When using an SMTP connection, not all fields are used when sending an e-mail with send_mime_email(). This fix addresses this by taking values from the connection, using the original values as a fallback.

I think in general it should be part of email_backend and implemented in the SMTP provider, by the same way it implemented in airflow.providers.sendgrid.utils.emailer.send_email, airflow.providers.amazon.aws.utils.emailer.send_email backends

In this case we could keep core in-depend on Provider-specific implementation.
But let's wait and see what the other says
