Last year on Friday before the week of July 4, we had a user create a vacation rule and she checked "Reply to External Users." She had listed her work email at her apartment complex. Right after she left work that day, her apartment complex emailed her saying the office would be closed for the week of the 4th. Her rule replied that she was on vacation, the apartment complex replied the office would be closed... and you get the picture. When she got back, she had received 80,000 emails and had sent 80,000 emails. We turned off "Allow replies" on Rule-generate message but now some would like it turned back on. Is there a way to prevent a loop such as this? If so - how? Thanks! Susan
