messages can be retried at a later time. (e.g., An SMTP 4XX error code.)

Soft Bounces are logged in the IronPort Text Mail Logs (mail_logs) and in the Bounce Logs (bounces). The
bounce log records all information pertaining to each bounced recipient. In addition, if you have specified
message size to log or setup logconfig > logheaders, the message and header information will appear after the
bounce information.

The ESA will retry delivery based on the bounceconfig parameters as configured. Delivery will be

By default, the system generates a bounce message and sends it to the original sender for each hard bounced
recipient. (The message is sent to the address defined in the Envelope Sender address of the message
envelope. Envelope From is also commonly referred to as the Envelope Sender.) You can disable this feature
and instead rely on log files for information about hard bounces.
