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.

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.
