Event 1070 POP not redirected to mailbox

[mingtmak]

Using POP3 Connectors in Exchange until filtering service is setup.
This event error came up and was resolved with

http://support.microsoft.com/kb/842293

but during the time I was troubleshooting, where did the mail go? Was it just lost/discarded or did it get moved to another mailbox or folder?

It doesn't seem to be in the "failed messages" folder:
%PROGRAMFILES%\Microsoft Windows Small Business Server\\Networking\POP3\Failed Mail
or
in the "Undeliverable POP3" mailbox destination I specified.

Thanks,
