• Our team is looking to connect with folks who use email services provided by Plesk, or a premium service. If you'd like to be part of the discovery process and share your experiences, we invite you to complete this short screening survey. If your responses match the persona we are looking for, you'll receive a link to schedule a call at your convenience. We look forward to hearing from you!
  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Issue Emails sent to host rejected (550)

Hi. All emails sent to my host managed by plesk suddenly are rejected. This is a sample message

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain tropicinvoice.com by mail.tropicinvoice.com. [138.128.173.42].

The error that the other server returned was:
550 This mail server requires authentication (1) when attempting to send via this SMTP (submission) port.

--------------
This happens with every mail provider I try today. Was working fine. I didnt touch anything.
