ProtonMail. 100%.

I set up custom DNS and catchall so yourcompanyname@saltycowboy.org is really how I filter spam.

Please note, saltycowboy.org isn't really my domain.

unless you realllllly enjoy self hosting your email, IMO it’s just not worth it anymore with the state of things. I use Fastmail and could not be happier.

I use fastmail, and I enjoy it a lot. Their masked email is very nice as well, and integrates with bitwarden. So quite convenient to use my personal domain for stuff where my identity matters, and use masked @fastmail addresses for more disposable stuff.

The only thing that ticks me a tiny bit is that their mobile app doesn't have offline mode; but you can use imap client or w/e, so it's not too much of an issue.

Also hear good things about protonmail; I would consider it if I didn't already use/trust fastmail.

im an old school email admin. i gave up on my personal exchange box for protonmail years ago.. multiple domains, lots of dns nonsense on my part. zero problems.

i highly recommend them.

https://mxroute.com/ is what I went with. They have a $99 lifetime plan. Semi limited, but worth it imho.

I use mailcow for self hosting.

Nowadays I'd recommend a simple postfix + dovecot setup. If you care about a web-UI and possibly some groupware functions put SOGo on top.

Fasmail + domain

I use docker-mailserver with sendgrid as smtp relay

I have used https://migadu.com/ for over a year now with no problems. Very happy with them. Setup is well documented.

Just switch to mail in a box.

I found myself in a similar situation last year. MXRoute's lifetime plan works well for those domains that just need basic email and not a lot of storage.

Moved from a junky setup where I was forwarding my domain mail to gmail. And sending mail through gmail using the smtp server provided by my web host.

I was having too many issues.

I switched to fastmail. It is quite good. And you can get some free basic web hosting included with your paid service.

I use iRedMail but would I call it simple? No. Mail is such old tech that simple really isn't the word for it. Archaic, ancient and dying fits better. But it will take decades more to actually die. iRedMail is available as a single container, which isn't correct from a container perspective but makes everything a lot easier in my opinion. Of the various solutions I've tried it's the one closest to the goal of "It just works". The biggest downside is the manual steps often needed to upgrade version. Not to time consuming but far from "It just works".

I use Zimbra with an external email gateway that only accepts authenticated email. Zimbra is pretty heavy (it's intended to be a Microsoft Exchange replacement) but it at least has a huge amount of protection built-in to deal with spam and comes configured out of the box to not relay (well, outside of you setting up aliases and lists.)

That said, it's not hard to find "incoming email only" configurations that deliver to local mailboxes only, for most email servers. The thing to avoid is having a single server configuration that tries to do both - accepting external email and sending locally originated email out. The configurations do exist to do that, but they're confusing and tricky.

External email gateways... that bit is hard. I use a mail server I set up myself on a VPS. It does not listen on incoming port 25. It requires credentials. I did this largely because I was trying to send email out via Xfinity's customer email relay, but the latter kept upping the authentication requirements until one day Zimbra just couldn't be configured to use it any more. And each time they changed something, I wouldn't find out until I noticed people had clearly not received the emails I've sent out.

VPSes are problematic as some IPs are blocked due to spam. There's not much you can do about it if you're stuck with a bad IP, so if you can find a way to send outgoing email via your ISP's outgoing email server, do that. For Postfix, you can send out authenticated email using something like: in main.cf:

relayhost = [smtp.office365.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_use_tls = yes

and in /etc/postfix/sasl_passwd:

[smtp.office365.com]:587 example@outlook.com:hunter2

So in summary:

• Consider an email-in-a-box solution like Zimbra, I understand the wish to go for something light but it might make sense if your aim is just to control your own email
• Regardless of whether you do or not, use separate servers for incoming/outgoing email.
• For incoming email, lock it down to accept local email down if you're manually doing this rather than using an email-in-a-box solution like Zimbra.
• For outgoing email, use authentication and avoid it listening on port 25. Consider either directly using your ISPs, or if that's not practical, configuring your outgoing email server to relay in turn to your ISP (see above for how to do this.)

Good luck.

Oh no! I'm sad to see that you've run into troubles :(.

There are other "fully put together" solutions like mailinabox and mailcow, that could be worth looking into for you. I haven't used them personally, but you might find them worth looking into. I'd never heard of mailu before, actually.

Totally understand the desire to just move to a hosted solution after running into these problems, but even if you do that I think you should keep running a mail server in the back of your mind for the future

you've already learned a lot about it I'm sure, and maybe with a bit more experience you'll be ready to tackle it again :).

I don't actually use any of the fully assembled solutions like mailinabox, and I wonder if in the future it might be a good idea to try configuring everything manually. You already have some familiarity with how mail works at this point, and having more control over the setup and how everything fits together might actually work out for you. Personally I'm running an OpenSMTPD + Dovecot mailserver and having a great time. I'd recommend it.

Either way, I think you should keep using a custom domain for e-mail because then you have options in the future :).

Protonmail. That's what I use connected to my own domain.

Personally using Ionos.
Not bad experiences so far but you need to watch out at times and check your invoices.

Throwing my hat in for Protonmail.

Yes https://cloudron.io + Contabo

Mailcow dockerized.

I hosted email professionally for over a decade... and I can't recommend getting back into the business. At that time we were using Qmail, although I also have experience managing Exim and Postfix. About 90% of incoming email remains spam.

For outgoing email for things like server cron mail, a stub service like msmtpdcan be used to receive local mail and forward it to to a local service.

To receive and host email, Fastmail is good.
