Version: (using KDE KDE 3.5.6) Installed from: Ubuntu Packages In Systemsettings there should be a third possibility to choose a mail client. This could be to choose between "kmail", "webmail" or "other" possibilities to handle email in KDE. - A small wizzard should help to set the right mail hoster for webmail. There is a good solution that also seems to work in Konqueror as well by Scott Severance. ( http://ubuntuforums.org/showthread.php?t=398974 ) However there should be some kind of guarantee that the system is connected with the net. If a mail would be prepared while being offline it should be possible to rest waiting. - This should be a task for kmail again! I open this whish for "Systemsettings". There is already a discussion for the kmail-people - but it has less to do with kmail but more with kcontrol and systemsettings... See: https://bugs.kde.org/show_bug.cgi?id=89805
I don't think this is really possible. Webmail clients are innumerate and unique. We can't add individual support for every single one, sorry. It's just too enormous a task.
