A related event that happened recently to my girlfriend's dad: He was on vacation and had his Blackberry or Outlook autoresponder set to respond to every message (not just once per sender, as I think is normal). Anyway, he bought a movie ticket online and they sent him an automated email asking not to reply. His autoresponder responded, and the auto-reply responded in turn asking him not to email. He turned his phone off after about 10,000 messages (he was in the movie) and didn't get resolved until he visited the office IT the following Monday.
Haha That's a great story, thanks for sharing. I can only imagine him wondering what the hell happened in the office when he saw 10,000 unread messages on his phone! Haha
