31234	Increase entropy for 1.11's make_msgid() randint component	Brad	nobody	"Django 1.11 copies CPython's make_msgid (https://github.com/django/django/blob/stable/1.11.x/django/core/mail/message.py)

However, it is missing a recent change that increases the number of bits used in the random integer part of the identifier to avoid a hash collision.

Ref:

- https://bugs.python.org/issue6598
- https://github.com/python/cpython/commit/ae760c0a2ccd5557bfd915c947dfbcd3ed64fd60#diff-9150fb3cb06040b8e09b07aeae5de8c3
- https://hg.python.org/cpython/rev/933addbc7041

The 1.11 implementation of make_msgid() could be updated to reflect this upstream change.

Note that this does not affect Django 2.x or 3.x because they use email.utils directly."	Bug	closed	Core (Mail)	1.11	Normal	wontfix			Unreviewed	0	0	0	0	0	0
