E-mail delay problems

Hello, We are experiencing some delay problems with inbound e-mails. Some e-mails are getting the status "QUEUED FOR DELIVERY" and showing the event "Delivery Failed DSN code: 4.0.0".
Some e-mails are taking up to 30 minutes to be delivered.

  • Hoep this is fixed by now? 

    Central is showing the typical SMTP errors. 

    Seems like your Email Server is bouncing Central Email attempts (SMTP 400)
