EFT Payment Notification to vendors

Hi

User is running Automatic Payment run F110, usually vendors were receiving the payment notification through emails. Recently, the user has run the same, no vendor is received the payment notification. I have checked the email address and vendor master data. Everything is perfect as they are the existing vendors.

Can you suggest me how these emails are linked for notification and what could be the reason for not receiving the payment notification by vendors through emails. How I can correct this issue ?
