We think this would be a good improvement for setups where the mail server does not require authentication or does not support it. It would provide more flexibility for the users.
Our own use case is the first one. All our servers send without authentication and the connector is limited to servers only. The reasons for this are:
- It’s overhead to manage/maintain accounts for such use cases
- Costs for maintaining an additional mailbox
This is also the first software we encountered that does not provide an option to send mails without authentication.
