### Notes
* The base_image_uri of the images in forwarded emails would be replaced
with `https://chat.zulip.org/static/images/emails` inorder for the email clients
to render the images. See `zproject/email_backends.py` for more details.
* After changing any HTML email or `email_base.html`, you need to run
`scripts/setup/inline_email_css.py` for the changes to be reflected in the dev
environment. The script generates files like
`scripts/setup/inline_email_css.py` for the changes to be reflected
in the development environment. The script generates files like
`templates/zerver/emails/compiled/<template_prefix>.html`.
* Images won't be displayed in a real email client unless you change
the `base_image_uri` used for emails to a public URL such as
`https://chat.zulip.org/static/images/emails` (image links to
`localhost:9991` aren't allowed by modern email providers). See
`zproject/email_backends.py` for more details.
* While running the backend test suite, we use
`django.core.mail.backends.locmem.EmailBackend` as the email
backend. The `locmem` backend stores messages in a special attribute
