In this case the spamd child process drops its privileges from root to the user running spamc or the user specified by spamc -u. This allows spamd to access home directories without running as root. Probably what's happening is that as $local_part@$domain isn't a unix user, spamd is overriding it with the unix user "nobody" to avoid scanning an email as root. You should be running spamd with "-u spamd" which causes spamd to drop its privileges to the unprivileged user spamd after it has bound to the default port (it's usually called spamd, but your spamassassin package may have created some other user for this purpose). When you do this, the user in spamc -u can be treated as a virtual user.
