I use it as a sync tool for each new mail I receive. My domain provider offers to me a very small mailbox. Enough for a couple of mails but way too small to use as an IMAP server. So I run a dovecot IMAP server on my RPI and trigger for each new mail imapsync to copy mails over to my dovecot and delete mails on my small mailbox. Works like a charm and allows me to have a virtually infinite sized mailbox for very little money. Plus, all my mails are in my home under my control instead of lying on some server somewhere.
