Server side mail filtering

When you get a lot of mail, and go on vacation, you usually pull in all that mail over your expensive roaming 3G connection. I use filtering to make sure certain mails end up in the right folder. I usually don't want to read all mails that come from mailinglists. You can use filtering from within your mail client  and that works well. That has one huge disadvantage : Your mail client needs to pull in at least...
