I've tried googling a little, but I don't know enough to figure out what my query should be.
I notice that every time I set up mailgun or mandrill or whatever I always have to set up domainkeys. That part makes sense - RSA, public/private, etc - I get that. Intuitively I would think there is a single standard for where to find SMTP domain keys, say smtp._domainkey.example.com But instead it seems like one of these prefixes get picked at random: k1._domainkey.example.com mx._domainkey.example.com pic._domainkey.example.com (this one baffles me) mailo._domainkey.example.com So I'm looking at my long list of domains and it appears that only those 5 variations occur, but I'm not seeing a pattern. Why isn't there just one standard prefix? How does that querying server know which to query? Isn't _ an illegal character? I'd love to be pointed to some reading material as well as some short and sweet explanations if you have one on hand.
