Don't know what's up, I'm absolutely dripping with acid today, being totally incendiary about everything and anything. Not that they don't deserve it (I follow my rules about whining), but I've got a quick draw and a short temper today.
Why isn't there a server-side Bayesian spam filter for IMAP servers, using the \Junk tag that MUAs like Mozilla use? Since I did not leave Mozilla running on my home machine, today I get no filtering (I don't think that the learning is done properly between two Mozilla instances, so I leave it off at the office).
Why can't I edit the Sieve rules of my Cyrus IMAP (which is otherwise generally great) from within Mozilla?
Why does the "Sharing" tab of the folder properties in Mozilla mail/news tell me just the status and the current permissions and doesn't let me change them? How am I supposed to do it exactly? Use that command-line "cyradm" tool or whatever it's called now? Set up some sort of web interface to do it? Eek!
Why isn't there a server-side RSS aggregator that dumps the feed items in IMAP mailboxes, as HTML? Hmm, there probably is one, but if there's one thing I can rely upon, it's that's probably crappy anyway. Why not use something like Sage or the other RSS features of Mozilla? Because it doesn't work well when running it on more than one computer simultaneously (have to keep feed lists and other state in sync).
I'm not asking for the moon here. There are no NP-complete problems in what I listed. This is all easy stuff that no one ever did, quite simply. Possibly because they were too busy thinking about some NP-complete problem...
