Use fetchmail to retrieve mail from exchange 2010 server

After my employer upgraded to exchange 2010, i could no longer get my mails by fetchmail.

The problem was the gssapi hanging and not falling back to plain authentification.

This can be solved by configuring .fetchmailrc to use plaintext authentication

poll server.domain.tld
  protocol imap
  auth     password
  username "vorname.nachname"
  password "secret"
  ssl
