Re: Adding custom mail headers via a filter?

So the claim is that if my filter echos a new message to stdout that procmail will take that as the message?

I suggest you check out the "sandbox" testing method. You could easily answer your own question by writing a simple filter and throwing a test message at it and confirming what it does.

The h and b (lower case) flags define what gets thrown at the filter (default is both), so you can rewrite headers, or you can rewrite the body. Rewriting could be as simple as tacking on a footer, or truncating the body to just a few lines (say you're processing bounce messages and don't want to receive bounced attachments).

In practice, a procmail filter recipe isn't any different than a pipe at the shell.
