Same suggestion as Tim Knapp: COREBlog. I'm using it since January and it works just fine. Plus it's 100% Zope, so you can hack any missing features in yourself. The code is quite good (IMHO), I managed to make small patches and amendmends fast, most of it does not have to be done on the file system, as there is a templating system.
COREBlog fulfills all your feature requests: It supports GUI clients, but also posting via mail, and has a usefull web interface. Security/access is handled by Zope, which will make it very flexible. It's Zope, so you will be familiar with securing and hosting it, data is stored in the ZODB, it's obviously non-MS. There is a search tool (simple, but you could beef it up) and you can categorise items to make them easy to find. I <a href="http://betabug.ch/blogs/ch-athens/167">patched my coreblog to let entries with subcategories show up</a> in that category too.
Be sure to let us hear of your experiences. I'll be setting up another zwiki for shared administration of a computer club server soon. So I'd be really interested to hear if a weblog works better.
