These are system accounts, necessary so that programs can run as non-priviledged users. If you are gettig spam to them (not uncommon), set up the appropriate rules in /etc/aliases - it depends on your MTA what the syntax is, but exim4 uses :fail: <some string>, sendmail uses :error:nouser <some string>, and I'm sure others do similar things. You can of course, redirect them all to root, as many people do. -- -------------------------------------------------------------------------- | Stephen Gran | mophobia, n.: Fear of being verbally | | steve@lobefin.net | abused by a Mississippian. | | http://www.lobefin.net/~steve | | -------------------------------------------------------------------------- Attachment:
