Postfix: Delete Deferred

Postfix is probably the most common email server available on a Linux system. Email that fails to make it to it's destination address is stored on the system for subsequent retries. The system I'm working with at the moment is a Mac OS-X Server and the data files are stored in /var/spool/postfix subdirectories.

It occasionally becomes necessary to delete the content of the deferred mail folder. To accomplish this you'll need adequate permissions or SUDO access. Simply execute the following command;

postsuper -d ALL deferred

This command works on all the data directory structure for postfix. I.e.; "postsuper -d ALL defer" will empty the content of the defer directory.

Reference the Post Super documentation at postfix.org.
