- jwilk 4y agoQuoting CR and LF is no longer allowed in RFC 2822.
- jwilk 4y agoCorrection: it's still allowed, only considered obsolete. :-/
- derefr 4y agoWhich is to say, nobody of note is still allowing it; you can allow it if you like, for anyone who is still doing it; but if you don't, and someone sends you a message, and it bounces, then, well, they already know why.
