Specify the interval, in hours, you wish for the autoresponder to wait between responses to the same email address.
* For example, if you set up an autoresponder with an interval of 24, and you receive an email from
john@example.com at 8 am on Monday, the autoresponder will respond to his message immediately. If, however,
john@example.com continues to email you throughout the day, the autoresponder will not send him another response for 24 hours after his initial email (in this case, 8 am Tuesday). If he emails you again after the 24-hour interval expires, he will receive an auto response.
