I was a bit in a hurry before and forgot to mention alternative addresses where you can reach me. You can reach me both through my address at work (@sil.at) and through my alternative email address on my own domain (@gwendoline.at) — those go to different mailboxes and thus don't have the problem my Debian and ist.org address (and the various forwards to there, like all the @alfie.ist.org addresses) are encountering currently. I will add the gwendoline address eventually to my gnupg key as a hint for future problems.
Sorry, pals. Yes, I know, my mails are blocked currently. Unfortunately there is nothing I can do about it currently. Usually I have sudo access on the host and am able to fix the problems on my own, but this time its differently: The server moved to a different hardware architecture and thus some things were harder to setup for the main admin of the host. Unfortunately I have found out about the mail server breakage after me phoning him — and now it's too late to phone him tonight. I will try to get back with him as soon as possible tomorrow and hope that I'm not unsubscribed automagically from too many lists in the meantime.
