Having reshuffled my aliases, I can confidently say that 3/4 of my spam now comes via my from_gentoo_bugzilla alias. (the other 1/4 comes via my from_kde_bug_tracker alias) As I created my account relatively recently and I only use this alias for this one purpose, I can fairly confidently say that there is a leak... which is interfering with my "no more spam" christmas gift to myself. Anyway, let me know if there is anything you need tested. I'm perfectly willing to shuffle my bugzilla-related aliases around willy-nilly.
