Impact of updated cipher suites on Jira cloud and Jira Service Management

As a result, some of the TLS cipher suites that used to work earlier may now result in errors leading to unsuccessful incoming email connections.

This change will take effect on July 8, 2024. We recommend that customers review their existing web server and incoming email configurations and ensure they support one of the supported TLS cipher suites.

Note: This change will not affect customers using OAuth access.
