Jerry,
Thank you, Thank you, Thank you and Thank you again.
For some reason, I forgot to configure the Internal DNS Server to Forwarder
and the Open All. Once I did that after reading what you stated, guess what,
all my emails started coming in.
Thanks to all for your help.
Anyway, I love TMG. Long live TMG and the new features for Exchange Server
Tee
