Lot of companies want to force enable read receipt so that all the emails will ask for Read Receipts and get confirmation. At the same time, it also becomes annoying if employees have to manually "Accept" read receipt every time they read an email.
This Zimlet marries the best of both worlds. It enables "Ask for Read Receipt (of emails I send)" and it also enables "Automatically Accept Read Receipt Request (for emails I receive)" options of Zimbra. So companies can now enforce the policy w/o annoying employees.
