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.

Yes, it's possible. I use postfix virtual domains to direct entire subdomains to my personal mailbox, which I then host with dovecot-imap. For spam reasons I cannot in practice recommend redirecting an entire domain like @blahblahblah.com but subdomains like @addresses.blahblahblah.com or something like that works fine (and can be very secure, since if you're using it for account signups it makes it very difficult to predict what email you've used for a given account making it difficult for someone attempting to reset your password or attempt to find re-used passwords across different accounts for example).
I will agree with everyone else that starting a new mail server, especially in this day and age, is a challenging and complicated task with many obscure and tedious steps and constant maintenance and vigilance and little room for error. I have been doing this for over 20 years, and even I have been blacklisted countless times for small mistakes and configuration errors, and while an increasing number of blacklists are automatic and will eventually remove you once the problem is fixed, getting off certain blacklists is difficult and in the case of some of them, effectively impossible without paying money or coordinating with your ISP (and often paying money to them instead to vouch for you, or to give you permission to even run an un-blocked email server in the first place).
Running a mail server requires a massive investment in trust and reputation, that presents a significant and possibly insurmountable barrier to entry for a novice, and it is absolutely jumping into the very deepest possible end of shark infested waters. I won't say it's impossible, but you're going to have a very difficult time if you expect to be able to use it even for full-time personal use.
I will say that receiving is usually easier than sending, so if you just want to receive emails on your own server and store them there, and then send using an "official" address (not on your server) that might work better. But it's still super complicated, and having a setup like that can make it even more complicated, so this is still really not something I'd recommend if you're new at self hosting and networking and stuff.
There are lots of cool things you can do so easily with self-hosting, this is absolutely one of the hardest, and while it is rewarding and valuable in its own way, I would say it's far from the most rewarding or valuable thing, and considering the difficulty, it's almost certainly not the first thing you should be attempting.
