Bounce? No. The servers trying to send mail to your server will retry for up to, typically, four or five days, before they bounce the mail back to the sender.
Mail was written to be resilient against network downtime.

The sender MUST delay retrying a particular destination after one
attempt has failed. In general, the retry interval SHOULD be at
least 30 minutes; however, more sophisticated and variable strategies
will be beneficial when the SMTP client can determine the reason for
non-delivery.
Retries continue until the message is transmitted or the sender gives
up; the give-up time generally needs to be at least 4-5 days. It MAY
be appropriate to set a shorter maximum number of retries for non-
delivery notifications and equivalent error messages than for
standard messages. The parameters to the retry algorithm MUST be
configurable.Thanks though, I learned something :)
Regardless of what we call it - the sender would get a copy back with a message not containing the word 'bounce' that says it failed to send, right?
