The mail backup today was caused by someone who had vacation setup and then sent mail to themselves causing an infinite loop. I'm sorry it took a while to find this but by the time I became aware of it there were so much list mail backed up, and that combined with e-mail I got from Jimmie lead me to believe there was something wrong there (like a list belonging to an account that has been deleted). Chasing the list problems did not prove fruitful, but I did eventually chase down the cause. If anybody knows of a good working vacation program, that unlike Sun's, is smart enough not to send mail to itself; please let me know where to obtain same. Thank you!
