Mail server add-on for ReadyNAS?

My ISP already handles spam filtering adequately enough, unfortunately they only offer POP3. What I want is a simple service running on the NAS that will download and upload email from the ISP POP3 server and in return offer an IMAP service that I can connect to both locally and remotely (usually my phone). Yes of course there is a security risk but I think it can be properly managed - I've been running Apache on port 80 on my network for the last 6+ years and I'm confident additional services can be added without the sky falling in. :)

Understood. Not sure if these SMTP plugins offer SSL login options, but if they do make sure your IMAP uses SSL connections.

Are you aware that your headers will not be parsed properly when going POP -> POP server? The mail envelope is opened by the first SMTP server that receives the mail which in this case is your ISP. It can work, but isn't the best way to do it.
