It seems that the only sensible thing to do is to ignore the additional section completely, and that is what I plan to do. I have not decided whether to be more elaborate than that or not, but I suspect that it is not worth doing anything. Busy systems should have "nearby" DNS servers so that the additional queries will be cheap; for unbusy systems it won't matter much. I have not looked at the source, but the patch should be trivial; just delete (or skip) the code that processes the additional section. I do not expect to actually look at this for one or two or three weeks. I have been on vacation over Christmas and New Year, and this week is a short one in which I want to do documentation work. Thereafter I am planning on a PCRE blitz, which will probably last most of January. -- 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/
