You are starting the daemon as root. And tell it to setuid to the user
"spamd". I believe this is perfectly normal. Btw, see 'man spamd' for
the -u option.

Only the child processes, which correctly setuid'd, will process
messages.

The master process (which does not scan messages, but care about its
busy children) will read that data. So you want to ensure it's readable
by that user.

FWIW, if you would not explicitly specify the -u option, the child
spamds would setuid to the user calling spamc.
