Hm, okay, that does sound like the real client IP will get lost and every connection will appear to come from the proxy then. It would be good if that were passed somehow. My current setup adds the X-Forwarded-For header for example.

Oh interesting, I’ll have to look into that. Is this with that “proxy protocol” I’ve seen mentioned? If not, does this preserve it pass through the client socket address?

Tbf, technically data is still decrypted at the reverse proxy and then re-encrypted. So if someone manages to reconfigure the proxy or read its memory somehow they could read traffic in plain text.

However then since they have to control the VPS, they could also get a new cert for that domain (at least the way I’ve configured it) even if it was passed as is to the real host via a tunnel and read the plaintext data that way, so I don’t think a tunnel protects against anything.

If someone manages to get root (!) access on this VPS it’s over either way.

Yes, you can just use a reverse proxy for IPv4 only and point it to the IPv6 upstream. That is what I do, with a separate DNS record which then combines the two. See the DNS records for id.knifepoint.net (CNAME), http.vineta.knifepoint.net (AAAA, A) and vineta.knifepoint.net (AAAA).

The reverse proxy config and certificate management is set up with NixOS, if it helps: https://git.dblsaiko.net/systems/tree/nixos/defaults/v4proxy.nix https://git.dblsaiko.net/systems/tree/nixos/modules/sys2x/v4proxy.nix

Two different rDNS names, for stuff that uses it. For example if you want to run mail and an IRC bouncer under different domain names.

Yup, anything you can come up with will only work as well as putting “Delete after reading.” in the mail. You have to trust the recipient.

Tbh I haven’t had too many problems with Postfix – however it is certainly a footgun and it would be nice to have fewer parts to connect together, and better defaults. I might try it out, it looks interesting.

From its web page it sounds like it is both a MTA and MDA, has a built-in spam filter, plus has calendar, contacts and file storage. Do you know how it compares to my current setup of Postfix, Dovecot, and rspamd (and Nextcloud for the others)?

It sounds like you need a split DNS setup. systemd-resolved can do this for example. As soon as you need any sort of slightly more complex DNS setup using just resolv.conf isn’t going to cut it.

Element/Matrix does calls and screen share also by the way!

(Teamspeak can do screen share? That’s news to me!)

Ah okay, so you know some behind the scenes info or at least more than just this. My bad, but tbh you should have lead with that because initially I thought you completely misread what the text was saying because I pretty clearly read the queer mentions as “this is not just transphobic attacks by bigots” (see my other comment). Sorry!

There isn’t really, you can probably use sendmail as well. Postfix is just the MTA I’m used to and know can do all of this.

From what I’ve heard about sendmail’s config file, I personally wouldn’t want to use it specifically though…

Yeah, this should work (assuming by email client you mean MTA).

Alternatively, you can set up Postfix to deliver mail over SSH to another MTA by defining a new service in master.cf that calls sendmail on the destination server. This postfix could run in a container as well or on the host, whatever is reachable.

Old NixOS configuration for that here, see the default_transport and masterConfig parts: https://git.dblsaiko.net/systems/tree/modules/sys2x/mail/relay.nix?h=ssh-mail

Alternatively, if you don’t have another mail server somewhere that you want to relay to, the simplest option is probably to just have Postfix deliver into a local mailbox and access that over IMAP (the imaps port should not be blocked, right? You can use a non-standard port though). Turn off non-local delivery though.

I didn’t say that. I would say it makes it much less likely though especially for someone who is openly trans and given someone who has text like “trans rights are human rights” on her web page. Of course it’s not impossible, but it would certainly be hypocritical and goes contrary to the vibe I’m getting from her.

You’re the first one who brought this up. Where is the context for what you are talking about? Which people are saying she’s a bigot?

People I trust who know a lot about community organizing or whatever you want to call this, and are more involved in Matrix than me, told me that this conflict is a lot more complex than just what this document describes.

So I suppose, don’t draw any conclusions just yet if this is the first time you’re hearing about this like it is for me.

Did we read the same text file? I’m seeing none of what you’re talking about. The person who wrote this is also trans.

It’s noteworthy because this is usually the type of attacks a trans person gets from transphobic trolls and not from her own community. Drives the point home that this is not exclusively transphobia.
