Comment (by Nick Orr):
RFC 2822:
> Each line of characters MUST be no more than 998 characters, and SHOULD
be no more than 78 characters
Instead of Django being ok with feeding an underlying Python library data
that will cause an exception as with all things Python it seems like
Django would be better off getting out of the way and letting the users
shoot themselves in the foot.
I'd suggest that this call:
nm = Header(nm, encoding).encode()
Include the actual RFC line length limit of 998 in either the class
instantiation or the encode method as either of those accept maxlinelen as
a kwarg.
Or as a non-changing compromise it could be hived off into setting with
the default being 75 as it stands now. That would allow developers to
overwrite the setting if needed. Though it would also add yet another
setting for people to know about.
Either way the current implementation is likely to cause a great deal of
pain as developers find out that an email addressed to: "Django with a
really long name for reasons that make sense in the context of a project
<[email protected]>" are inexplicably crashing in core Python code
they've never seen before.
Most of us would rather send a wonky, if technically correct, email versus
just having that email vanish into the ether.
