* Unlimited Send/Receive Accounts
You can configure and use many accounts with InScribe as opposed to the just one with i.Scribe. This allows you to receive mail from many sources and access groupware features like shared calendaring.
* Unlimited Filtering
A simple filtering system can decide a course of action when mail is received. From moving it to another folder, deleting it, printing it out or auto-reply to it.
* Multiple Identities
Each account allows you to use a unique identity to send and respond to mail with. When replying, InScribe automatically uses the identity associated with the account that the email was received through. So it's easy to keep your different roles separate.
* Outlook (MAPI) Export
Replicate some or all of your email to an Outlook MAPI mail store. Great for users on the road that want to sync all there mail received on the road to their desktop running Outlook.
