I have a requirement that I want to archive mails older than say, 6 months to another server, so that I can keep space of first server to be minimum, but still able to access older mails if user requires.
The case is the live server is much expensive. Getting more storage is not a good idea. What I need is keep the latest mails in live server and old mails in less reliable and cheaper server.
Is that possible, if so, how?
