Yes.

No, and no.

action_tempfail halts delivery of the message and issues an error code to 
the sending system.  It's just like action_bounce, except that the error 
code indicates the problem is temporary (overloaded server, down for 
maintenance, greylisting, whatever) instead of permanent (blacklisted 
sender, unknown user, etc.).

Remember, any time you call return, it'll stop processing the 
subroutine.  So in this case, it will *never* call delete_recipient, and it 
will only run up to the first recipient that triggers should_greylist().
