What I find more puzzling is:
  dann@dansdesk.co.uk   jordean@powerpolitics.com       malewa@maleasmith.com
  dan@dansdesk.co.uk    jordan@powerpolitics.com        malea@maleasmith.com

Did you notice that the usernames are different for the CRAM-MD5 login
that fails and the PLAIN login that is successful?
