Welp, since yesterday's post asking questions about using OpenDMARC with Postfix got, basically, crickets, I am led to the conclusion: nobody uses OpenDMARC with Postfix.

So let me ask instead:

• Is your Postfix configured to reject mail from outsiders pretending to be you?
• Is your Postfix configured to reject messages that fail DMARC?
• If so how?
