In case of empty user data in SMTP settings will cause sending email without sender address.
In this case the email could be rejected by policy, or catch by the spam filter.
Separated sender address field could be added for the SMTP settings, and use that as sender address when sending mail.
Even if no need to authenticate on SMTP server.
Another possible solution:
If password field is left empty in SMTP settings, then use SMTP without authentication, but the sender address could be what specified in SMTP username field.
