Hi there,
our ZCS 5 will expire soon. Because of a switch to a newer Mail Serversystem we asked us what will happen to the ZCS5 when the license expires?
I found a thread where this was discussed a time ago about ZCS6/7 but i didn't find information about the ZCS5 which was provided by yahoo at its time.

Is it the fact for the ZCS5 too, that it will run 30 days after expiration as before and then will fall back to Open Source version (without possibility of adding new postboxes etc. until upgraded to fully Open Source system)?
