I tried (and failed) to get my postfix relaying in my local IPv6
network.


| mynetworks = 127.0.0.0/8, 192.168.0.0/24, [IPv6:3ffe:bc0:10ab:1::]/48

When I try to relay (excuse me for long lines):

,----

I run a backported postfix from http://www.backports.org/

Postfix works - as far as my tests worked out til now - quite good
with IPv6; mails to "mydestination" are delivered. 


The syntax for the "mynetworks" is taken from
http://6net.iif.hu/fom-servee/cache/18.html and I already tried some
variations which caused the smpd to throttle.

Do I need a special patched version of Postfix to allow relaying for
IPv6 address space?



TIA,
