It is possible.

When run in greylisting mode, spamd will run in the normal mode
for any addresses blacklisted by spamd-setup(8).  Connections
from addresses not blacklisted by spamd-setup(8) will be
considered for greylisting.  Such connections will not be
stuttered at (though see the -S option above) or delayed, and
will receive the pleasantly innocuous temporary failure of:

   451 Temporary failure, please try again later.

in the SMTP dialogue immediately after the recipient is
specified.  spamd will use the db file in /var/db/spamd to track
these non-blacklisted connections to spamd by connecting IP
address, envelope-from, and envelope- to, or "tuple" for short.
