Question: I'm using Exim mail server under CentOS Linux. How do I remove all messages from the Exim mail queue using a shell prompt?
Answer: Exim is a mail transfer agent (MTA) used on Unix-like operating systems. It aims to be a general and flexible mailer with extensive facilities for checking incoming e-mail.
To print a list of the messages in the queue, enter:
# exim -bp
To remove a message from the queue, enter:
# exim -Mrm {message-id}
To remove all messages from the queue, enter:
# exim -bp | awk '/^ *[0-9]+[mhd]/{print "exim -Mrm " $3}' | bash
Dallas Marlow, suggested following clean command:# exim -bp | exiqgrep -i | xargs exim -Mrm
