Hello, Apache James : 3.5.0
I have a non functional requirement which I am trying to implement through Apache James which is “ A maximum of ( very low number ) emails per hour is allowed ”. I am currently using the default FileMailQueue approach while trying to adhere to ( very low number ) emails per hour requirement. I have configured the following CONNECTION_LIMIT : Set the maximum simultaneous incoming connections for this MTA service : 10 CONNECTION_LIMIT_PERIP : Set the maximum simultaneous incoming connections per IP for this MTA service : 10 DELIVERY_THREADS : The number of threads that should be trying to deliver outgoing messages : 10 SPOOL_THREADS : This is a required positive integer element. It specifies the number of threads the SpoolManager will use to process messages in the spool. This parameter tends to substantially impact performance, so it is advisable to tune it in production configurations. : 30 This meets my email per hour allowed requirement, but the functional component can peak at 216 emails / s so we get lost emails. When the following is done, CONNECTION_LIMIT : Set the maximum simultaneous incoming connections for this MTA service : 20 CONNECTION_LIMIT_PERIP : Set the maximum simultaneous incoming connections per IP for this MTA service : 20 DELIVERY_THREADS : The number of threads that should be trying to deliver outgoing messages : 10 SPOOL_THREADS : This is a required positive integer element. It specifies the number of threads the SpoolManager will use to process messages in the spool. This parameter tends to substantially impact performance, so it is advisable to tune it in production configurations. : 30 We are blowing the emails per hour limit. So the question is, do I need to do any custom queueing ? or configuration to enable throttling ? Amlan. --- This e-mail may contain confidential and/or privileged information.
