To process more emails in less time, you can now scale email listeners to meet your organization's load requirements. This enhancement is useful for organizations that receive a high volume of emails per day or that manage thousands of email accounts.

You can increase the throughput of your email listeners by specifying how many concurrent threads must process emails per node. For example, specify 10 concurrent threads to simultaneously process 10 emails.

You configure concurrent threads on the Email listener rule form, as shown in the following image.
