Not so much if first all of the additional section is tried, and extra queries only been done of all of those fail -- a more rare situation I'd say. There are more queries though when a mail is failing for a while, but in that case, it's every time for the same domain, so the local DNS server has the relevant answers cached. --Jeroen -- Jeroen van Wolffelaar [EMAIL PROTECTED] http://jeroen.A-Eskwadraat.nl -- ## 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/
