| what you mean with how I see permanent errors ? |
| unknow users are in ValidRcptHandler |
| but if someone would just ignore the 5xx return code on rcpt and suply the data it would return a permanent error |
| so yes it could be in there too |
| maybe we should only count the first 5xx in a transaction |
| |
| for the rejected message, I would except to be counted as ok in the stats |
| why |
| it's not an smtp protocol error |
| 5xx is an error |
| thats the whole point of the stats |
| see how many messages are rejected via permanent error and how many via temporary error |
| what's the difference between permanet and temporary ? |
| temporary will get try to redelivered later |
| like greylisting is temporary --> |

| <p>You can monitor James Server via JMX.</p> |
| |
| |
| <p>The managed objects are exposed from localhost only (for security reasons) on the following URL:</p> |
| |
| |
| <p><tt>service:jmx:rmi:///jndi/rmi://localhost:9999/jmxrmi</tt></p> |
| |
| |
| <p>Simply launch jconsole to access the exposed attributes and methods. |
| Active Connections active per component, limits,... can be displayed and following services can |
| be monitored:</p> |
| |
| |
| <ul> |
| |
| <li>IMAP</li> |
| |
| <li>POP3</li> |
| |
| <li>SMTP</li> |
| |
| <li>LMTP</li> |
| |
| <li>RemoteManager</li> |
| |
| <li>DNSService</li> |
| |
| <li>Queues</li> |
| </ul> |
| |
| |
| <p>If you want to access the JXM server from a remote location, you can <a href="config-system.html">configure |
| the hostname and port</a> on which James listens to.</p> |
