This had happened serveral times before: My qmail+ezmlm mailling-list server suddenly stopped all delivery. No mail could be send from remote to local, local to remote, or even local to local. All qmail-inject return success. And no error messages were logged. But then I log in as root, and delete all files in the queue directories: /var/qmail/queue/remote/0 - 22/* /var/qmail/queue/mess/0 - 22/* /var/qmail/queue/local/0 - 22/* ....etc. etc. The delivery will be funcional again! Even those mails that were delivered and blocked BEFORE I delete the queue will reach its destination. What was all this about? How do I prevent this from happening again?
