But Exim 4 thinks so: [EMAIL PROTECTED] router = dnslookup, transport = remote_smtp host capsaicin.mamane.lu [2001:888:19f0::2] MX=9 host capsaicin.mamane.lu [2001:888:19f0:2::2] MX=9 host quorn.mamane.lu [213.84.114.29] MX=10 host tofu.mamane.lu [2001:888:19f0:0:210:5aff:fe45:9b17] MX=11 host a.mx.conuropsis.org [2001:838:300:241::2] MX=30 host a.mx.conuropsis.org [217.115.192.216] MX=30 My local BIND omits a few AAAA records from the answer to mamane.lu/IN/MX to bring it below the 512 byte limit (it may do so, after all it's just the addtitional section). I would have thought that Exim queried for AAAA records if necessary, but this seems to be wrong. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
