A collaborative spam filter

Spammers user thousands of computers to send spam mails, why should not thousands of users collaborate to combat spam more effectively?  That's the major idea behind the collaborative spam filter that BullGuard has created.

The filter learns not only from your input, but also from community input which in turn improves the spam detection capabilities of the application.

It's like the system that is used by WordPress plugins like Spam Karma or Akismet. They have their own spam filters that filter out spam but also access blacklists and whitelists on the Internet that are created by a lot of users.

Bullgard Spamfilter integrates with Microsoft Outlook, Outlook Express and Thunderbird and requires a user account which can be created during setup (just enter a email address and password).

A huge advantage over tools like Spamihilator is the fact that you do not need to change the account settings, e.g. the mail server, in the email client that you are using, it works right out of the box.

One aspect that I personally do not like is that Bullguard adds a footer message to all mails that are sent from your account, saying:

I use BullGuard Spamfilter to keep my inbox clean.
It is completely free: www.bullguard.com/freespamfilter

This can't be unchecked in this version and is definitely a reason for me personally not to use it.

Update: BullGuard Spamfilter is no longer available as a free version. If you are looking for a free anti-spam software, check Spamihilator which we have linked above.

Update 2: And it is back as a free version that you can download from the official project website. The current version is BullGuard Spamfilter 10. You can download the latest version for all recent versions of Windows from the homepage.

Update 3: The product is no longer available separately. It appears to have been integrated into several commercial BullGuard applications such as BullGuard Premium Protection or BullGuard Internet Security.

    You said that Outlook isn’t your main email client, so which is your main one?

    If this is the same bug that I’ve encountered, there may be another fix: (1) hover over open Outlook item in Taskbar, cursor up to hover over Outlook window item, and right-click; (2) this should give you Restore / Move / Size / Minimize / Maximize — choose Move or Size; (3) use your cursor keys, going arbitrarily N/S/E/W, to try to move or size the Outlook window back into view. Basically, the app behaves as though it were open in a 0x0 window, or at a location that’s offscreen, and this will frequently work to resize and/or move the window. Don’t forget to close while resized/moved, so that Outlook remembers the size/position for next time.

    Thanks a lot. I was facing this issue from past 3 week. I tried everything but no resolution. The issue was happening intermittently and mainly when I was changing the display of screen ( as i use 2 monitors). The only option i had was to do system restore. But thanks to you.

    Great tip. Thank you!!!! If it helps, I had to use the Control Key and the arrow keys at the same time to bring my window back into view. Worked like a charm.
