That needs to be fixed in SpamAssassin. Haven't looked at it yet.

Don't remember details, I guess it just goes along the fact that practically all FreeBSD ports with a config option for controlling ipv6 have this option turned on by default nowadays. With seven /8's remaining in the IANA pool (2%) and about 10% remaining space in APNIC, ARIN and RIPE it seems prudent to ship any new software with IPv6 enabled by default, considering how long it takes for some sites to do upgrades. The IO-Socket pm is just fine for amavisd on an IPv4-only host.
