I don't know about Outlook Express, but I was unable to get Outlook
2007 to use login credentials, and my dovecot is configured to support
NTLM, SPNEGO and GSSAPI :(

Thunderbird on Windows will use the login credentials if dovecot
supports GSSAPI and has the proper kerberos setup. Check use secure
authentication or somesuch.
