    Outbound email failure for certain recipients

    christian.soverini
      Recipient Disposition: [250 Queue (All MX servers are unavailable for domain securservice.it); Mode: normal; Queued: yes; Frontend TLS: no]
      Detail: first attempt failure: 451 all mx servers are unavailable for domain securservice.it

      For certain suppliers we have problems to send them email. Like the example above.

       

      We can receive without problems.

       

      Is there a fix or workaround?

       

      Thank you
