Does "\root" do anything in /etc/aliases?

view full story

http://serverfault.com – I've found on a couple servers that have the following entry in /etc/aliases: root: \root,[email protected] I can't find \root used in any documentation. Does \root do anything? Could it be a syntax error? note: You can send mail to /dev/null like this, but I can't find what the \ does: root: /dev/null (HowTos)
