I've been using Postal Server for 2 years ( https://docs.postalserver.io/ ) sending around 50k emails / day without any issue.

Just make sure you set up everything (SPF, DKIM, DMARC) correctly, including the PTR reverse lookup of your server ( really important ).

Key tip: warm up your ip(s). I use mailreach.co ( it has a USD 25/m cost ), reached near 100% deliverability in a month.

I now have barely have any maintenance to do. It just works.

I don't know much about mail server and this must be how people feel when they watch Hollywood movie hacker moment

It's mostly DNS records. Postal Server has good documentation and tools helping you set up quite everything in their UI.

It seems Stalwart also makes it easy in their UI based on the gif in the post. You can see at some point a list of DNS entries to update.

The only missing thing in all these is the PTR record which needs to be set up at the hosting level.

A good tool to check if everything is OK is https://www.mail-tester.com/

It's not that hard, and less work than it used to be.

Most of the movie hacker moment is often people who want to setup and configure and maintain each component of an email server manually, compared to a reasonably compiled package to allow more administration of it.

If this package isn't someone's cup of tea, products like MDaemon continue to exist and crush it for self-hosting email using a windows server just fine for the past 15-20y.

Postal is not very well maintained, I don't think it's a wise choice to use it if alternatives exist.

[julienmarie]

Why? Last commit on main branch was 3 weeks ago.

It's not perfect ( a bit slow ), but really easy to set up and configure. Which was the main draw.

Thanks! Wdym by warm up your ips? How does mailreach relate to the setup?

[julienmarie]

What email warming services do is they create activity between your server and hundreds of email accounts they manage on major ISPs and they make sure to click on "not spam" if it falls under spam, and try to bring your emails to the main inbox.

It's a bit of a grey area thing in fairness.

If service providers don't already detect such users it's quite guaranteed that they will in the future.

Trying to game the system is frowned upon in all cases.

[tetrisgm]

Oh cool. So that's what mailreach does? Sounds great tbh

[xcdzvyn]

Sounds malicious.

Not inherently. Whole IP blocks seem more or less black-listed by Google and Microsoft. So if you happen to get a server in that block, you can't send email.
