This option determines how many days a user has to not
bounce messages before their bounce count is set back to 0.
You may want to change this number
if you post infrequently to your mailing list. For example, if you post once a
week, you should set this Bounce Reset number to longer than once a week, such
as 8 or 9.
If you post once a month, you
should set this number to longer than a month, such as 35.
