queue-admin is a bash2 shell script for managing the mail queue of the qmail MTA. It can provide a summarized list of the messages in the queue, optionally filtered by number or by whether a message is local or remote. The messages themselves can be listed, viewed, or deleted by the same criteria. It can also search for expressions within the messages, and can return the entire email or only the line where the expression was found. The output is colorized.
