Version: (using KDE KDE 3.5.6) Installed from: Ubuntu Packages OS: Linux I have experienced quite some trouble trying to send messages via SMTP/TLS on almost all T-Mobile wireless networks at train stations all across Germany. Since the following error dialog says I should file a bug report and since I can't quite believe that one of the leading Wireless providers does not support a common protocol, here is the bug report. The message below (in German) says that sending has failed because the TLS protocol is not supported. I should deactivate TLS in case I do want to send messages (unencrypted). In the end, it asks if it should continue sending the messages. This is the full dialog in German: ***cut*** Das Versenden ist fehlgeschlagen: Interner Fehler Bitte senden Sie einen ausführlichen Problembericht an http://bugs.kde.org Ihr SMTP-Server unterstützt das TLS-Protokoll nicht. Deaktivieren Sie TLS im Kontrollzentrum, falls Sie eine unverschlüsselte Verbindung aufbauen möchten (Persönliche Einstellungen -> Verschlüsselung). Die Nachricht verbleibt im Postausgang, bis Sie entweder das Problem beseitigt haben (z. B. falsche Adresse) oder die Nachricht aus dem Postausgang entfernen. Das folgende Transportprotokoll wurde benutzt: ... Soll mit dem Versenden der verbleibenden Nachrichten fortgefahren werden? ***cut*** I have three profiles on my system, all for web.de e-mail accounts. They all deliver to smtp.web.de, port 25. Retrieving messages (via pop3/ssl) works flawlessly on all networks I have been on so far. I do not have any problem with my current settings on most wireless notworks and my cable access at home. So, what should I supply in order to help solve what seems to be a kmail bug?

I have just checked back with T-Mobile. The non-functional SMTP protocol is intentional. Deutsche Bahn, who technically operates the Hotspots, does not want users to send e-mails via SMTP...
