Recent releases

  •  28 Jan 2014 16:01

    Release Notes: This release is a major update which adds 12 new options, renames three options, and removes five options. The meaning of "whitelisted" is changed to allow whitelisted connections to bypass spamdyke's filters but not to automatically relay (unless allowed for some other reason). DNS searches for valid sender domains will now prioritize MX records before A records. Full recipient validation is now available. Sender addresses can be rejected if they don't match the username given during authentication (or if the domain doesn't match). Many bugfixes have been made.

      Release Notes: This version fixes a couple of processing bugs in the new header blacklist filter and an access violation that can lead to crashes. The header blacklist should is safe to enable now.

        Release Notes: This version adds the ability to filter messages based on the content of their headers. Please note that enabling this feature should be accompanied by disabling the use of the "softlimit" program. In addition to fixing some small bugs and a compiling error on Debian 7, it also fixes a series of major bugs which could lead to buffer overflows. Depending on spamdyke's configuration, these could cause remotely-exploitable security holes. Users should upgrade immediately.

          Release Notes: This release fixes a few bugs and extends the log messages to include more information when a blacklist is matched.

          •  06 Feb 2011 05:46

            Release Notes: This version adds a new option to select which SSL ciphers can be used and several options to control how DNS queries are performed. It fixes several bugs, including one that allowed open relaying for specially malformed addresses, one that caused timeouts instead of clean exits, and one that caused crashes if configuration files were empty.
