Hello,
How can I fix the problem? :/
Good days,


Message is waiting at mail.domain.com for delivery to mx1.domain.com.tr.

Message delivery has been delayed to the following recipients:
Recipient: [SMTP:mail.mail@domain.com.tr]
Reason: :idea: Remote SMTP Server Returned: 451 4.3.2 Please try again

The remote server could be greylisting or have a receive limit. You would need to contact whoever runs the remote server as there is nothing ME can do about that.

Do you have SMTP retries set ? That would get around greylisting by retrying after a temporary failure.
