I have problem. My mail account
info@grey-mores.cz is not recieving forwarded mails from
grey.info@seznam.cz. Seznam.cz support tell me, that error is on Zoho side, because they are recieving error
"552 5.1.1 <info@grey-mores.cz> Mailbox delivery failure policy error".
I have domain seznam.cz and mail grey.info@seznam.cz on whitelists, but still dont wodk.
