 However, the other issue is to break or remove author domain
 signatures.  John has pointed this out since a long time, for FBL
 reasons.  Doug has brought out the same issue for replaying attacks
 aimed at breaking reputation, because replaying is definitely out of
 control in case of publicly distributed messages.

What's the danger of replaying legitimate mail, other than to cause
volume detection alarms to go off?

If this message were replayed to all mailboxes in the world, the 
number of complaints might be overwhelming; the more successful spam 
reporting, the more scaring this possibility.  And if anyone uses that 
for tracking domain reputation, it might drop below small integer 
ranges.  In such scenario, one may consider it safer to only sign mail 
destined to trusted recipients.
