If the attached email file is attached to an email, such as the code
snipped below, the sending will fail due to the presence of non-ASCII
content in the attachment.
{{{#!python
email = EmailMessage(
subject="subject",
body="body",
to="[email protected]",
)
email.attach_file(original_file)
n_messages = email.send()
}}}
