It depends on how where you want the email to go. Centralized (easy backups!) or stored on each machine? > In my work place, only my box is Debian which serves as an internal > server and all the others are using Windows System. fetchmail only runs on *ix, so I guess that answers that question. An issue with fetchmail is that the user POP passwords are all stored in a (read protected) plaintext file. Since I only use fetchmail for my family's LAN, it's ok if I know what their POP passwords are. I wouldn't know how to configure a business to use fetchmail and keep passwords private. > Let's say I > installed MOODLE on my PC and my co-workers signed in as a new > user for this application.
