Custom Sender Email Address for Frappe Email Delivery Service

[pasan93]

I've noticed that when I send an email using the Frappe email delivery service, the sender's email is displayed as mail.frappe.cloud. I'd like to customise this to reflect the original sender's email address.

Is there a configuration or setting that can be adjusted to achieve this? If not, could this feature be considered for a future update?

Thanks in advance for your assistance.

It only appears in M365 (Outlook), but in Gmail, it shows the original sender's email address as expected.
