Thanks for the reply.
Are you aware of any Postfix implementations?
Postfix implements SPF SRS DKIM DomainKeys SenderID BATV and so on
exclusively via plugins. Just like Postfix implements deep content
inspection.
I don't bake my own bread, and I don't make my own shoes or clothes.
Instead, I get them from people who specialize in doing such things.
This is how society has been making progress for thousands of years.
I expect that this approach is also good for the Internet.

Hi Folks,
As many of you will probably know, SPF breaks forwarding using aliases.
The solution is to re-write the from-evenlope when forwarding email.
Does anyone know how to do this with postfix?
With an external MILTER program (Postfix>= 2.6):

Or with an external content filter (Postfix>= 1.0):

Yes, I understand that we have to use Milters and/or external plugins
made by other people. I just can't find any that show me how to make it
work with Postfix.
