Question : Bizhub C350 Scan-to-email

I have a Bizhub C350, that has a scan-to-email function.   The function normally relies on an exchange server to work.  
We have SBS 2003 with Exchange, but Exchange is not setup.  In the past, we weren't necessarily interested in setting up Exchange.  
I setup (about 6 months ago) a port forwarding program (NetworkActiv) to forward mail from the Bizhub to the internet.  
NetworkActiv worked great.    I switched the Hosting and DNS for our main website, which also switched the MX records (to Godaddy).
I reconfigured all the email accounts with little problems.   The port forwarding has stopped working.   It seems like i've tried every last IP and Port setting, but it just won't function.   Any ideas would be very appreciated.  

Answer : Bizhub C350 Scan-to-email

Last time I worked with a Bizhub we configured it to SCAN TO FTP and send documents to a NETWORK SHARE. e.g. ftp://server
This is easier then enabling SCAN TO E-MAIL which requires Exchange with a dedicated account and mailbox. But I'm not sure about the rest.
Regards.
