XMPP Service Operators - 2021-05-02

so email has this nice feature that i can change service providor, but this is invisible to people because i always use the same hostname. Is this possible with XMPP?

qrpnxz: Question is whether/how the providers support export/import of your data (such as your contact list including the presence subscriptions).

But yes this is possible.

yeah that's important too, but the DNS thing was my main goal here because w/o that it's really game over

alright good to know

But xmpp is no replacement for email

qrpnxz, yes, the DNS thing is comparable (MX record for email, SRV for XMPP, both independent of your A/AAAA/whatever records for other services).

i want to use a CNAME record rather than a SRV record, will nodes use that?

oh i think not

qrpnxz, yes, in that case you can't host things such as web sites elsewhere though (and what's wrong with SRV records?). Anyhow those things are details which make more sense to discuss with a concrete hosting provider.

where i am hosting my domain name much easier to change cname records, but those will not do what i want, SRV it is :)

Talking about account portability: does it make any sense to propose import/export to users as no user can _easily_ register to any public server with its own Domain Name?

(easy means _no asking the admin to modify server configuration_)

I don't think anything is required of the service provider for you to use your own domain name. As for data portability, I think it's a moral obligation of the service to allow you to import/export your data.

croax: why have a own domainname? Why not a own topleveldomain?

:|

There are a bunch of companies who can register "new toplevel domains"

I wait for "*.xmpp" :)))

Yeah I mean import/export is nothing without public servers allowing to register with custom domain names. For a given user he could not transparently migrate from one service to another one, because he's bound to the initial domain name.

No. There are a lot of xmpp providres who host your domain.

You just have to point the dns record to the server or delegate the dns server of the xmpp provider.

croax: you mean https://snikket.org/blog/dapsi-fund-account-portability/ ?

Licaon_Kter: yes. I mean if data migration is achieved but _most of users_ (including ones who don't own domain name) can't escape initial provider because of network pointers (in original URI), is it achieving initial portability goals? christian: I would be surprised in that case, especially when it comes to generate X509 certificates of customs domains.

I've pinged Wojtek ✏

pep., cluxia.eu above ^^^

croax, be more clear what surprises you? hostings domains or certbot?

christian: example: ratio of public servers accepting in-band registration and custom domain without asking the admin to update the conf. ✏

why would the admin have to update the conf

for money?

> why would the admin have to update the conf Allow registration + certs ?

the same reason why the baker delivers bread to him

christian: I assume it was a technical question more than a motivation one ;-)

technical it is no problem

Maybe I didn't understand the right way, but if you own a domain and point it to to rented mailserver and wish to change your mailproviser, what do you change ? Your mails will hopfully stored on your client, because your MX-Record will point to the new server and your old provider wouldn't configure your newone. There should be no difference to xmpp. If you own your domain, you could point your SRV-Record to an other server

> Allow registration + certs ? question mark indeed

> but if you own a domain and point it to to rented mailserver and wish to change your mailproviser, what do you change ? You change the DNS records.

Right, and what will you modify if you change your xmpp-provider ? You will change your DNS-entry

I'm just commenting on Snikket article: > Over the years we have seen many XMPP providers come and go, and when a provider decides to shut down, it’s too often not easy for people to obtain their data and move it elsewhere Most users don't own their domain and access to register an account on public server with a custom domain is not easy. What I am saying is that bringing import/export features won't magically save such users.

MX-record is a "subset" of DNS, also SRV is a "subset"

ernst.on.tour, for the example email , if you own a domain, and you have a dns hosting all you have to poit the mx record to the mail server domain "mx.provider.com". this is all, very similar is it also with SVR records to make a xmpp domain hosting. you must make a SVR record and poit to the server who hosts you

it is a bit more complicated, but nut much :))

croax, normally your data should not be on a server.

Sorry, maybe speaking of two different targetgroups. If your mother got an email-account it will be at gmx.net or telecom.com or ... If she leave that provider, she also lost her email-address. If your technical-affin brother got an email-address he maybe own his maildomain and got a pointer to a rent mailserver. If he will change, he has to modify. His mails have to be stored in his client, otherwise they will dropped

christian: *I* know 😉 But croax seems to want to change his provider without modify the MX because he didn't own the maildomain, as I understand right. s/mail/xmpp/g;s/MX/SRV/g

ernst.on.tour: Exactly. Saying only few people that took care of using their domain and finding a server accepting it is addressed by this portability. Maybe considering a host domain on URI is not enough abstraction

ah, wrong channel ✏

jonas’: thanks

mimi89999 also

What failed?

cert renewal, nothing exceptional :)
