Final Answer:
The number of delivery attempts required to send Warning Messages and Bounce Messages varies depending on the email service provider's settings. Typically, Warning Messages are sent after multiple unsuccessful delivery attempts, usually around 3-5 tries, while Bounce Messages are generated after a set number of failed attempts, often around 5-7.
Step-by-step explanation:
Determining the number of delivery attempts for Warning and Bounce Messages involves the email service provider's configuration settings. Warning Messages are usually triggered after a few unsuccessful delivery attempts, typically set between 3 to 5 tries. These attempts occur when the recipient's server is temporarily unavailable or the mailbox is full. The system retries sending the email for each attempt within a certain timeframe, before generating a Warning Message to notify the sender about potential delivery issues.
On the other hand, Bounce Messages indicate a permanent delivery failure after a set number of unsuccessful attempts, commonly around 5 to 7 tries. These failures might occur due to invalid email addresses, permanent server issues, or other reasons that prevent successful message delivery. Once the specified number of attempts is reached without success, the sender's server generates a Bounce Message to inform the sender about the delivery failure.
Changing these attempt thresholds typically requires access to the email server settings or configurations. Email administrators or users with access to the email service provider's interface can modify these settings to adjust the number of attempts before triggering Warning or Bounce Messages. However, this process might vary based on the specific email service used and the level of access granted to users.
