As in this picture, l don't want to remain a sender/recipient, but an address in itself. So that l can house multiple senders/recipients.
Would that be possible ?

No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

I think the last time when you could do that was 25 or 30 years ago. Nowadays, you're just going to enter a world of endless pain, suffering and frustration.
You can do it as an experiment if you want to experience how bad it is. Do it on something isolated that you won't mind setting fire to afterwards.
So actually it's not as bad as that. I feel like I should write a guide.
Absolutely the hardest part was getting a static IP. More on that in a second.
Exim and dovecot are very, very mature pieces of software. Exim is difficult to configure, but once you get there, it doesn't ever change. Now that the AI tools have gotten good, you can learn and configure it quite quickly.
For spam- life is so much better with pfsense running pfblocker. Also,bi set up a fail2ban feed to pfblocker to block IPs spamming,brute forcing, or otherwise misbehaving. Much of this already existed in fail2ban and I just have it dump its blocklist to text via a cron job that pfblocker loads.
The good IP is the hard part. For a while I just paid for one, it was about $20 more here for business class Internet that came with an IP. Eventually I cut costs.
You can do this basically two ways. Just get a VPS and install the mail server there, or get a VPS and install opnsense or pfsense there, with a VPN tunnel back home to your mail server. Haproxy handles it and wireguard is really reliable. I did hit a snag here because Google are buttheads and blocked the IP I had - literally no one else does. I actually don't have too many people who use gmail that I contact so it has only been a tiny problem. But the first IP I had worked perfectly for years.
You need to set up SPF, dkim,certificates etc. But these are just text strings and let'sencrypt...once all set up it just stays that way. Apply updates when released and enjoy your own email server, which is awesome.
