Emails from Zoho Books (sender.zohobooks.com) silently rejected - not delivered to inbox, spam, or trash
I am not receiving emails from message-service@sender.zohobooks.com (British Oak Montessori school invoices). The same emails are sent to both me and my wife - she receives them but they never arrive in my Yahoo inbox, spam folder, or trash. The sender is in my contacts and is not blocked. This has happened multiple times. Historical emails from the same sender were delivered fine in 2024-2025 but recent ones in May 2026 are being silently rejected. Please investigate why Yahoo is blocking legitimate transactional emails from Zoho Books for my account rfaee2002@yahoo.com.
