After jumping through several hoops, I got my Proxmox mail gateway working!

- Do **not**, I repeat, **do not** use incus config device add $contname $devname proxy *without* nat -- everything will be passed to the container as 127.0.0.1 - PMG will act as open relay!!!
- PMG uses the search domain in /etc/resolv.conf as "domainname"
- PMG uses the hostname in /etc/hostname as hostname
- you need both for the FQDN!
- Set up `ufw route allow proto tcp to $containerip port 25`
- Set up static IPs, for the container, otherwise incus will refuse to add the proxy with nat:
* incus config device set prox-mail eth0 ipv6.address=fc00::25 security.ipv6_filtering=true
* incus config device override prox-mail eth0 ipv4.address=10.0.0.2
* within the container, setup the static ipv6, if applicable
- Add the proxy device with NAT
* incus config device add prox-mail public6-port25 proxy listen="tcp:[host-public-ipv6]:25" connect="tcp:[fc00::25]:25" nat=true
* incus config device add prox-mail public-port25 proxy listen="tcp:host-public-ipv4:25" connect=tcp:10.0.0.2:25 nat=true

Tbh, ich fürchte etwas, dass embassy eventuell a) overkill ist oder b) ich damit in eine Sackgasse komme wenn das mal nicht weiter maintained wird.

Bei vendor sdks in C weiß man wenigstens einigermaßen, woran man ist?

I want to have more money so I can primarily save more money, so I can feel more safe, and maybe work less, to have more time to do things I like?

Ich hab mit Embassy rumgespielt und ein paar LEDs auf nem NRF52 zum leuchten gebracht. Mit Rust.
Joar. Ist schon nice.

Eigentlich keine Lust auf Fitti... Aber muss ja

What's the co2 content in the office....?

#Developers of Mastodon, I'm curious what kind of software you work on in a *paid* capacity. Please share for reach x

Was will man eigentlich als hardware-token für ssh-auth benutzen? Habs mit yubikey versucht, aber das ist irgendwie goldener analkrebs, weil verwaltung und benutzung broken sind... irgendwelche tipps?

I still don't get whether I need SRS for my setup

(External -> my VPS with PMG -> mailbox.org)

Or not...

Got a book "how to stop procrastinating" from the library.

It's been sitting on my desk for two months...

*seufz* Sonntag Zug gebucht, heute fällt mir auf, dass an der Pinnwand noch zwei Gutscheine aus einer Erstattung hängen -.-

I ****hate**** spending money.
Mostly because I so often bought the "wrong" thing and then couldn't return it, and only resell it with >50% loss.
I'd rather not buy anything at all then

My #DwarfFortress character sheet would say

Unmet need: fursuit hugs/cuddles
Unmet need: craft something
Unmet need: satisfying work
Unmet need: make merry

Okay, gonna try detergent for wool stuff without pafume, I think?

... *runs PMG on netcup VPS*
... Why does mail relaying not work?
... Outgoing connections to port 25 (e.g. mailbox) don't work...
.... oh wait. Default block actions by providers.
