I would give every tenant in an multitenancy environment its own mail address for sending notifications.
Agree, that must have been a tenant specific setting for ease of administration. Voting up.
That say this is already achievable using separate notification method per tenant
like pdm_mail -F "firstname.lastname@example.org" -T "email@example.com"
then you assign this notification method to all users of that tenant
my 2 cents in the meantime
