I've been using a spam filter for the last month or so (that could scarcely be news), but it's about the 13th or 14th one I've tried and the first one that I like and feel I can rely on.
So imagine my panic when I returned from a one-day briefing to discover that it had turned itself off and that I had 1183 unfiltered messages in my Inbox.
I managed to re-activate the spam filter (it wanted my registration number), and then asked it (not with a lot of confidence) to filter my mailbox. I hid in a Word file, writing, hoping for magic.
That's what I got. In less than half an hour, when I took a cautious peek at my Inbox, all had been restored to pristine order. I had 203 filtered messages in my Inbox, about 100 messages to be reviewed, and the rest had been dumped into the Blocked file (which I no longer bother reading, since I've discovered that I never find anything I want there). I breathed a deep sigh of relief.
