Delivery to Users

Any address in the list of addresses to the right of the colon that does not begin with a /, |, or : character is considered to be the address of a user. The address can be local or remote.

If that user address to the right of the colon is prefixed with (or contains) a backslash character (\) and the address is a local one, all further aliasing is suppressed (including reading the user’s ~/.forward file), and the message is delivered with the local delivery agent.
