Procmail as local delivery agent

[Roy C Bixler <rcb@press-gopher.uchicago.edu>]

I have just been tinkering with setting up 'procmail' as the local mail
delivery agent using the example entries in 'scheduler.conf' and
'sm.conf'.  However, I find it fails to deliver local mail since the '$u'
in 'sm.conf' expands to 'user@host' and 'procmail' is called like this: 

procmail <other args here> -d user@host

If I remove the '@host' part, the delivery is successful.  But if the
message gets to the 'procmail' delivery method at all, then it's already
local and '@host' is superfluous anyway.  Is there any way in 'sm.conf' to
specify to pass only the username to 'procmail'?
