I often miss stuff but near as I can tell this would be a bad thing. Joe
Job/backscatter wise.

Zombie soliders 1-n send email on behalf of joe at job.com to list-
L at lists.foo.org.

Worst case, list-L sends N subscribe challenges to joe.

Likely case, Joe gets a (1) challenge and clicks "this is spam", thefore
making it harder for nancy at job.com to get her list emails.

Best case, Joe gets (1) subscribe challenge and ignores it.
