IPv4-mapped

[Patrick Domack via amavis-users]

I'm having an issue with 2.8.1 and ubuntu 12.04 with mapped addresses.  
It seems the inet_acl isn't mapping it correctly.

(!)DENIED ACCESS due to INVALID PEER IP ADDRESS::ffff:127.0.0.1:  
lookup_ip_acl (inet_acl): IPv6 address [::ffff:127.0.0.1] contains  
fewer than 8 fields
