@TenFour, antispam is a group of complicated policy, not the single accident can influence the final result. for example, new domain can get a small bad score, greylist, RBL, sender reputation, SPF, DKIM, etc,all those could make message increase spam scores. But the total score would or would not trigger spam judgment, it depends.

I once worked as the antispam team leader in a large ESP, who has 400+ million users. antispam was very challenged job to me.
