InBoxer – Email Spam Filter for Outlook

Email Spam

About a year and a half ago I was getting really frustrated with the levels of spam my personal emails were receiving so I wrote a blog post asking what others were doing to reduce their email spam. Someone suggested SpamBayes, a free open source solution, which worked great for a while but then I had some issues with it. This eventually lead me to InBoxer, which is basically a commercial version of SpamBayes.

Over the last year or so it’s been amazing! It uses Bayesian spam filtering, so it took a bit to get it fully going. But once up and running things were great. Unfortunately, last week for some strange reason the database corrupted itself. Who knows why but it was frustrating. My greatest fear was that as I was launching my new EBook I’d be in the middle of training the Bayesian spam filter. I couldn’t ask for worse timing!!! In the middle of promoting the ebook I’d have to look at every single email as the spam filters wouldn’t be trained enough yet.

The good news though is that because of the volume of emails I get I was able to train the spam filter to a good enough level before the ebook launch. It has slowed me down a bit, but not nearly as much as I expected. And it’s reminded me of the appreciation I originally had for InBoxer when I first got it. For $40 it’s well worth it!

    It’s odd how these things slip out of mind. For me, Spam has been a solved problem for a number of years. It must be 2003/4 since I last used an email service that wasn’t GMail based, all my domains that have email are hosted in the Google Apps. I sometimes use Outlook+IMAP to access the GMail backend, but it’s GMail nonetheless. It’s been a while since I’ve seen any spam.

    Hi Tim,

    That’s great news! For me personally, I just can’t find myself hosting my company’s emails on gmail. I can’t explain it, but I just don’t feel comfortable doing it.

    If it was just personal emails, or contracting, I think it would be ok. But for a corporate site I find it difficult… Of course that could just be me 🙂

    In any case, it’s great to hear that spam is no longer an issue for you, and that you’ve found a working solution for you. What a difference it makes!

    Try AntiSpam, a ultra light spam filter

    Created entirely in assembly language (yes, only 88Kb!)

    Protect unlimited number of pop3 email addresses (gmail mail included)

    Scan the mail header AND also a number of lines from the mail body

    Can check all hosts found in the mail header against DNSBL (“Real-time Blackhole List”)

    many other features…


    AntiSpam uses UIDL extensively. This key feature is not present in many spam filters, wich can lead to wrong inbox operations with them!

    Hi John,

    I understand that antispam is built in assembler and takes almost no space, but how is it better than InBoxer? Being smaller and written in assembler doesn’t mean it’s better, just that it’s smaller.
