By default, Postfix adds a Received header — on all mail that you send — that lists the IP of the device you sent the mail from. This feature is great if you're a mail provider and you need to debug why one user is having sending issues. This feature is not so great if you run your own mail server and you don't want every recipient of every email you send to know the device and IP you sent the email from. To limit this filtering to outgoing mail only, we apply the filters just to the submission port. See these guides [1] [2] for more context. I have taken care to make the configuration logic be **idempotent**. Unfortunately, due to the syntax of `master.cf`, this requires a small amount of `sed` and `perl` wizardry :( In addition to filtering the Received header, the `submission_header_checks` file is currently configured to filter other, privacy-sensitive headers. If people object, we can remove those filters. The important thing is that the IP be filtered or masked.
