Add disclaimers to outgoing emails

Adding a legal disclaimer to outbound email is easier than you think. You only need Postfix, the MSH Postfix Milter application and a few minutes to set it up. The goal is simple: append the disclaimer to mail that leaves your organization, while internal and inbound messages stay clean.

The usual problem with plain Postfix content filters is that they apply the disclaimer to everything, inbound, internal and outbound alike. Working around that means maintaining lists of sender addresses and keeping them up to date whenever staff changes. MSH Postfix Milter understands message direction directly, so you do not have to approximate “outgoing” by matching sender addresses.

Disclaimers that only touch outgoing mail

The application works as an external standalone milter that integrates with Postfix through the official and standardized Milter API. Rules can combine many conditions and exceptions so you can decide exactly which messages get a disclaimer and which do not. Because direction is detected at the server, internal and inbound mail is never modified, and you avoid duplicate disclaimers on replies.
