You mention using bind-8.1.2, but are you sure you're linking exim
against the newer DNS resolver library that comes with BIND-8?
If not then that's likely your problem. The resolver in SunOS-4 is
ancient (approx BIND 4.8.3) and very very buggy. It's the only resolver
I've ever seen give intermittent false negative replies like you report.
I noted the last time I looked at bind-8 that they had not included any
of the tools and instructions from bind-4.9.7 to help SunOS-4
administrators replace the system resolver, including integration into
the shared libc.
