FreePOPs is an easily extensible program, which allows access to the most varied resources through the POP3 protocol.
Mainly, it can be used to download mail from the most famous webmails, but it could also be used as an aggregator for RSS feeds and much more.
This way it is possible to get all your messages in your favorite email client
FreePOPs is a POP3 daemon plus a LUA interpreter and some extra libraries for HTTP and HTML parsing. Its main purpose is translating local POP3 requests to remote HTTP actions on the supported web-mails, but it is really more flexible.
For example there is a plugin to read news from a website as if they were mails in a mailbox. You can easily extend FreePOPs on the fly, without even restarting it. You can add a plugin or modify an existing one simply changing the script file since the plugins are written in LUA and are interpreted on the fly.
