Projects / Mireka


Mireka is a mail server with SMTP, Mail Submission, and POP3 services. It can also be used as an SMTP proxy. As a proxy, it can help to prevent or diagnose mail problems, like outgoing backscatter spam. It provides detailed logging, basic mail traffic statistics, tarpit to prevent email harvesting, and loop detection. It can filter email by DNSBL, SPF, mail size, local domains, and recipients list. Local recipients can be specified using regular expressions. TLS is supported for incoming connections. Aliases, forward lists, and very simple mailing lists can be configured in XML. Custom filters and other components can be written in Java, and they can be easily implemented and installed.

      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.
