New submission from Anton Khirnov <an...@khirnov.net>:
When parsing a (broken) mail from linux-me...@vger.kernel.org (message-id
20190212181908.horde.peighvv2khy9ekuy8ta8...@webmail.your-server.de, headers
attached) with email.policy.SMTP, I get an AttributeError on trying to read the
'to' header:
/usr/lib/python3.7/email/headerregistry.py in <listcomp>(.0)
345 mb.local_part or '',
346 mb.domain or '')
--> 347 for mb in addr.all_mailboxes]))
348 defects = list(address_list.all_defects)
349 else:
AttributeError: 'Group' object has no attribute 'local_part'
The header in question is:
To: unlisted-recipients:; (no To-header on input)
The problem seems to be that mb is a Group and not an Address, gets token_type
of 'invalid-mailbox', but does not have the attributes local_part/domain that
are expected in mailboxes. Copying the line
local_part = domain = route = addr_spec = display_name
from InvalidMailbox to Group fixes this, but it is not clear to me this is the
right solution, so not sending a patch.
