This is now also becoming a problem because our DNS server appears to have
cached the fact that i can't look up the host smtp01.seinf.abb.se.  This is
causing email to stop going to that host, and in particular one user here
needs to email that host with urgent information.

I can not seem to purge the cache of our current DNS server, and it keeps
returning "Non-existent host/domain" when every other name server I try can
resolve the host name.

What is the normal timeout for a non-existent host entry for named?  It's
been over an hour now sine it's been able to resolve the host!
