For any high volume email handlers, there’s very little information available at the Edge when it comes to EndOfData. And rejecting after that is catastrophic more often than not.
And yes, it outs your trap to those who bother to look at their logs. Which might only be the occasional email nerd, or spammers.

Not sure I understand this point of view. I think everyone should be rejecting after DATA, if only to stop the abuse of the email address validation services. The thing with spamtraps is that they should not be in your DB in the first place (especially pristine ones) or should have been trimmed from your DB a long time ago (back when they went from a usable user address to a bouncing address before being reactivated as a spamtrap). This is a very limited view and one which fails to account for the realities on the ground. The reality is spamtraps (pristine, recycled, whatever the term du jour is regularly end up on lists because people submit addresses as part of their online existence. Sometimes they give the wrong address. Sometimes that’s on purpose (I want your thing but don’t want mail from you) and sometimes it’s an accident (I don’t know my address or I fat finger something). Some of those wrong addresses have never been used before. Some of those wrong addresses belong to third parties. Some of those wrong addresses used to belong to someone but were abandoned some period of time ago. I don’t know who came up with this whole “pristine” and “recycled” spamtrap thing, but the terminology has not brought any clarity to discussions. laura -- Having an Email Crisis?
