If someone from the Yahoo mail admin team is on the list, could you please reach out to me privately? We had an issue where our customer SMTP server was turned into an open relay for a short period of time. The issue was resolved a couple of weeks ago, however our customers with Yahoo email addresses are still having our invoices go to their spam folder. Thanks in advance for your assistance. Sam.
