Hi!
I'm currently running Dovecot 1.1.8 on a HP server using CentOS 5.2 as my IMAP server, receiving mail from postfix, and also using squirrelmail as the frontend.
As I look at upgrading the mail server, I'd like to change to a higher availability configuration (where the server can fail and I don't have to reconfig my imap users).
For the SMTP that's easy, because I can use multiple MX records, and I can redirect a port forward from one server to another. But IMAP doesn't have the same functionality, because it's the storage that matters.
What's the "best" way to do that? Clustered servers using a SAN? NAS? some sort of appliance in front? Suggestions?
Thanks!
Rick
