Hi Tanya,
Please work with me, as I can confirm the following settings with you:

Not a Domain member (can't on the Internet)
Valid Host name AND domain name in the DNS settings.
DNS setting is set for:
host name: mail
domain name: kookiejar.net
IP: 209.205.25.141
RDNS: mail.kookiejar.net.

yes, done.

Yes, done.

here we've got some differences:
I have changed Allow remote VIEW, and Auto deny possible hack attempts

Not that it's particularly funny, but after the above minor changes, the
problem is still 100% reproduceable.
