And below is output from my test host: looking up host name for 2602:ff1c:0001:0080:0000:0000:0000:0050 DNS lookup of 0.5.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.8.0.0.1.0.0.0.c.1.f.f.2.0.6.2.ip6.arpa. (PTR) succeeded Reverse DNS security status: unverified IP address lookup yielded "mta4.pr.judicialwatch.org" DNS lookup of mta4.pr.judicialwatch.org (AAAA) succeeded DNS lookup of mta4.pr.judicialwatch.org (A) succeeded checking addresses for mta4.pr.judicialwatch.org Forward DNS security status: unverified 2602:ff1c:1:80::50 OK The difference is that your Exim does not do IPv6 (AAAA) record lookup. Try to locate the reason... I'd propose to compare with pure Exim setup. -- Eugene Berdnikov -- ## 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/
