99% of the time everything is perfect, it is only the three users in the one office that get this error, it is of course the head office for the customer and so they are very upset, because they get timeout errors on their email clients.
They are using different versions of outlook, and outlook express, I have deactivated all nortons email scanning etc
Did you figure out anything? Enabling rawlog (http://dovecot.org/bugreport.html) for those users and looking at them might show if the mails contain something special that causes the client (or Dovecot) to break.
