[jira] Resolved: (JAMES-1108) Rewrite ActiveMQQueue to use

Norman Maurer resolved JAMES-1108.
----------------------------------
Resolution: Fixed
Assignee: Norman Maurer
Done.. we now use BlobMessages for storing our Mail instances.. Everything except the MimeMessage get stored as JMS Property. The MimeMessage will get stored via an custom BlobTransferPolicy, which streams directly to the filesystem. With the new implementation we need a way less memory as before. Even while bombing james with 500 concurrent smtp clients I saw a heap usage of 70 - 90 mb only with the new implementation.
