Simscan is a single C source file available here:
http://www.inter7.com/?page=simscan

It goes on a bit but is quite easy to read and there's a README
documenting its arguments in the documentation wiki. Simscan calls spamc
rather than spamassassin. What it does depends on a set of options:

 --enable-spam=y|n                 Turn on spam scanning. default no.
 --enable-spam-passthru=y|n        Pass spam email thru or reject
                                   Default: disable (reject)
 --enable-spamc-user=y|n           Set user option to spamc.
 --enable-spam-hits=number         Reject spam above this hit level.
                                   Default 10.0
 --enable-spamc=PATH               Full path to spamc program.
 --enable-spamc-args="ARGS"        Arguments to pass to spamc.

The --enable-spamc-user controls whether it runs in per-user mode. The
-u option is always used together with any spamc arguments defined with
the simscan --enable-spamc-args="ARGS" option, so the OP needs to read
his qmail config to see what, if any, overrides have been supplied.
