Means to handle spam

by Schimon Jehudah

Greetings to one and all. I would want to apologise for posting to this mailing-list, as mailing-lists "general" and "jdev" are closed. I am interested in discussing automated spam, and automated counter measures against that issue. I have created a moderation service (i.e. "bot") software to handle this concern. The interface of that software is of XMPP client, so anyone can operate it from anywhere. I would be glad to be honored by your kind participation. https://git.xmpp-it.net/sch/KaikOut Merry Christmas and a Happy New Year, Schimon

Bind2 question

by Thilo Molitor

Why are the inlined bind2 features inside <feature/> elements rather than using the exact same syntax as when announcing the same features in the stream features element (e.g. <csi xmlns='urn:xmpp:csi:0'/>) For reference: <bind xmlns='urn:xmpp:bind:0'> <inline> <feature var="urn:xmpp:carbons:2" /> <feature var="urn:xmpp:csi:0" /> <feature var="urn:xmpp:sm:3" /> </inline> </bind> -tmolitor

NEW: XEP-0509 (Initial Authentication Pipelining)

by Daniel Gultsch

Version 0.1.0 of XEP-0509 (Initial Authentication Pipelining) has been released. Abstract: This specification defines a protocol for discovering if the SASL2 <authenticate> can be pipelined safely along with the stream open, and if so allows the client to perform this pipelining safely. Changelog: Accepted as Experimental by council vote (dg) URL: https://xmpp.org/extensions/xep-0509.html Note: The information in the XEP list at https://xmpp.org/extensions/ is updated by a separate automated process and may be stale at the time this email is sent.

authorization-identifier versus authorization-identity in SASL2 and BIND2

by Thilo Molitor

Why is XEP-0386 (BIND2) talking about <authorization-identity/> at [1] whereas XEP-0388 (SASL2) is talking about <authorization-identifier/> at [2]? Bot specs use it for exactly the same thing: communicating the bare or full jid (if a bind occured). Why this double-element? XEP-0388 even states > If the Client is now authenticated, the Server sends a <success/> element, which contains an <authorization-identifier/> element containing the negotiated identity - this is a bare JID, unless resource binding has occurred, in which case it is a full JID. So it seems like a perfect fit to communicate the full jid after bind using the SASL2 element, why was this extra BIND2 element added? -tmolitor [1] https://xmpp.org/extensions/xep-0386.html#identifiers [2] https://xmpp.org/extensions/xep-0388.html#success

Should new features utilize different namespaces?

by Schimon Jehudah

Greetings. This is a concern about backward compatibility. Preface ------- Earlier, this evening, after I have sent a series of corrections to messages at the group chat of XSF Discussion, Mr. Guus has mentioned the concern of backward compatibility with clients that do not support message corrections, or reactions and other features that have a visual impact. Wed 10 Dec 2025 06:21:44 PM - Guus: > My client displays a wall of text in this chat room, full of quote > chains, reactions, links, and corrections. > > It's completely unreadable. I'm using a very old client with a basic > interface, but until recently, this was never an issue. > > It's disappointing to see that modern XMPP usage can make my > experience so abysmal - at least in rooms where newer clients are > active (even if _or perhaps because_ they try to implement "backwards > compatibility" features). Wed 10 Dec 2025 06:31:45 PM - lissine: > Check https://logs.xmpp.org/xsf/2025-12-10 to have an idea about the > experience of Guus Concern ------- I was wondering whether some features, which have visual impact on messages, should have XML Namespaces (xmlns). Consideration ------------- This would mean that messages that are marked as "corrected messages" will not be displayed with clients that do not support message correction, due to a namespace which is not recognized by clients that do not support that feature. Kind regards, Schimon
