Problem to solve
Many organizations use internal SMTP relays that do not require authentication. These servers are configured to be accessible only within the organization's internal network, which eliminates the need for username and password authentication. Currently, GitLab's Service Desk requires SMTP credentials to be configured for sending out notifications, which is not feasible for organizations using unauthenticated SMTP relays.
Proposal
Allow GitLab users to configure the SMTP settings for Service Desk without requiring a username and password. This would be particularly beneficial for environments where email relays are secured by network rather than by credential authentication.
Intended users
Organizations that use an internal, secure, non-Internet-exposed SMTP relay for sending emails.
