How can i proceed ?

As usual, Milo, with any feature you're unfamiliar with, you must first do your homework:

1. Read the appropriate man page(s). In this case, start with spamd(8). Then, note the SEE ALSO section, that will point you to spamd.conf(5), spamd-setup(8), spamdb(8), and spamlogd(8).
2. Then, for guidance, read the many articles about spamd from the OpenBSD Journal: http://undeadly.org/cgi?action=searc...s=&query=spamd -- you will note that some of these articles point to feature changes, others are a variety of "how to" documents, and each has a related discussion that may also be helpful.
3. The misc@ archives can also be of great assistance. I like http://marc.info, other archives are also available. You'll have to do your own keyword searching of this, or of another openbsd misc@ archive.
4. Then, if you need further assistance, come back here and ask a specific question.
