Hi,
Check if your sender domain or IP is listed on Spamhaus. Ask them to send a blank email to see whether you can receive it or not - perhaps they include an attachment, characters or other elements that may cause the rejection of their email.

hey
I have the same problem and with multiple providers
Error: “553 5.7.2 [TSS09] All messages from 79.99.28.252 will be permanently deferred; Retrying will NOT succeed. See https://senders.yahooinc.com/smtp-error-codes/” while connected from jesepe.uneafuseauean.xyz (79.99.28.252) to mta5.am0.yahoodns.net (67.195.204.74)
I tried every method / solution and best practices and nothing works !!
so if anyone have the same problem or have the solution ill be appreciate
If you have the same problem with multiple providers, either your IP or domain is listed in a spam database. You can check with Spamhaus to see if this is the case and eventually what to do to get removed from the database.
