See, about that... I use Outlook.

I know that makes me a bad person who deserves to die, but, well, I had a Windows Mobile device for a long time and it kind of becomes, you know, a habit. I tried going cold turkey but the docs said that wasn't the way, and I guess they were right... I'm still using it.

I told myself I could quit anytime, and I did. Seven times.

So there's no way to actually tag something meaningfully as spam in Outlook. I can (and do, regularly) drag things into the Junk Email folder in the IMAP store, but that doesn't (insofar as I can tell from those stats and my own experience) seem to actually mark them as Spam. Of course, if I do it using the Kerio web interface all is merry, but that's just a pain in the bum.

I would drag at least twenty messages a day into the Junk Email folder, methinks, but... where do they go? Is there a "right" way to do this that you know of, or is that as good as it gets?

You could try the Kerio Outlook connector, that will also give you calendar/contacts etc (thus accessible via the webmail client). I haven't used it myself though.

Linky. You'll need to scroll down the page a bit. It is a free download.
