Unsure how to issue a "PR" (Problem Report?) with a test case.
Here is my best effort:
Create a file "email.eml" in the current directory, as attached.
(The contents were lifted from RFC2822 section A.1.3, but I deleted the ";" at
the end of the "To" header. The file has CRLF line endings.)
Then run the following test program (It appears that I can only attach one file
to this ).
$ cat test-bug.py
from email.policy import default
import email
with open('email.eml', 'rb') as f:
msg = email.message_from_binary_file(f, policy=default)
toheader = msg['To']
for addr in toheader.addresses:
print(addr)
#----------------------------------------------------
# Output without the fix:
$ python3.6.5 test-bug.py
Traceback (most recent call last):
