actually, the -t doesn't have anything to do with the rbl lookup. the -t argument is how long rblsmtpd will hold the smtp conversation active before simply dropping it.
ah, indeed you are correct, sir. still, doesn't hurt to keep the convo timeout low too - since most of the connections really couldn't give a rat's-ass what the mailserver replies with!
There is a way to change the timeout of the rbl lookup, I believe it was covered on the qmail list a month or two back :)
cool. i'll be checking that out.
