With SPF the rejection happens before the DATA phase and therefore no bounce
message will be created by the receiving MTA. Rather the receiving MTA
immediatey rejects the message saying for example "550 Please submit you
mail through smtp.example.ru". The sending MTA will then send a delivery
failure message that includes above string to the sender.
Now assume that all users of example.ru are Russian speaking and do not
understand any English. Of course in this case the sending MTA creates a
delivery failure message in Russian and publishes the 'exp' string in
Russian: "пожалуйста представьте вас почта через smtp.example.ru". How
should the receiving MTA encode this message in a "55x" SMTP reply? Should
it reply following?
