Bug 123239

Version:            (using KDE KDE 3.5.1)
Installed from:    Compiled From Sources
Compiler:          gcc 3.4.5 
OS:                Linux

When attempting to send through an exim SMTP server which supports NTLM and requires AUTH, I get the following error:

Sending failed:
Authorization failed, An error occured during authentication: SASL(-5): bad protocol / cancel: server didn't issue valid NTLM challenge authentication not supported
The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder.

I have just tested the account in Outlook and Outlook Express with their respective SPA checkboxes ticked.  They both work fine.  From the Exim debug log, it appears that Kmail simply gives up midway through:

That's where the log stops, and I get the error in KMail.  I can create a testing account if you need one.
