I have not yet looked at this in detail (may do so later today), but that is Exim's standard loop-breaking algorithm. It automatically skips a router that has previously processed the current address. So if a router redirects A->B and next time redirects B->B then the third time it will skip because it has already processed B. -- 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-dev Exim details at http://www.exim.org/ ##
