route

ROUTE  -  forward mail delivery to another address

Usage:  ROUTE [address]

The ROUTE command redirects all incoming mail automatically.  A file named
  .forward is created in your home directory to hold the forwarding address.
  The ROUTE command with no address cancels routing.

A typical use of ROUTE is to direct your mail to someone else while you 
  are on vacation.  If you have more than one userid, you could ROUTE
  so that all incoming mail goes to one of them.

Examples:
    Send>route abc		#to the id abc
    Send>route abc@cuvmb	#to an id on another machine at CU
    Send>route abc@xyz.bfu.edu	#to an id at another university
    Send>route			#back to me
    Send>status			#shows my routing (among other things)
   
Valid addresses for routing are of the following forms:
    userid	  --Any userid on the same machine.
    userid@host   --Any userid on another system.  host: for Columbia, 
  	            usually the machine name alone; for Internet, 
                    domain name format; for Bitnet, node.bitnet
    \myid         --Your own userid (to include yourself in a routing).  
                    A backslash \ is recommended to avoid looping.
You can specify a list of addresses separated by commas.
Do not use the forms *filename or @filename, or an alias you DEFINEd,
or . (period) to mean yourself.

Advanced users: To route into a file, you must create the file first and set
mode 4000 (u+s) (e.g. chmod 4600 to get protections -rws------).  In the 
route command, specify the full path to the file from root, e.g. "route 
/f/u1/d00000/myid/filename".

To circumvent someone else's routing, send to \\userid.
