Keep recipients private with automatic Bcc

Every so often, a message goes out to a group of recipients who should not see each other’s addresses, a customer announcement, an alumni newsletter, a notification sent to an external mailing list. It only takes one sender forgetting to use Bcc for every address on that list to be exposed to everyone else.

MSH Postfix Milter’s move all recipients to Bcc action fixes this automatically. When a rule matches, every address in the To and Cc fields is transferred to Bcc, so recipients are hidden from each other no matter how the message was originally addressed.

Trigger it automatically, not by memory

Pair the action with a condition such as recipient count above a threshold, or messages sent to a specific distribution address, and privacy stops depending on whoever happens to be sending that particular email remembering to do it themselves.
