Huh.  I thought I sent an update about this but it vanished in the aether.

I just turned on a new DMARC-aware version of ezmlm-send which rewrites
the From address for any domain that is DMARC sensitive to something like:

"User name via mailinglist <mailinglist AT sourceware DOT org>"

when the mail is broadcast to the mailing list.  I would have done this
sooner but my ezmlm skills were really rusty and I almost ran out of
extremities to shoot.

Please send any errors or issues encountered to overseers AT sourceware DOT org.
