Mail Queue

The mail queue is where mail is put before it is processed for local or remote delivery. The mail queue typically operates smoothly without interaction but every once in a while, the server administrator may need to take action to unclog it. This typically happens in a scenario where either a malicous user is spamming from a local address to remote servers or a remote server is spamming users on a local domain. In addition, exploitable PHP scripts could allow someone without server access to use your server to send spam, filling the queue with tons of messages.

4. Locate the Queue section.

6. If there are no messages in a given queue, you will see No Messages In Queue.
7. If there are messages in a given queue, they will be displayed in a table in the Queue section.

Then, you will want to actually see the contents of messages if you can't determine if a message is spam from the sender/recipient.

Expiring a message will result in the message being deleted the next time the mail queue is processed. Normally messages in the queue will expire after 1 week but you may wish for that time to be shorter on a given message.

2. Click the Mail Server menu item if it is not already open.

The following procedures will explain how to purge (delete) messages from the local, remote, and todo mail queues. If a queue is purged, it will not be processed in any way.
