Customer wants efax set up on Ricoh Aficio MP 2500. Basically faxes are sent out via smtp in the form, <fax-number>@efaxserver.com. So the prefix, the fax number, will change depending on the fax number that the customer send to. Is there any easy was to accomplish this without the customer having to input manually the entire <fax-number>@efaxserver.com address every time? Programming numbers would not work because customer sends out many 1 time faxes frequently.
