All of a sudden emails from one domain stopped registering and were bringing up the password/username confirm box.
Other email accounts are still working but all email accounts from this particular domain have stopped.
I went home and tried to set up the accounts and they worked.
The email accounts are not from the ISP so im not sure how they could have blocked the accounts, the network also has no server and is set up just like a home network.
Apparently they were having a spam problem prior to this happening.
