And if the Exim mail-server had tried to deliver a mail to you and
gotten the AAAA record into a local DNS cache? (I've no idea what TTL
you're using, unless it's the same multi-hour TTL on the A record for
psg.com).

It got out too.

I'm on Exim 4.69 (has the PCRE update to the PCRE library that doesn't
have potential security problems, just hopefully not in the way that
Exim uses it); I'm on FreeBSD 6.2-RELEASE-p10, as of the other day,
because of, uhm, the two libc/libutil security holes. *sigh*

All I can suggest is that you make a copy of your Exim config, remove
the isip4 check from that copy, then invoke Exim as:

exim -C checking.conf -bh 2001:4d00:0:e:62:89:13:66

and then try to type the SMTP to send an email to yourself:

EHLO fred.example.org
MAIL FROM:<randy@???>
RCPT TO:<randy@???>
QUIT

The -bh turns on debugging mode; immediately after the RCPT line you
should see debugging output showing what's going on.
