The size of server you require will largely depend on how many active mailbox users you will have, storage required for each user, as well as the volume of inbound and outbound mail. We recommend at least 512MB of RAM and 30GB of disk space for a basic email server.
Introducing components like spam and virus filtering tend to introduce higher CPU and memory requirements. A server with 2GB of RAM and 2 CPU cores should provide enough system resources for most personal mail server needs.
ServerMania Hybrid Servers offer the perfect combination of performance and cost to deliver the best private email servers possible.
