I've narrowed this down to the "Thread-Index" header that outlook is  
sending in the ActiveSync forward command. It is too long to be sent  
without the SMTP Binary extension, which not many smtp servers  
actually support out of the box (including Postfix).

Looking into how we can intercept this and possibly mitigate.
