Same problem with kmail 1.9.6. Selected not supported login method (e.g. CRAM-MD5 instead of Simple Text) then password dialog cannot be cancelled. After restarting (with checking mail on start enabled) it is even difficult to reach the relevant setting then when the password dialog cannot be cancelled.

Exactly the same problem for me, when not connecting via TLS (because the server is configured to reject unless a secure session is being used).

Sequence of events:

1) ask for password 
2) say that LOGIN is disabled 
3) goto 1

I'll probably fix it by editing the configuration manually, but this is a major pain :)

The problem is still present in the latest KDE released with OpenSuSE 10.2, KMail 1.9.5.

But it just shows up if you type your password for the first time.  If you cancel on the dialog box before the kamil window opens, then it will be possible to make the changes.

This is a real bug and a real PITA when a user gets this problem.

If the problem is based on wrong credentials, this might help.

My problem was a server that switched the authentication mechanism. KMail did not allow me to open the configuration dialog and change the settings due to this bug.

That was the same case here.  The server changed from using TLS to using SSL on the right port (IMAPS).

Created attachment 20116 [details]
proposed patch part 1, allow cancel

Created attachment 20117 [details]
patch 2, don't ask for password due to missing SSL/TLS

Allow the user to cancel kmail connection attempts when the account
settings are incorrect (Novell bug 247903).
