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.

    Thanks. This fixed my issue as my host was set to the hostname with mail. prepended to it.

    Removing the mail prefix allowed the test email to be received in the mailbox.

    The next question is why only the test email can be received.

    Normal emails from outside the website are not received...

    Hello William Brown

    > Normal emails from outside the website are not received...

    I would suggest checking the firewall if port 25 is opened.

    Also, please, check that MX record for the corresponding domain point to the server.

    In case this wouldn't help, consider contacting Plesk Support: https://support.plesk.com/hc/en-us/articles/213608509
