aq.org is the current target of a huge storm of backscatter spam (i.e., bounces of spam allegedly, but not actually, sent from aq.org), which is bringing the email system to its knees. I've already had to reboot the machine once and do a lot of work diagnosing things. Unfortunately, I’m going to be away from a keyboard for a few hours, and it's possible that the machine (or email on the machine) may go down in the interim.
I’ll do my best to take care of things when I get back home. It’s possible, I’m afraid, that the quickest route to getting it up and running reliably long-term may be to reinstall it on new hardware, so I may be up all night tonight. :-/ Hope not.
[EDIT: After the reboot and a lot of manual unclogging of the tubes, aq.org seems to be doing OK. I still need to prioritize upgrading it.]
