| | | | | | | | | | traps. - Change count to size_t to avoid a size_t -> int conversion. - Since configure_spamd always returns 0, change to void. - Since configure_spamd now returns void, remove unreachable logging statement. OK ckuethe and deraadt, initial diff from fgsch@ and OKed by beck.

* A couple of spamd improvementsbeck2007-03-262-19/+40
| | | | | | | | | | | | | | 1) Implement the NOOP command, which now seems necessary for certain windows mail wrappers and sender verification schemes. Tested by me and sidcarter@symonds.net, who noticed the problem on his site. ok millert@ 2) Change the behaviour of the maxblack parameter, instead of hanging up immediately on new blacklisted connections when the maxblack parameter is reached, we instead make spamd not stutter at them, so the connection is instead completed quickly. This seems to handle peaks and spikes much better than the old way of doing this. ok deraadt@, with some man page changes by jmc@

* Don't delete grey entries when whitelisting. They expire anywaybeck2007-03-141-6/+1
| | | | | | | and this hides the evidence. Avoids a potential race when using -M traps where a retry comes in between deletion and whitelisting. ok millert@

* Database synchronizaton for spamd/spamlogdbeck2007-03-047-13/+912
| | | | | | | | | | | | | | | | | | | | | | | | | | | This adds an HMAC protected synchronization protocol for use by spamd and spamlogd. - spamd can receive updates from other hosts for GREY, WHITE, and TRAPPED db entries, and will update the local /var/db/spamd accordingly. - spamd can send updates when it makes changes to the GREY or TRAPPED entries in the db to other hosts running spamd. (Note it does not send WHITE entries because the other spamd will see the GREY changes and have complete information to make appropritate decisions) - spamlogd can send updates for WHITE db entries that it performs on the local db to other hosts running spamd, which will then apply them on remote hosts. note that while this diff provides synchronization for changes made to the spamd db by the daemons, it does *not* provide for sychonizing changes to the spamd db made manually with the spamdb command. Synchronization protocol and most of the work by reyk@, with a bunch of the spamd, and spamlogd stuff by me. testing mostly at the U of A, running happily there under big load. ok reyk@ jmc@
