The problem is that mail_location setting uses ":" as the "sub-setting"
separator. If I changed it, I'd break a huge number of Dovecot
installations. The reason why I chose ":" in the first place was because
I didn't think anyone would really use it in directory names, because
that would also break e.g. $PATH.

I suppose :: could be used to escape a single : character. I might break
a few installations by doing that change, but I could live with that.
