Release Notes: Sender Rewriting Scheme (SRS) was implemented for SPF-compatible forwarding. Mireka can be configured to send "delayed" DSN reports on temporary failures.
Release Notes: With the addition of the POP3 service for mail retrieval, Mireka is now a basic but complete standalone mail server. Other new features in this release: aliases, forward lists, and very simple mailing lists. The new POP3 importer imports mail on startup. This is useful for migration. TLS support is added to every service, except for outgoing SMTP connections.
Release Notes: This release is able to relay mail to different back-end servers depending on the recipient or recipients. It is possible that a single email with several recipients is relayed to more than one back-end server. This feature is required, for example, to easily integrate with the SubEtha mail list manager.
Release Notes: Now it can also be used as a standalone, send-only mail server. It uses file-system based mail queues.
Release Notes: A message submission agent (RFC 4409) proxy is added. Authentication is done by IP address or by name-password pair through SMTP authentication.
