I was thinking about starting coding again, and went to reset my bugzilla password, but bugzilla's IP is blocked by Spamhaus blacklist... I turned off spamblocking from my e-mail server, so my problem is solved, but I thought I'd let you know about the blacklisting anyway, since other people may not be able to control what kind of spamblocking their e-mail server is doing.
