Hi. I want to set up a Cyrus IMAPd so that every domain is virtual,
yet still allowing unqualified usernames to log in - in that case, they
should be mapped into some default virtual domain.
This isn't currently possible, is it? I couldn't figure out how,
anyway.. So I thought I'd implement a little something to make it
possible. Being lazy and all, I'd like to do it in a way that you'd be
inclined to commit to the main distribution, so that I can simply use
vendor-provided binaries from the next version on.
So I've hacked together an example patch which seems to work for me,
at least. Comments solicited..
