Episode 032: “Reading an Email Header”

Florian and Anthony start the new season – in this episode, we’re talking about what an email source looks like. We’re mainly looking into the most important elements of email headers, but also have a look into plain text and HTML MIME parts and Base64 encoding.

We’re looking into a few good and bad examples and try to avoid the Corona-topic as much as possible.

Have fun with this episode:
