One cause could be using CNAMEs inappropriately. Which brings us
back to the mail.
A brief look suggests these may not be BIND nameservers, if
arwena is running Microsoft DNS, it could be problems with the
zone that are causing zone transfers to fail, the low expire
time would allow the data to expire. BIND typically spits an
error and carries on, Microsoft DNS is less forgiving.
If this is it, it probably shows up in your servers logs as a
lot of repeated zone transfer requests from arwena.
Arwena is definitely answering queries from cache, not from it's
zone file.
Lame is bad as a lame servers get blacklisted, reducing
redundancy. Postfix alas can't be more robust than the DNS, at
least if it can I'm sure Wietse will find out how eventually.
