If the .forward template in 5b above doesn't work the following alternatives 
might be helpful:

In a perfect world:
	"|exec /usr/local/bin/procmail #nancym"
In an almost perfect world:
	"|exec /usr/local/bin/procmail USER=nancym"
In another world:
	"|IFS=' ';exec /usr/local/bin/procmail #nancym"
In a different world:
	"|IFS=' ';exec /usr/local/bin/procmail USER=nancym"
In a smrsh world:
	"|/usr/local/bin/procmail #nancym"

These formats can be tried in different combinations, the leading "| can
be tried as |" instead, or vice versa.

NOTE
====
If your system uses procmail as its local delivery agent, you do not
need a .forward file; simply having a .procmailrc files suffices.  To
find out if procmail is the local delivery agent, ask your system
administrator.
