Deleting old emails from the mail queue

Hello team,

I need help in clearing the mail queue in one of our Centreon pollers. For some reason we have hundreds of old/stale mails in the queue. I use the command “mailq” to see all these old emails in the queue.

I need to clear or delete these old emails from the queue, but I am not sure in which folder or directory to check and clear this...also can please advise the correct comment to delete this?

Thank you,

Crisanto
