I mean, it's not *wrong* to do that -- older mail standards required that all MTA-to-MTA communication should be done in 7bit. But we're literally talking previous-century legacy protocols here. Forcefully converting all mail to 7bit is about the most 90s thing you can do these days, short of being really into mullets and Arsenio Hall. > E.g., patches I punched out today via "git send-email" even have the > line continuations thingy again (they disappeared for a while, maybe > there are different MTAs involved and it's like playing the lottery) Those show up when your lines are longer than 76 characters. Because, you know, otherwise the message would be too wide to fit through the ethernet cable. https://en.wikipedia.org/wiki/Quoted-printable#Quoted-Printable_encoding Best regards, -K
