I'm not sure that Multi Server is a suitable solution for servers which have lower than 50 customers on one Plesk server.
- My expectations are Multi Server owner have a couple of Plesk servers with 150-300 domains onboard.
- In this case, Multi Server solves the issue of global configuration and load balancing for all Plesk farm and used as one entry point for all customers.
Do you use a small VPSs as dedicated servers for particular customers?
I think you are making this more complicated than it needs to be using Multi Server. Your solution for a single Plesk server with remote mail should be just that, a single Plesk server with remote mail. Plesk already supports a remote SmarterMail server if you're on Windows, on Linux you're going to have to roll your own for the time being but I think remote mail will come to Plesk Linux soon (as a result of what they are doing in Multi Server).Remember, this is only to have the mail isolated from the webhosting.

re you planning to make it possible what he describes? If yes, what solution will you use?
We certainly are. Our clients HATE Horde. I'm sure it's very capable but taking Windows clients that have used a solid web application like SmarterMail for ten years and telling them they have to use Horde now simply won't fly, even our clients who have always used Horde don't like it.I bet many webhosters running a Plesk Multi-Server linux farm aren't interested in placing a Windows server, just for mail. Take that into account please.
Could you please describe a scenario how do you use small VPSs? Is it servers with installed Plesk and domains, or servers which stores domains w/o installed Plesk? Do you use a small VPSs as dedicated servers for particular customers?
we do not support custom attributes and resellers, so you can't to dedicate a Multi Server service node for a particular customer
But if everything was under one subscription would that "stick" to the one service node? For instance if they have a subscription that allows 50 web sites, Multi Server would not scatter those across service nodes would it?
I'm envisioning a scenario where we could create a new service node, create a subscription on it, and then immediately disable it (not sure of the exact terminology offhand) so Multi Server didn't assign any other subscriptions on that service node.
