It should use SIGCHLD and + a ioloop-based timeout. + - Add facility to trigger a temporary failure condition when a program + fails rather than an implicit keep. + - Add a method to implicitly pass environment variables such as SENDER and + RECIPIENT through the script socket service. +* Make testsuite much more exhaustive: + - Add support for testing the content of result actions + - Test as many error/warning/info conditions as possible. + - Review the specification documents and check whether the given requirements + are tested at least once. +* Fix ManageSieve proxy to recognize response codes from the backend and forward + them to the user if appropriate/safe. Probably means implementing a proper + ManageSieve client library. +* Test ManageSieve behavior thoroughly: + - Test pipelined behavior + - Test proxy authentication +* Code cleanup: + - Make address handling more uniform. + - Review all FIXMEs + +* Build a server with test mail accounts that processes lots and lots of mail + (e.g. spam, mailing lists etc.) + +Low priority items: + +* Implement extlists extension as a plugin +* Enotify extension: detect use of variable values extracted from the message + that are used in the method argument. RFC reports this as a security issue. +* Provide a solution for mail_get_headers_utf8 reparsing the whole message each + time it is called (header and address test; Timo might provide solution from + within Dovecot) +* Warn during compile if using non-existent folders. + +* Variables extension: implement compile time evaluation of constant values + - Detect assignment of too large constant values to variables at compile + time. +* Add development documentation, i.e. comment on library functions and document + the binary and byte-code format. +* Implement sip-message notify mechanism. + |
