SQL Table for Email Address Field Found on Separate Remittance Advice Delivery Tab

Hello - does anyone know what table the email address on supplier Payment Details>Payment Attributes>Separate Remittance Advice Delivery tab can be found?

We have some emails coming back as undeliverable and I'm trying to find an easy way to tie the email address back to the supplier/supplier number in order to correct the email address. The emails that contain the company name are easy enough to find, but we have a few like 'comcast.net', 'aol.com', etc. Thnking I can write a SQL query to query the email address and tie it back to a supplier.
