We've had a pretty bad server crash.
So... our hosting provider tried to upgrade the virtualization platform that mail.akropolys.com uses managed to crash the entire system and corrupt the filesystem that our virtual machine was using. This resulted in many files and directories being completely lost (in truth, they may still be there, but they're unconnected and there's no good way to know where to "reconnect" them).
I've tried to reconfigure things and get stuff up and running but the reality is that it's more than likely that I've missed something. Please feel free to e-mail me if there is anything that doesn't seem to be working correctly for you right now.
