Unable to send mail

Hi team,

All outgoing mails are undelivered and returned to me.
I tried sending to Gmail and Hotmail. Both server aren't accepting mail from our server. Can you please look up?

Eg:
This is the mail system at host freemail.byetcluster.com.

  • Some of our IP addresses are currently blacklisted on quite a few blacklists, but we are already working to get this resolved as soon as possible. We're sorry for the inconvenience.

  • Hello, I also can't send any email, I have tried sending to my gmail from my info@[domain].[etc] and it says that an error occurred and it failed to send message.
    I have set the MX records to "mx.freecluster.eu." (proiority 10), but I have also keep the default "mx.[domain].[etc]." (priority 0).

    I also tried to send to another one of my accounts and all went well, but with GMAIL there is no communication (sending or receiving), there were some system messages I got after failing to send my emails though.

    Do you have any idea what that might be?

    The email account I am trying to send the message from is about a day old.

    Thank you,
    Orestes

  • Checked again, I can receive messages from gmail
