For no reason that I've been able to discern, for months and months now, nearly any use of ipv6 as an email transport has ended up getting the ipv6 address blocked in spamhaus's SBL listing, and thus a lot of email has been blocked. IPv4, seems ok, but for all I know whatever's triggering it only triggers when ipv6 is used. So I've given up on ipv6 and switched it over to ipv4 only.
If anyone has any insight on how to run a dual stack email server correctly nowadays, please contact me offlist?! If anybody here actually needs to talk to this server over ipv6, well..... -- Dave Täht CTO, TekLibre, LLC http://www.teklibre.com Tel: 1-831-205-9740 _______________________________________________ Cerowrt-devel mailing list Cerowrt-devel@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cerowrt-devel
