If you’ve sent any email to anyone with a ridey.net address in the past 24 hours or so, it probably bounced back. Sorry about that. But apparently I’m a very lazy system administrator because I got caught out by this bit of geek nastiness.
I think I’ve sorted out the problem now with the help of the good old UNIX command line. Slashdot also has something on this. I imagine I wasn’t the only “lax administrator” who got stung by this. But if you’ve sent me or any other ridey.net address anything lately, please send it again!
