Spamhouse is bouncing me again, this time because *they* have a bug (see below). I tried asking Karanbir, but I guess he's not online yet.... Thanks in advance.

I've tried, twice, to suggest that a workaround that doesn't involve a new, and possibly experimental f/s would be to use rsync with hard links, which is what we do. There's no way we have enough disk space for 5 weeks of terabytes of data.... However, the reason I haven't been able to suggest it is that I'm being blocked by spamhost. And when I go there, it asserts I'm listed in the CBL. And when I go *THERE*, it tells me I'm not. Oh, and now, when I try to go to the CBL, it's down. I don't suppose the CentOS list has a whitelist.... mark
