I need to add this header to all outgoing email on my servers:

X-SMTPAPI: {"category": "Forum Notifications"}

How can I do that? main.cf file?

thanks in advance,

- A PREPEND action in an smtpd_sender/client_restrictions access
map

- A Milter program that prepends a header.

- An external content filter.

The first two are the low-cost options.
