I'm attaching the patch I just sent upstream in rt.cpan.org #21276.
Note that this supersedes debian/patches/01_fix-race-on-bad-rcpts.patch
and also fixes #412041, so the old patch should be removed.

I won't upload a patched package right away: this is a rather substantial
change, and I'd prefer to get it integrated upstream.  Let's wait a
while for them to respond first.
