#33438: SMTPAuthenticationError in EmailMessage and EmailMultiAlternatives when
using 'Some Name <em...@gmail.com>' format for `from_email` while running
server locally

Here are my configuations:

''.env''
{{{
EMAIL_HOST_USER = 'ma...@gmail.com'
}}}

''settings.py
''
{{{
EMAIL_HOST_USER = os.getenv("EMAIL_HOST_USER")
}}}

This works just fine normally.

My issue is when I want to add a name to ''from_email'' using the accepted
format:[https://docs.djangoproject.com/en/4.0/topics/email/#emailmessage-
objects]
ie: "Customer Service <fr...@fred.com>" so the recipient sees 'Customer
Service' instead of just 'fred' or fred@... like this:

{{{
#!div style="font-size: 80%"
Code highlighting:
{{{#!python
email = EmailMultiAlternatives(
subject='subject msg',
body='testing',
from_email=f'Customer Service <{settings.EMAIL_HOST_USER}>',
to=[request.user.email],
)
email.attach_alternative(render_to_string('Campaign_Email_NEW.html'),
"text/html")
email.send()
}}}
}}}

I tired this in the shell of my live server and it worked!

BUT when I tried to run this in the shell or via postman when running the
server locally on my computer then I get a SMTPAuthenticationError, with
this info:

{{{
Exception Type: SMTPAuthenticationError at /api/campaign_mail/
Exception Value: (535, b'5.7.8 Username and Password not accepted. Learn
more at\n5.7.8 https://support.google.com/mail/?p=BadCredentials

}}}
