Does SIMS in fact wait for responses from each RBL that is queried?
I believe it does, from watching logs. Otherwise, what would be the point?
Well, it cannot wait forever. Something must time out, if a queried server does not respond. Otherwise, SIMS might not ever accept any mail, if just one RBL server is down. I guess my question should have been: What is the timeout on a RBL query and, if other RBLs report no problem, will SIMS accept mail in the absence of some responses?
Yes. The DNS resolver in the OS has a timeout that I think is 60 seconds on MacOS. SIMS only rejects if there is an actual hit on a blacklist, not if there is a failure of the list's server to respond.
