• 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.

Server Stopped Acceping Mail for outbound delivery

Basic Pleskian
12 hours ago, mail was working perfectly. Our web app could send all the mail we need it to send, it was delivered nearly instantaneously to its destination. We had just finished installing dkim and spf. Now, mail sent out through round mail is doing perfectly, but mail send from our webapp is not accepted by our own mail server. This server is dedicated to this one app, no other customers.

Here is the setup and the log
