Hi all. I've been running qmail with great success for many years.
I'm running gentoo with netqmail-1.06-r2; my network uses PowerDNS as
its local DNS server.
I recently upgraded to pdns 4. That's broken my qmail; now all
attempts to send result in the dreaded
CNAME_lookup_failed_temporarily._(#4.4.3)
I've debugged a bit. Netqmail-1.06-r2 includes the big-dns patch, and
I verified that it was applied correctly. I've run wireshark to
capture the network transactions, and nothing looks amiss. I'm
getting valid responses, which are well under the 512-byte UDP limit
(though that shouldn't matter). The problem is clearly pdns, as when
I change my resolver to some other server, qmail is perfectly happy.
What else should I look for? What conditions other than oversize
packets would cause qmail to consistently faile the CNAME lookup?
Thanks in advance...
