It certainly shouldn't be fatal -- and isn't necessarily even a mistake. For a long time, the primary MX host for infradead.org was 'phoenix.ipv6.infradead.org', which as you might guess from the name doesn't have an A record. There were occasional reports of Postfix getting confused, deciding that it actually resolved to 0.0.0.0 and thus to the local host, and failing to deliver the mail -- but other than that, it was fine. -- dwmw2 -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
