This post is more for my future reference than anything but if it helps someone out then great.....After much hair pulling with a couple of "techs" we finally got our new Ricoh 2500 setup to only distribute incoming faxes by email and not print them out.
It is a multi-step process that seems to be a lot more complicated than it needs to be. The first step is to get the general smtp and fax settings properly. This can be tested by scanning a document and sending it to an email address. Next set up the email address in the address book for the destination address that you want to send the faxes to. For example fax@somedomain.com. The destination address must be a valid email or distribution list address that can receive email with attachments. The next setting changes are only available in the fax machine, for some reason they are nowhere to be found in the web management interface. The first setting is to enable the forwarding functions. Access it by User Mode/Settings > Fax Features > Forwarding. Highlight the "On" setting then "Ok" Next setup the destination for forwarding, this is the important part. Choose to display destination list and select the destination address that was setup in the previous step. Click "ok" The last steps are to prevent faxes from printing. Go to Fax Parameter Settings and select Electronic Output in the Destination Type Priority option. Finally the parameter setting in the machine itself for "Printing Memory Transfer Files" has to be turned off. Its SW11 option 6. Now all faxes should forward off to email and not print anymore!

Thank you very much for this. I'm going to be trying to get this set up today on a aficio 2018.
I find the Ricohs overall to be quite the powerful and flexible machine. I just wish that they were less cryptic in the configuration. 5 different manuals plus the service guide, plus the desktop binder app, but scan router is you're using that. It ends up being quite the mess one needs to sort through to perform even the simplest adjustments.
Thanks again for your valuable post.
Thanks for the settings.
I have also configured a 3245C printer with the above settings. It's slightly different with the interface menus but the above is a great guideline to go by.
I have tested the receiving fax to email and it works a charm.
Thanks again
