Holy spam!

August 22, 2008 · 2 Comments

So recently I reworked our spam filtering in the office.  About one month ago we put a Microsoft Small Business Server which has Exchange Mail server, so rather then mail travelling through our web host it now comes directly to the office.

Previously, when the mail went through the web host all the message tagged as spam were deleted before they got to my mailbox.  Now with the Exchange filtering they are coming to my mailbox, but automatically going into my junk mail folder.  We’ve got the filters set quite well, and only very few spam messages are actually ending up in my inbox.

So here it is.  About 2 weeks ago I cleared out the junk mail folder.  Since midnight on August 9th, until now, 3pm on August 22nd my junk mail folder has received:  7620 emails.  Thats a lot of junk.  Lets see, thats 7620 messages divided by about 303 hours, thats about 25 / hour, or about 1 piece of junk every 2.4 minutes.

Thank god for spam filters, there would be a heck of a lot of wasted time without them.

So here’s the thing, among those 7600+ emails, I’ve found 2 valid messages.  Thats not bad I suppose, about 1 in 3500 – 1 per week .. but what if one of those emails was “the big job”.  It sure would be nice to autodump the spam, but I guess I can’t.  Bastards. 

Email has been called “the killer app” .. that is its the application that no one can live without.  Without spam filters, it would be the “the killed app”.  Having to check hundreds of junk message every day for the odd misfiltered email is a p in the a.

If you email, and I don’t reply, try giving me a call.

… since I started this entry, 6 more pieces of spam have come in.

    Simon,

    You are certainly getting more spam than I. I would say my average seems to be about 5% of my email is valid emails either from known people or from newsletters and other sources like Tiger Direct from which I don’t mind receiving info from.

    One solution that I have heard of is one where anyone who is sending an email to you must be validated first. It sounds like a good solution but I have not been brave enough to try it yet myself.

    One thing I have been very strict with is telling the Microsoft Junk Email tool what emails are junk mail. It takes me about 2 minutes each day but it certainly does seem to have helped to keep that ‘crap’ out of my inbox.

    I heard that the City of Toronto system administrators have estimated that about 98% of the email that goes through their network and servers is some kind of spam.

    Would it not be nice if we could just send it back to the originator on a regular basis. I wonder how long they would last?

    Yes, constant maintenance is certainly the key.

    The exchange rules are good, but like anything they are only as good as their last update. Lately I’ve been getting a lot of “greetingcard” type emails in my inbox. I find Outlook’s junk mail filter wants to just block the sender (which seems to be different on every piece of spam), so I generally create a rule along the lines of “if email contains text xxxxxx, move to junk mail”.

    Lately though I’ve run into a limit in the amount of rules Outlook/Exchange allows. I’ve been retiring old ones to make way for the new ones, so far that seems to be ok.

    What I’d like to do, and haven’t looked into it yet to see if it is possible, is share my rules with the other folks in the company: so if I create a rule that says “if email contains text xxxxxx, move to junk mail”, everyone else here also gets that rule.
