How many of you set up “out of office” messages for those who send you e-mail while you’re, well, out of the office? I can’t deny their usefulness for providing people with immediate notification of your unavailability, but for some reason they annoy the heck out of me. I’m glad to know I’m not the only one who doesn’t use this feature.

And now it seems they might be bad for you. Apparently, would-be criminals are buying up lists of e-mail addresses to find out details of vacation absences. Once they have the list, it’s a pretty simple process to determine the address of those “out of office” individuals.
