TTBOMK, full debug log shows "everything". Admin can see all contact and
all messages, if they are not e2ee. I can check with prosody upstream if
there is a debug mode, that is less problematic and still helpful for
our use case. In that case, I suggest, that :debvoip group can only
switch on and off this specific mode. E.g. by something like "touch
/etc/prosody/turn-on-debug && systemctl reload prosody" or whatever.

It was and still is a good idea, to have a ToS document. Maybe we can
re-use a proven one from elsewhere?

gfa did create the files in /srv/prosody/antispam/ and members of
:debvoip can edit them. So I guess, that this issue is solved?

I believe, that we should have nginx on vogler on ports 443 and 80.
It's needed not only for BOSH and HTTP file upload, but it is also a
very good idea to run xmpps (XMPP over direct TLS) on port 443. Last
time in a British train, I only could connect to my private Jabber
server on port 443, but not the Debian server.

I can prepare an Nginx config, NP.

Cheers

PS: I recently sent a git patch on the DSA mailing list improving the
group chat function of our server. If you or somebody else could apply
it, that would be great.
