use Plesk as Backup MX server
Please allow usage of Plesk Onyx (postfix) as Backup MX server
at the moment it is not possible to configure Plesk Onyx as Backup MX server, so even I have multiple Plesk servers available, when main production server is down, all e-mails in that time-frame is lost :((
if we could setup Plesk as Backup MX server, that would give us some redundancy so e-mail should be fine on backup mx server, until primary mx comes back online
