pfqueue

If you're an administrator looking for a console-based tool to handle MTA queues, pfqueue is the software for you. This tool provides a ncurses interface for postqueue/mailq/postsuper/exim4, without adding any particular functionality beyond what the MTAs themselves provide. The aim of this tool is to make it easier to manage MTA queues, offering a real-time queue scanner that shows per-queue lists of existing messages; users can then choose to show, delete, put on hold, release or requeue messages. For example, this feature can be helpful when you want to investigate sudden increases in your deferred queue.

A few requirements are needed before you can install pfqueue, such as the Postfix and ncurses library. Once installed, pfqueue can be compiled in a straightforward way: just `cd' to the directory containing the source code and type `./configure' to configure the package for your system, followed by `make' to compile the package. If you wish to run any self-tests that come with the package, type `make check'. You may also choose to install data files and documentation by typing `make install'. If you want to remove program binaries and object files from the source code directory, type `make clean'. To remove the files that `configure' created, type `make distclean'. For developers, there is also a `make maintainer-clean' target to regenerate files that came with the distribution.

The most recent version of pfqueue focuses on the socket backend and has improved remote monitoring capabilities to monitor MTA queues more effectively. In addition, reverse sorting functionality has also been added to this software. All in all, pfqueue is a well-designed, efficient tool for managing MTA queues from a console-based interface.
