I’ve suspended @xyzsco for one month for their response to @alento. Personal attacks violate our code of conduct.
@alento Your initial reply could have been phrased better. The imperative form (“Do…”) can be understood as aggressive and dismissive. And while MIME is the right standard, it’s not likely to be very helpful for someone as a first starting point to simply decode the email body. I would have said that there is no encryption in the message, it is simply encoded in the usual MIME format, and per the Content-Transfer-Encoding it is simply base64 encoded, which any number of tools can un-decode.
I am also deleting the body of the message because it’s easily decoded and the poster may not have known that.
