Specs for mail server
I have been interested in setting up a mail server since Google discontinued its free 10 user apps account. I noticed Semoweb is having a promo for a 10TB bw VPS. How many users could I support with 512MB of RAM (burst to 768mb)? I also have a VPS with 1024mb of RAM with 1TB of bw. Would the later be a better balance of mem and bw? I understand there are variables, but which would be the better VPS to get started with?
