Hi Michael,

I do use IPv6, and my network interfaces are properly configured :

lo0: flags=1008049<UP,LOOPBACK,RUNNING,MULTICAST,LOWER_UP> metric 0 mtu 
16384
options=680003<RXCSUM,TXCSUM,LINKSTATE,RXCSUM_IPV6,TXCSUM_IPV6>
         inet 127.0.0.1 netmask 0xff000000
         inet6 ::1 prefixlen 128
         inet6 fe80::1%lo0 prefixlen 64 scopeid 0x5
         groups: lo
         nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
igb0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 
0 mtu 1500
options=4a520b9<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,WOL_MAGIC,VLAN_HWFILTER,VLAN_HWTSO,RXCSUM_IPV6,HWSTATS,MEXTPG> 

         ether d0:50:99:c1:12:79
         inet 192.168.100.144 netmask 0xffffff00 broadcast 192.168.100.255
         inet6 fe80::d250:99ff:fec1:1279%igb0 prefixlen 64 scopeid 0x1
         inet6 2a01:e0a:xxxx:xxxx::144 prefixlen 64
         media: Ethernet autoselect
         status: no carrier
         nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>

I can do a traceroute6 to ipv6.google.coom

I've even rebooted my server with no success

Amavis worked fine until I upgraded Perl and dependencies

Regards,

Xavier
