True story #selfhosting

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".

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

I lost some #emails due to a problem with #Spamhaus and #Hetzner during the last few days.
So anyone running a #mailserver using those providers should better have a look at this and check their logs/configuration: https://www.spamhaus.org/resource-hub/email-security/query-the-legacy-dnsbls-via-hetzner/

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.

https://gitlab.com/moasda/postfix-docker

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...

I'm helping a friend with his mail server, and thinking of hosting my own again. Has anyone tried #mox #mailserver? https://www.xmox.nl looks made for the demographic (like me) who gave up on running their own, but understand that a protocol only stays distributed when enough parties run it.

Anyone experienced overly false positives after reducing to "reject = 12" (default 15) on rspamd?
(Shouldn't happen, according to rspamd-history)
