A couple of years ago I fell out with #gmail and migrated to https://privateemail.com

I've now fallen out with privateemail and decided to selfhost (again).

Now running #postfix, #dovecot, #rspamd and others via docker-mailserver. Had to use #smtp2go for outbound due to relay issues.

Also selfhosting #radicale for calendar/contacts and #immich for photos.

So far so good ... seems faster than I had before plus #opensource. Need to let it bed in a bit and keep an eye out for errors.

Hey zusammen,

ich versuche mich aktuell an einem eigenen Mailserver. Ich möchte nicht einfach eine Copy-Paste-Anleitung umsetzen, daher wage ich mich aktuell erst an einer Minimalkonfiguration, um alles auch nachzuvollziehen.

Die sieht aktuell so aus:

Ich würde mich freuen, wenn ihr mir sagen könntet, was da UNBEDINGT angepasst werden muss, damit das Ding kein Sicherheitsproblem ist. Also keine neuen Funktionen.

Hey #Sysadmin|s of the fediverse, I want to ask you for some recommendation, I want to get rid of my old and molden mailsystem.

I just need Mail for a couple accounts and domains for myself and some friends. Would be nice to have a WebGUI, but is not a must.

For #email configuration and #security check, the European Commission provides a great tool: MECSA https://mecsa.jrc.ec.europa.eu/en/
conclusion: I still have some improvements to implement on my own server
#sysadmin #linux #postfix #DKIM #DMARC #DNSSEC #selfhosting

Woohoo! I finally got email working for darkmoon.social. Emails appear to be flagged as spam, so there's more work to do, but that's a major step forward. And it only took me 2 1/2 years to get it done.

I'm running the mail server locally because I apparently hate myself, and I don't need free time, but at least it doesn't cost any extra money.

Ah, je viens d'avoir le "unexpected attribute smtputf8 from xxx socket (expecting: sendopts)" Voilà ce qui arrive quand on ne lit pas les release notes.
(Executive summary : redémarrez Postfix.)

Well, after a lot of swearing… I *think* I have a Raspberry Pi 400 running #AlpineLinux … tethered to my 4G phone hotspot … acting as a crude WiFi router/bridge for my border router running #OpenBSD which is tunnelling to my OpenBSD VPS at Binary Lane.

Over that tunnel, I now have #Postfix on the home mail server, relaying over the VPN to #OpenSMTPD on the VPS.

Should be useful the day I have to leave Internode… but for now, it's bypassing the rather dead NBN service (thank-you #CycloneAlfred).

Why can't I get a Docker container (using docker-compose) to access Postfix running on the host on port 25?

I must be missing something, obviously

Any takers?

What do I need to send emails on port 587? #email #postfix #smtp

NixSpam DNSBL von Heise / Manitu ist nach einer grace period nicht länger im Service und gibt nun Fehlercodes zurück. Entfernt ix.dnsbl.manitu.net aus euren MTA-Konfigurationen.

#ProxmoxMailGateway 8.2 has been released (#Proxmox / #ProxmoxMG / #MailGateway / #ZFS / #OpenZFS / #SpamAssassin / #Postfix / #PostgreSQL / #Linux / #Debian / #Bookworm / #DebianBookworm) https://proxmox.com/

#fedihelp , please: I'm #selfhosting #dovecot and #postfix and running out of disk space with my mails reaching back into last century. I'd like to remove the oldest ones and keep an archive of any kind on a different host. What would be the easiest way to achieve that?
Maybe just imap-sync to some special maildir?

Edit:typo

Considering to migrate off #Google and other US #bigtech dependencies since they seem to get stuck deep in #Trump|s asshole. What is supposed to be the "gold standard" replacement for self hosting a tiny OSS mail server (own domain, 4 accounts, IMAP + mobile + web client) these days? Long years ago I've used #postfix + #dovecot. Is still still the way to go?

Are you #selfhosting an #email server?

I just published an updated #Docker image for #Postfix 3.10.1, based on #archlinux.

The email server is fully customizable via Docker mounted volumes for usage on a Virtual Private Server (#VPS). Just use the Docker registry provided by the project.
