Setruid spamd error on Aix

[Jose perez]

I run /usr/local/bin/spamd -u spam and i get this error: [143440] error: setruid() not implemented at /usr/local/bin/spamd line 877. setruid() not implemented at /usr/local/bin/spamd line 877. [86114] info: spamd: server successfully spawned child process, pid 143440 [86114] info: spamd: handled cleanup of child pid 307372 due to SIGCHLD [86114] info: spamd: handled cleanup of child pid 143440 due to SIGCHLD [86114] info: prefork: child states: [86114] info: spamd: server successfully spawned child process, pid 524290 [524290] error: setruid() not implemented at /usr/local/bin/spamd line 877. setruid() not implemented at /usr/local/bin/spamd line 877. If i don't use -u spam and i run it as root user, then i get another similar error to:  locker: safe_lock: cannot create tmp lockfile /root/.spamassassin/auto-whitelist.lock. Spamassassin is the last version on Aix 5.2. Any idea ?
