This may be a dumb question with an obvious answer:
Does a multi-server install work with the Open Source edition, or only the Network Edition?
The reason I ask is because the Multi-Server Install guide has "NE" in the title, and the comparison list between the products only metions HA/Clustering. I'm not looking for that type of HA/Clustering, just adding some mailbox servers and MTA's to help with traffic and increased mailbox storage space.
Again, I apologize if the answer is obviously pointed out somewhere that I've missed.
