	Yes, there are some standard ways as documented in spamd(8)- they are

relatively new, so if your spamd is old you don't have them. see

the /etc/mail/spamd/alloweddomains, etc. etc.
	There is a quasi standard perl script which I have posted and is available

frequently referenced in the archives of this list, and has already been mentioned

twice in this thread.  it is not "standard" with OpenBSD because pieces of it

must be customized to be site specific, so it's not really a generic solution, but

it can do some things the generic stuff can't.
