[SAtalk] From xxx@yyy.zzz header added

[Craig Hughes]

As part of implementing CHECK yesterday, I updated my systemwide SA installation and just noticed this morning that mail delivery broke.  It seems SA started adding 'From ' lines to the tops of all messages it processes, which causes my delivery agent to fall over.  I've temporarily fixed this on my end by having procmail run a 'tail +2' after spamc, but I think it's a problem in NoMailAudit.pm -- is there a reason SA's adding this header if there isn't already one there?
