What happens if I don't request an upgrade to 5.0?

There will be a time when PoliteMail will not be able to support anything under version 5.0. We will contact you well before this time expires to schedule an upgrade. 

Some of the security, employee privacy, and authentications will be out of date on older versions. We want to make sure all of our customer's environments are secure, and we want to offer you the best features possible. Many of the persisting issues in the 4.0 PoliteMail series have been resolved in 5.0.
