- Plesk Onyx for Windows
What are the requirements for using remote SmarterMail server in Plesk Onyx?
Only SmarterMail 15 and later versions are supported.
Mail data from a remote SmarterMail server is not included in Plesk backups. You must put a backup/restore scheme in place manually - for example, following the practices recommended by SmarterTools.
After switching to a remote SmarterMail server, some mail-related functionality and settings, such as spam filtering, antivirus, autoresponders, or black/white lists can no longer be managed from Plesk and must be configured on the SmarterMail side. Note that the functionality is not lost - just replaced by the SmarterMail counterparts.
