the -S option: by default spamd will 'stutter' (send one byte at the time at the -s seconds interval) for 10 seconds. Using the -S option, you can set the number of seconds the stuttering will last on connections from greylisted hosts before normal traffic parameters kick in. I don't think I've ever played with that. When I've looked at actual data, (such as when working on this piece bsdly.blogspot.com/2014/02/effective-spam-and-malware.html - the graph in the "Introducing greylisting" section) it looks like the vast majority of connections last less than 3 seconds and the next peak is at approximately the 400 seconds mark. - Peter -- Peter N.
