The messages-injected variable counts the number of messages that have been injected into the database since the server started.
Injection usually happens when a message is delivered from a remote source to an Archiveopteryx database. It also happens in some other cases: when a local user uses SMTP submission to deliver to a remote address, when a vacation response is sent, when an IMAP client uses the Append command, and when the aoximport or deliver programs inject mail into the database.
Copying mail from one folder to another does not cause injection. When one message is sent to several destinations, messages-injected counts the message only once.
