A couple of spamd improvements
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@
