This article aims to describe how to turn the Plesk Mail Service on and off for a specific Domain Alias.
If the service is left on and email is hosted offsite, for example with Google or Office 365, then all emails sent to your Domain Alias from the server will be deliver locally to the server, possibly causing ‘Undeliverable’ error messages.
To address this you just need to turn the local Mail Service off in Plesk.
This article is suitable for Plesk Onyx and Obsidian.
