4724: Optional usage DEFAULT_FROM_EMAIL for request mails


What version are you running?


Describe the enhancement and the motivation for it.

Our smtp server prevent sending mails with different sender mail (argument from_email of EmailMessage) and allow only own account for this field

Please provide any additional information below.

That line use mail of review/request user.
For now we change this line to from_email=settings.DEFAULT_FROM_EMAIL
but we want to have option for this in admin panel.
