The most recent message didn't have rewriting applied. I assume that gmail.com has strict DMARC policies and would ordinarily trigger rewriting. However, I don't see this happening on other sourceware.org lists, either. Maybe we'd need a test posting from google.com.

I am doing so hereby. I haven't got any more of these failed-to-deliver messages since: libc-help-help | Inbox, To Jason | ezmlm warning - .1 DMARC policy. Please contact the administrator of google.com domain 550-5.7.1 if this was a legitimate mail.
