At least on my box, as long as you give slocal -user when it's invoked,
Strike that, reverse it. As long as -user *is not supplied*, presumably
due to these lines of localmail:
443 /* last resort - deliver to standard mail spool */
444 #ifdef SLOCAL_MBOX
445 return usr_file
You might try telling slocal to be verbose, in which case it might
say what was going wrong, or alternatively run under a debugger and
see why status is being set to -1...
This has been suggested before, but it's not the most end-user friendly route.
# slocal -debug
