#google bekommt sein Mailinglist-Spam-Problem nicht in den Griff. Spammer erzeugen eine durch Googlemail gehandlete Domain, generieren dahinter eine Mailinglist und versenden darüber Spam. Ergebnis: Alle Auto-Replies landen bei allen "Beglückten".

Da ich keine Google-Mailinglists abonniert habe: Alle Mails mit einer "X-Google-Group-Id" landen jetzt direkt im Müll.

#mailserver whoes

Dinge um die ich als IT Entscheidender einen großen Bogen mache:

- #broadcom
- #hp
- #lenovo
- #lancom
- Eigene #mailserver
- Telefonanlagen-Dienstleister
- proprietäre Security (Firewall, SIEM, etc.)
- Windows (sofern Möglich)
- #office365 (oder wie auch immer das diese Woche heißt)
- #sap
- Datenverarbeitung auf Android
- Port Forwards
- #docker
- Cloud/SaaS Dienste
- Tageslicht
- GData, Symantec etc.
- GoDaddy und Co.
- Zertifikate zum Kauf #letsencrypt

Wie sieht eure Liste so aus?

This weekend's project:
Replaced my #Postfix #MTA #mailserver with a new one. I had been running a #Ubuntu based one since 2020, and it didn't deal well with an in-place upgrade.

New machine set up on #Debian 12, with a bunch of tips stolen from @mwl 's book Run Your Own Mail Server and from https://workaround.org/ispmail-bookworm/

Du hast die Chemnitzer #Linux Tage 2025 verpasst? Kein Problem! Ab sofort findest Du die Videoaufzeichnung und die Vortragsfolien der beiden Heinlein-Vorträge auch in unserem Expertise-Blog.

If anyone out there runs a #Plesk server, check to see if your have a ton of emails stuck in your mail queue. There was a problematic email security update that got applied within the past 12 hours that caused mail queues to stop processing both incoming and outgoing email.

Fortunately, it's an easy fix.

Every time I look at #mailbox providers, I get happier about my #Runbox.

I just gave a look at #Migadu, which was heavily recommended in some threads here. In 5 minutes I found 3 things I don't like:

1) No explicit pricing to get more storage space beyond the plan's default.

2) Says servers are "in France" but doesn't say with whom in the #privacy policy.

3) Prohibits "immoral, unethical or socially unacceptable activity".

Configure Postfix MTA for Use with #Mastodon Effortlessly (Effortless 5 Minute Guide) This article describes how to configure Postfix MTA for use with Mastodon server. Admins who self-host their Mastodon instances can easily configure Postfix MTA (possibly even to do so using the same VPS server) to handle the #email services.

So, last night I finally took the last step and switchted my DNS entries to my own self hosted mail server (@mwl your book was really helpful - great work!)

But now I am back to my previous problem - which mail client to use on iOS and macOS - any suggestions fediverse? (boosts are quiet welcome)
#selfhosted #email #mailserver #ios #macos

Maybe I will finally give a try with setting up my own mail server with Mox. It looks very promising!

Finally moved my whole #server to #proxmox. I will have to move my #mailserver too but the overall transition went pretty smooth

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.

Falls hier jemand sonst noch #Mailserver bei #Hetzner betreibt, und DNSBLs von #Spamhaus verwendet: Schaut mal in eure Logs, ob ihr wegen Spamhaus nicht gerade alle Mails ablehnt.

Ich hab das bei mir gerade nur gemerkt, weil mir eine nette Person auf Mastodon geschrieben hat...
