Over the last decade all the mail users (well, all but me) are no longer willing to use ssh to login to a terminal session and do things like edit a .procmailrc, but many of them still want server side filtering.
I have +addressing setup, so that helps some, though it is still beyond the abilities of many users and also beyond many websites. But are there any server side filtering setups that I should look at that allow each of my virtual users to configure rules through a relatively simple web UI? -- Sigs are on Summer Holidays.
