dns_means_nonexist makes a temporary error look like "not found". +ignore_unknown causes "not found" to be ignored, so these two options do interact. But +ignore_unknown on its own won't stop a defer because when a DNS lookup gives a temporary error, you don't know if the host is unknown or not. Consider a major network failure that causes lots of nameservers are unreachable... -- Philip Hazel University of Cambridge Computing Service Get the Exim 4 book: http://www.uit.co.uk/exim-book -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
