WHen I forward or reply to an email I get this from the "System
Administrator" It comes back very fast and so I suspect its a setting on my
computer. I am running Office XP. Pop Email accounts. I recieve and send new
emails without a problem.

It means that you are trying to send through a SMTP server that you have not logged onto. YOu need to set authentication for that server.

I had this same error after configuring my Pop3 account via outlook. Turns out it was a user account configuration problem. To solve this problem I had to do the following in Outlook 2007:

1. Tools -> Account Settings -> Email Tab
2. Open User Name your are trying to send from
3. On Internet Email settings page Select "More Settings"

4. Select Outgoing Tab
5. Ensure the checkbox "Use same settings as incoming server" is checked.
6. Select OK
7. Try the "Test Account Settings" button
8. The "Send test email message" should now check OK
9. Select "Next" and then "Finish"

You should be good to go from here. Log out and back into Outlook and try to send an email.

To whom did you intend to reply? You started a NEW thread. You did
*not* reply to an existing thread. For your reply to be connected

Oh, I see. You're posting through dimenoc.com which is Egghead's
screwed up gateway to Usenet to pretend their forums are bigger than
they really are. If you actually did reply to an existing thread in the
forum then Egghead's gateway is screwed up in not keeping its post
threaded (by use of the References header) to the same discussion in
Usenet on its NNTP servers.
