docker-mailserver VS mnm

I can recommend Docker mailserver (it also works with Podman). It is already pretty lightweight but you can even make it lighter and it has an active community as well as regular updates.

https://github.com/docker-mailserver/docker-mailserver https://docker-mailserver.github.io/docker-mailserver/latest/ https://www.programonaut.com/how-to-host-a-mail-server-with-docker-for-free-step-by-step/

Use https://github.com/docker-mailserver/docker-mailserver or mailcow . They both provide reasonable default setup for spam detection and even UI for adjusting settings.

" this docker based mail server looks pretty legit https://github.com/docker-mailserver/docker-mailserver "

Check https://github.com/docker-mailserver/docker-mailserver It has almost everything in a single docker image. Email is not the easiest to implement with container(s), but that project has managed it.

I set up docker-mailserver[0] Monday in ~6 hours, most of which were me trying to be fancy using podman instead of docker and dealing with SELinux. But then again I did choose it over mail-in-a-box for just that level of customization. Obviously I can't tell how reliable it will be in the long run yet, but since it's using the classic Postfix/Dovecot stack I expect it'll be pretty stable

TMTP a Internet protocol combining elements of email and the web\ (3 comments)

And yet none of those corporations has displaced email, despite the fact that it has become a universal cyberattack channel, with a stagnant UX that doesn't address most real-world use cases for email!

I saw a need for a safer, better, decentralized protocol for email, so I drafted one (TMTP) and implemented client & server. More at:

The primary problem for email at this point is that it's a highly effective cyberattack channel, because it allows anyone, claiming any identity, to send you any content, without limits. This cannot be "fixed" as it's the intended function.

No one was working on an alternative that addresses this problem, so I drafted & implemented "TMTP".

Before ditching SMTP/etc, we'd need something to replace them.

TMTP (my work) is a candidate. More at https://mnmnotmail.org/

Well here's TMTP, a new email protocol, which uses a mix of text (JSON) for headers and binary for attachments.
