We've been migrating an Exchange infrastructure to Zimbra and now want to move our distribution lists, several of which have many 1000s of users.

However according to the administrator guides, 1000 is the maximum number of recipients that a distribution list can contain. It seems this would cause problems for a lot of organizations. How do you handle lists with over 1000 users?

Our version: 6.0.6_GA_2330.RHEL5_64
