever else comes to mind with security purposes.

SSL should be implemented and automatically renewed with Letsencrypt.

We are aware that there are tutorials out there and chatgpt easily blueprinting this. But we need someone who has some
understanding of what he is doing.

If there is 2Factor possibility working you know of, we would like to implement these also.
(As for this writing neither ChatGPT or Google show a solution... so do not worry about it if there is none) 

After successful installation the virtual server image will be frozen in the basic setup.
Then customer data has to be migrated to new server. (Mails, Users, Sieve Data etc.)

Please apply with some kind of history and reason to your application.

Greetings
