As this was happening to me more and more (people "on" some variant of googlemail, or hotmail/outlook/some other Microsoft mail thingy, etc. not receiving my mails -- and digging further yes, receiving them in their spam folders and thus not seeing them), I bit the bullet and went for SPF/DKIM (I hadn't the guts for DMARC yet, I don't particularly like that one). I think bigcorps love that, because they hate the decentralized nature of mail. Spam pressure plus measures making the live of small mail providers help centralization. And this spam folder thingy was too tasty to pass on: SMTP RFCs force you to either deliver a mail or bounce it [3]. Since bouncing has become unattractive (cf. backscatter spam), the temptation to silently drop things was high, but not permitted by RFC. Ha! Deliver to a spam folder and tell the users that it is EXTREMELY DANGEROUS to "open" a spam mail, heck, it's even dangerous to sneeze in the general direction of your spam folder [4] -- Tada! "no, we don't drop any mail, missus, we deliver it. It's the user who's doing that". This is what I call Emergent Evil. I thon't think there's a single person out there scheming out those things, but a corporation as a whole does come up with that kind of perverse behaviour. Of course, most of the spam I receive these days (i do look into my spam from time to time :-) has correct SPF and DKIM records :-/ Cheers [1] https://en.wikipedia.org/wiki/Sender_Policy_Framework [2] https://en.wikipedia.org/wiki/DKIM [3] There's also reject at the DATA phase, which is quite attractive for smaller sites.
