FYI, upgrading from 2.7.7 to 2.9.2 fixed my problem.

The issue was the way postfix handled the scoping of IPv6 link local
addresses, and the issue was fixed in the 2.8 releases so when I
upgraded to 2.9.2 the problem went away.  In particular, newer versions
strip off the trailing '%eth0' from the link local address, which allows
the rest of the IPv6 address matching code to work properly.  Now the
logs look like:

Jun  4 09:56:23 mail2 postfix/smtpd[17821]: connect from unknown[fe80::224:d7ff:fee7:8924]

... without the %eth0 at the end.

-derek, who wanted the next person to know how to solve the problem.
