That looks awesome, thanks. You(?) went a lot further than me (and further than I want to go, admittedly).

Still, for people looking for a more complete package that looks like a much better alternative.

Not for me, because I'm trying to get away with a much smaller machine and less dependencies (i.e. I'm still really unsure if I want a webserver. I decided to go for clucene instead of solr because of the dependencies etc. etc.).

I will follow that repository though and think about recommending that to friends/coworkers though, depending on their needs/expectations.

I have only contributed a little on the project, most of the work has been done by its main author and others.

I'm very suspicious when MySQL finds its way into an open-source package, due to its ties to Oracle. Why not Postgresql?

Why not MariaDB and then you don't have to worry about fixing third party packages that depend on MySQL specific behavior?

Why would an email client need an RDBMS backend in the first place other than the fact that, like WordPress, the devs did not value KIS? Squirrelmail does fine without a db, as do all of the command line clients.

Actually there's an issue open right now to switch to postgresql
