Dspam needs to know who is calling it, so it can check if it's a
trusted user. Real question is of course why you are trying to run it
as a numeric uid that does not belong to any system account :)
If you have a valid reason for doing that (can't really think of any,
but it's your call), then try wrapping the call to dspam in the
antispam config with sudo: run the command (passwordless) as an
existing system user/group.
