Projects / PowerMail


PowerMail is a redundant and distributed system for receiving mail via SMTP and storing it for users to access with POP. The way PowerMail works is quite unorthodox, and its design emphasizes speed and efficiency. Modified Maildir mailboxes allow PowerMail to employ hardlinks to save diskspace and deliver messages with thousands of recipients instantly. PowerMail can operate self-sufficiently or cooperate with a regular MTA to support mail forwarding.

        Release Notes: This is a large release with tons of bugfixes and usability enhancements. Additionally, generic LDAP support was added, which should allow PowerMail to speak to most LDAP schemas currently in use. Building the MySQL, Oracle, and PostgreSQL userbases has been made easier because of more sensible path and filename defaults.

          Release Notes: The code is now available under the GNU GPL. PostgreSQL and Oracle drivers have been added. This is currently a source only release, but binary builds are expected to return shortly.

          •  13 Sep 2002 12:49

            Release Notes: This version now runs the .TK toplevel domain mailforwarding and is the result of the work needed to make PowerMail scale to the 1000+ concurrent connections sometimes needed to handle the .TK mailflow. Furthermore, the Oracle userbase can now read its SQL query from the configuration instead of being hardcoded.
