That's your basic problem; go beat up your ISP or move to a better one - because, big-G will proceed in the future to apply the same constraints to ipv4. My prediction; I have no special knowledge.

One way: dns_ipv4_lookup domain list; lookup only A-records for these domains, not AAAA also. eg: dns_ipv4_lookup = gmail.co (of course, subject to G moving their MX's around). http://exim.org/exim-html-current/doc/html/spec_html/ch-main_configuration.html -- 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/
