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?
apt-get install fetchmail
should suffice for installation. As for the mail server, I'd then recommend dovecot; I'm running that on my BananaPi and am pretty much pleased: dovecot+postfix+amavis (and some additions), handle the load for 4 domains here, including primary MX. If that sounds interesting for you, let me know and I check my notes at home for a fitting answer; but I'd suggest splitting that for a separate question then (1xfetchmail,1ximap) – Izzy♦ Nov 11 '16 at 13:10
