I really think KMail2 is hating me. I upgraded form KMail 1.x (KDE 4.6.5) to KMail2 (KDE 4.7.0) and now, I can't send mails.

Everytime I try to send a mail, I get the following message:
"Fehler beim Übertragen der Nachricht. Der Prozess für das Protokoll smtp://xxx.yyy.net wurde unerwartet beendet."
Not sure about the English translation, but should be something like this:
"Error while sending message. The process for the protocol smtp://xxx.yyy.net terminated unexpectatly."

.xsession-errors shows the following error:
"kio_smtp(515)/kio (KIOConnection) KIO::Connection::connectToRemote: Unknown requested KIO::Connection protocol=' "" ' ( "" ) "

Thing I tried:
I started with the default migration setup.
I tried restarting Akonadi, Mail dispatcher (with akonadiconsole) and KMail.
Restarting the XServer does not solve the problem either.

I tried deleting/recreating identies in KMail, didn't help either.

Next thing I tried: Clean Akonadi setup:
Stopping Akonadi, deleting everything in .kde4/share/config/akonadi*, .local/share/akonadi, .config/akonadi. (I didn't delete the migration configuration, therefore nothing migrated from old KMail.)
I also deleted the mysql database.

Result: Still the same problem, I can't send emails.

Well, last option: creating a new user. Sending emails with KMail works.

Now, the questions is: Which configuration files do I need to delete, so KMail sends mails from MY account???

UPDATE: I tried different mail transports from smtp and the all work. Seems that the only one that isn't working, is SMTP.

I would suggest to avoid deleting files from akonadi and the like because what could happen ie leaving the database with inconsistent information (since it's stored in other configuration files).

That said, did you enable more debug with "kdebugdialog"? Perhaps enabling debug for the mail dispatcher agent will tell what's going wrong...

I enabled some debug messages (kmail2, kio_smtp, mail dispatcher, ...)

This is the output from .xsession-errors

Does your SMTP server support different authentication mechanism? Did you try using different methods to see if one passes through but not the others?

I even tried different SMTP servers, the problem is always the same. And with a new user, the same configuration works. (But I don't want to loose my hole configuration ...)

When you were looking for configuration files to remove, did you look under ~/.config and ~/.local?

Was my first guess, too.

It works now. I think nepomuk caused the problem, but I'm not 100% sure.

Nepomuk does have some involvement in the email sending procedure, so it definitely could be a potential culprit.
