Yes, that makes a certain amount of sense, I suppose. Especially as it's more _likely_ to be a spammer if they're connecting the secondary MX while the primary is actually alive. But still, there aren't that many things that the primary MX would be rejecting for that the secondary couldn't also reject for, based on the same information. Except that the secondary might also have to pander to the "I _like_ my daily pr0n-spam" nutters, I suppose :) -- dwmw2 -- ## List details at http://www.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
