[Dovecot] Enable outlook-idle workaround.

I just recently discovered dovecot. I am evaluating the program and several clients uses Outlook/Outlook Express.

In the clients issues section of dovecot.org is says "You should enable outlook-idle workaround"

Ok, maybe I am missing something very obvious here but I can not find any documentation on how to implement the outlook-idle workaround. Can anyone point me to an article or something with more details on this issue?

Thanks in advance.
