fowarding mail

[eugholz at ATHENA.MIT.EDU]

I'm trying to foward my mail from a Personal IRIS on which I have an account
to my main general-purpose account on a different machine.  The command that
I know of to foward mail is "mail -F destination" -- and this is what is 
documented in the man page on mail on the IRIS.  However, trying this on two
different IRISes has yielded the message "unknown flag -F".  I'd appreciate
any hints about fowarding mail through this or any other technique.  I have
seen references to using a ".Foward file", but have not found any documentation
about the proper format for such a file -- and trial and error isn't doing it
for me.
Thanks a lot,
Eugene Gholz
