I want to run a mail server (either Postfix or Exim) solely for redirecting mail aliases.
Its entire function will be to process a table of users for a domain (e.g. springfield-nuclear-environmental-squad.info) that looks like this:
lenny: email@example.com carl: firstname.lastname@example.org smithers: iHeartMrBurns@hotmail.com
However, I'd like a nice web interface for this so that the Springfield Nuclear helpdesk can add people without having to have access to a shell on the server.
The simpler the better; I would rather not have to use a database if possible. I could also knock something up myself in LAMP, but would prefer to use an "off-the-shelf", open source, component, if one exists.
