To add or modify an autoresponder:
f you wish to schedule an autoresponder message, select Scheduled, and you will see a calendar from where you can set the schedule.
You have the option to configure how many times an auto-response message will be returned to a sender within a given period of time. The default setting is 5 responses per 3 hours. This means that if the same sender sends multiple messages to your address, they will only receive five automated responses within 3 hours after the first message. The maximum response interval is 2 messages per 1 hour.

No autoreply messages are sent for emails that are flagged as spam and moved to the Junk Mail folder. This ensures that automatic responses are delivered only for legitimate incoming mail.
