Well I don't know if all that info. from the CGI script has been helpful to
anyone, but I think my problem is solved now. I think I brought the problem
on by recently adding the domain my qmailadmin package is served under into
a round-robin type DNS configuration of two IP addresses. Even though M$
Internet Explorer caches a DNS query internally for some great long time (12
hours I heard) it seems that something else in my internet connection
chain - perhaps my Linux firewall - doesn't, and I'm guessing that's what
tripped the error :

I can successfully perform all functions in qmailadmin since I removed my
qmailadmin domain from round-robin. So my solution will I think be to put it
on a sub-domain on a host which isn't part of the round-robin and whose IP
address won't change, and keep qmailadmin's IP security features.
Thanks for your help once again guys.
David.
