After several years of building and supporting mail processing tools for Postfix, we are introducing a solution dedicated to Zimbra Collaboration Suite. MSH Zimbra Rules 1.0 is the first release of a new generation of the product, rebuilt from the ground up on the experience we gained with MSH Postfix Milter and the thousands of messages it processes every day.

Signatures and personalized messages are only as good as the data behind them. If job titles, phone numbers and department names are entered by hand, someone forgets to update them after every reorg, promotion or new hire, and the signatures going out the door quietly drift out of date.

A disclaimer rule that skips a message, an attachment that should have been stripped but was not, a sender who insists their email never arrived, complaints like these usually land on your desk hours after the message already left the server. Reproducing the conditions in a test tool only gets you a guess at what happened, not a record of it.
