I have a GoDaddy hosting account with a few POP3 e-mail accounts. (This is for personal use.) I want to transition to IMAP - to keep all devices synced. However there is an extra charge for that which I would like to avoid.
So my plan is to setup a server on my network that automatically downloads from the POP3 accounts, stores the e-mails locally, and makes them available via IMAP. I have a DynDns account, so I shouldn't need a static IP.
Is there existing software to do this?
