Fetchmail's pretty easy to set up. Use the fetchmailconf X front-end to create a ~/.fetchmailrc for yourself, which, to run as a system-wide daemon, you will then need to move to /etc/fetchmail. To get fetchmail working as a daemon after you've made your /etc/fetchmailrc, edit /etc/default/fetchmail to make the following changes: SERVICE=true RUNASROOT=true Or leave RUNASROOT=false and set up a fetchmail user account for the daemon to use. I haven't done that yet, though I should (it would help protect my system against any exploits in fetchmail that might be discovered and abused), so I can't tell you if there are any gotchas involved. Then, as root, execute /etc/init.d/fetchmail to start the daemon, and check syslog for errors. > I'm also on a DSL line that is always "up". I think I'd better stick to > using my ISP's smtp server.

Do the best you can with that, then read through /etc/exim/exim.conf and see if you like the options it set.

If mail is sent to an unqualified username (i.e. no @domain specified), exim will try to deliver it to a local account of that name. If the mail is addressed to [EMAIL PROTECTED] (where you is both your local username and your username at your-isp.com), then my guess is that it will probably be routed to your ISP's servers and back to you by default. You should be able to set up a rewrite rule in exim to optimize that, though. I hope all this helps. Feel free to ask for more. Craig
