That wasn't this case. We had an initial lookup for a SRV record, key starting _client._smtp. which didn't find a SRV record but did find a CNAME which had content _not_ starting _client._smtp and the lookup for a SRV using that content as key found no SRV record, either. -- Cheers, Jeremy -- ## List details at https://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/
