On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

Emails are not sent from a Plesk server with the errors "25: Connection timed out" and "25: Network is unreachable"

    This solved my issue of emails getting stuck on queue. 

    I'm using DigitalOcean as cloud provider and the Plesk package (https://marketplace.digitalocean.com/apps/plesk), as default on Tools and Settings > Mail Server Settings > Outgoing mail mode, was set to "Send from domain IP addresses".

    I think in my case, as the domains are using a floating IP, the server stop sending emails. I have set the Outgoing mail mode to the droplet IP address and now is working. I have also discovered that I had other messages in queue from the date I have changed to floating IP use.
