Consider still using sendgrid, AWS ses, or some other service for outbound mail. Incoming email isn't bad, but outgoing email is where your more likely to run into issues with your IP being blacklisted/etc

I've run mail servers professionally since the 90s, I run my own mail via Mailcow. Be sure you know what you're doing on things like SPF and DKIM or you're going to have a bad time.

I second mailcow. It’s what I’ve been using for years and it’s pretty great.

One thing I’ll add is before you take the plunge, make sure your VPS address isn’t on a block list somewhere. Pay a visit to mxtoolbox.com and you should find some resources there.

As everyone has mentioned SPF/DKIM/DMARC is the absolute minimum. If you're going to be sending your own mail then a PTR record is absolutely required. Also get registered dnswl.org and other whitelist sites. Be prepared to spend some time tracking down why the occasional email goes to spam. Then there's the onslaught of bots and hackers constantly trying to break in.

I've used Mailu to host my own mail server, and at my work we have a standard Postfix/Dovecot setup.

My recommendation is to use Fastmail, Proton, or some other service to save you the headache.

Good luck. I'm just paying $1 a month for my mail account. I like my solution to degoogle my mail more. Well to be fair, a lot of my mail still goes through google and then my new account since I haven't updated my mail everywhere.

https://github.com/docker-mailserver/docker-mailserver No web adminiatration you have to use cli but its small an feature rich

i'm using virtuamin myself, gives you a pretty decent interface to work with.

I use iredmail, but I also made sure I had access to port 25 and my IP wasn't on any blacklist. This is the very first thing you should do or all your efforts could be in vain.

Not self-hosting email anymore, but back when I did all the hype was https://mailcow.email.

I use docker-mailserver which is just one docker container running the basic services without the complexity of a webui an managing groupware

I'm really liking the look of stalwart, but it's quite new. Mailu seems to be pretty nice, good features and not too resource heavy. Mailcow does everything, but it's a 🐷.

OpenSMTPD. I run a private mail server for family, and it works flawlessly. No maintenance aside from backups and occasional OS upgrades. https://poolp.org/posts/2019-09-14/setting-up-a-mail-server-with-opensmtpd-dovecot-and-rspamd/

I also have a small domain that is relatively low traffic. A lot of the "all in one" software on the list you linked looks pretty cool, I can't deny.

What I found is that I make very few changes. I used to add mailbox aliases fairly often, but the fact is there are only two users and enabling the "+" syntax in addresses put a stop to me needing to make new aliases when I wanted a new address.

I just don't feel like I need a management interface. Because of this I've just sort of frankensteined my own setup together and I love it. It operates how I expect it to, and enforces the standards I care about to the extent that I desire (e.g. which SPF result codes am I ok accepting?).

• Postfix as SMTP/Submission server. I chose to go w/PAM based for outbound SMTP auth.
• Courier for IMAPS
• Dovecot for LDA (sieve is delightful)
• Snappymail for webmail (served by apache httpd)

If you are recently degoogled, then protonmail is a good option ( not self hosted) you get proton vpn, password manager, calendar , and 500GB drive storage.
