Hello Rays,
One base question,
Are you going to check the vendor email address manually before saving the PO?
The vendor address in the puchase order is copied from the vendor master so you can maintain email address (single or multiple) in the vendor master before creating the purchase order. At the time of purchase order creation/save, you can change the default email address and use this to trigger PO to vendor.
By the way, user exit EXIT_SAPMM06E_012  (Check Customer-Specific Data Before Saving) is used for custom field not for SAP std field.
Hope this helps.
