Description

When e-mail messages are created with enabled_smart_spoofing disabled,
the 'From' header should match a DMARC failure but instead the original
from_address is used.

This changes makes e-mail messages copy the same functionality as DMARC
not allowing spoofing when enable_smart_spoofing is disabled. This
changes the mail tests to expect the change in functionality when
enable_smart_spoofing is False.

This change is from the comments on the review for adding an option for
disabling e-mail smart spoofing (https://reviews.reviewboard.org/r/9209).

Testing Done

The full testing suite for djblets was run.

I've added a test case for having enable_smart_spoofing=False. As for regressing functionality, that all depends on what the expected behaviour is for when enable_smart_spoofing is set to False.

The comments for all this logic no longer match the conditional, making it harder to understand the impact of the change in behavior.

bleblan2 Oct. 18, 2017, 6:20 p.m.

Moving the check for enable_smart_spoofing was done to match the expected functionality I understood from your comment https://reviews.reviewboard.org/r/9209/#comment39603. Without this, passing in enable_smart_spoofing as False doesn't send the email as a <Name> via <service> but instead skips over the code at line 187 where build_email_address_via_service is called to avoid spoofing and sends with the original sender and from_email that were passed in.
