My mail host (also known as neualius.turzimmer.net) had some fs problems today (==everything was read-only) and fsck&reboot made the thing only worse: The host doesn't respond at the moment. The whole thing will need to wait at least for 10 hours or so before it can be fixed :-/
Luckily, I only store my mail in IMAP there - and synced my laptop a few minutes before the thing broke.
It could be that some mails were lost, please ping me (HE@jabber.org, HE @ IRCNet/OFTC/freenode/GIMPnet) if I don't answer in the next few days.
Nevertheless, I'm busy updating/rewriting the documentation for nm.d.o.
