Fair. Don't disagree with anything you're saying here. I should probably tighten up that line. What I really meant to say is that the average self-hoster who just wants to enable a few services to send email doesn't want to run a mail server. Different audiences, different (and both correct) answers. I set out to solve some pretty specific problems of my own but I'm genuinely curious how others have tackled these thi…

Only a sith self-hosters want to self-host absolutely everything.

Does postal still use outdated rails? That's the biggest issue I have with this project as a exposed web service and mail server is for me high risk especially with outdated software.

They seem to be on 7.2, which will get security patches until August this year: https://github.com/postalserver/postal/blob/8ef89606bc34146f... https://rubyonrails.org/maintenance Not great, but better than 6.x.

The links shows: gem "rails", "= 7.1.5.2"

I don't know rails well, but that sounds like 7.1 (that is unsupported) and not 7.2?

> Nobody wants to run a mail server in 2026. We do, and thats why we use Postal [1]. The more SaaS applications that self-host email the better. It forces the big guys, ie Microsoft, to improve their blocklists and not lazily block entire ranges. Yes its work contacting them occasionally, but it keeps the internet open. The alternative is an internet where they control it all. 1. https://docs.postalserver.io/

If the self hosters runs a mail server it can receive their transactional emails to themselves and they don't even need to care about delivery to gmail

> Nobody wants to self host email server. I do. Though I am self hosting it to have my personal email, being well... personal. Not for my company so maybe I am not the target. Interesting project though. I always felt missing API to just send emails from some script in my mail server.

Any UNIX-derived operating system has some kind of command-line utility for sending email messages (named mailx or mail or Mail).

I do not remember if I have ever used the GNU mail program that is available on Linux, but my e-mail server is hosted on FreeBSD, so I have used very frequently the FreeBSD CLI utility to send e-mail messages from scripts.

Moreover, all FreeBSD servers come configured by default to send automatically a variety of e-mail reports to the administrator, to inform about incidents or statistics, so there are a lot of examples of usage from scripts.
