That's why we need to find someone that is able to share real bits on the issues (who's who). We can't expect a provider to fix a bad habit (or to publicly explain there was a bug) if no one talks about it and people keep buying its services ignoring those issues. If they feed a blocklist like that and I buy a blocklist that is fed that way I'd be very disappointed. If they do that sistematically then they will create a lot of false positives and blocklist users will start complaining.. so I really hope/guess we're talking about a bug. > At one point you could do COI and > mail to folks who’d only opened an email in the past few weeks and still get > on a blocklist because you sent to a spamtrap. This affected real senders > who weren’t spamming. Just to make this more interesting, I think this may have a slighly different "story" that may be "right". 2014: I collect the addr...@example.com email address 2015: the example.com domain expires, is bought by the spamtrap network that starts returning 511 this will become a spamtrap for 365 days. 2017: I decide to send an email to that address for the first time, I hit the spamtrap. Some network doesn't report back your first hit, instead they sometimes make opens/clicks, I don't know if they do that to simulate traffic or for some other reasons.. (hint: I saw clicks/opens from antivirus/antispam cloud providers IP spaces, but I don't know the reasons). 2 weeks later I send a second email only to people that opened in the last month, and addr...@example.com is reported, correctly, as a spamtrap hit. So, it was COI, and I was writing only to openers from the last month, and still I hit a "3 years old repurposed spamtrap". Let's take into consideration that spamtrap network have to do their homework to avoid being identified easily, so if they never do opens/clicks they already put a big flash on them. So I think it is OK for a spamtrap to open/click or even reply to an email, but it is important that the email address has been in a "user unknown" state for at least 1 year (or something similar).
