I think the original was tagged by gmail as spam because it had too many
recipients. It came back with lots of "rejected by recipient", but I think
they just do that to confuse spammers. So likely no one received it.

Great, thanks. I didn't notice because yesterday's build didn't include
the fix, and starting today I dropped the one qemu boot test that reported
it (beaglexm) because that doesn't work anymore for other reasons (due to
commit fb2c599f056, more specifically).
