Every time I post to a large mailing list, I inevitably get a huge pile of nice messages from some guy called Mr MAILER-DAEMON, telling me that half the people on the list don't actually exist any more. I also get quite a few messages from helpful Notes systems telling me that some of the list subscribers are on holiday. Which I really care about. I do.

But today, the following bounce-message won the award for Mailing-List Stupidity of the Year (Well, the year so far. Which really means this month.)

Thank-you! Thankyou for subscribing to a mailing-list, and then bouncing every message you receive from it because you don't trust it to send you mail. You GENIUS!
