This morning, I upgraded from 2.8-20100213 to 2.8-20100306 and enabled
IPv6 I have always used the lmtp(8) client to feed messages to
amavisd-new (well, those that picked up by pickup(8), anyways):
pickup fifo n - - 60 1 pickup
-o content_filter=lmtp-amavis:[127.0.0.1]:10026
lmtp-amavis unix - - n - 10 lmtp
-o lmtp_data_done_timeout=1200
-o lmtp_send_xforward_command=yes
-o disable_dns_lookups=yes
I changed main.cf...
mynetworks = 127.0.0.0/8 85.214.20.182/32 85.214.107.53/32
192.168.122.0/24 [::1]/128 [2001:6f8:1048::]/64
inet_protocols = all
smtp_bind_address6 = 2001:6f8:1048::2
...and master.cf:
[2001:6f8:1048::2]:25 inet n - n - 1 postscreen
Now, whenever I try to deliver a mail, Postfix complains liek that:

transport error)
For now, I changed the transport to amavisd-new to smtp(8). Could you
perhaps give me some ideas on how to debug this problem further?
The usual "postconf -n" and master.cf are attached below. And yes, I
know, it's really time for some cleanup with multiple instances ;-)
