    Pop3 Scanmail

    (I'm not sure this is the correct forum; Moderators feel free to move me ....)

    I use EasyNotification to check for mail every, say, 2 hours. If EasyNotification finds new mail it invokes Scanmail, whose rules help me identify and delete Spam. Then into Mozilla Thunderbird we go ....)
    This afternoon my Pop3 Scanmail looked like this
    <IMG SRC=http://www.chrisgreaves.com/5.jpg>
    The first message is a valid message from a client.
    The remaining 5 have been flagged for deletion
    Good.

    A thought struck me that
    If my client was infected, and
    If I set my EasyNotification to check for mail every, say, 5 minutes, then
    I might be able to ascertain which clients/colleagues/friends were infected by noting that a flood of spam always seemed to accompany an email from the source.

    Comments?
    (Of course I'll also go nuts seeing mail pop up more frequently than every two hours)

    I don't know anything about EasyNotification, but what makes you think that there's a "relationship" between the arrival of a legitimate email from someone and the concurrent arrival of what looks like spam? Couldn't it be purely coincidence that you happen to get these junk mails? I use MailWasher as my front-end and have it set to check mail every 10 minutes. If I were you, I wouldn't hesitate to change my mail checking to a more frequent time setting, but I wouldn't think it's gonna tell you anything.

    I'm supposing that some infections are triggered by someone's use of their email client.
    That being the case, were I infected and began email client activity, the bugaboo would awake and sieze the opportunity to do its work, whatever it is, but a part of which is sending spurious email.

    In the longer term this must certainly be the case. Consider:

    All is right in my world; no spam; no infection; no infected friends. Perfect.
    Then one friend, let's call her Linda, signs up to send me a free greeting card - an email address harvesting scam. Unsurprisingly, within a short while (24 hours?) after receiving the melodious "I love you" greeting card, I start getting spam. Linda's action has triggered a wave of spam to me.

    Now that time interval is too long for me to identify Linda as the source/trigger. After all, I've had another 50 legitimate emails during the 24 hours between receiving the greeting card and receiving a wave of spam.

    This afternoon I was surprised to have practically no spam, and then 5 pop up with the arrival of a single message.
    It proves nothing.
    I was looking to see how much credibility or probability I could put on seeing a wave of spam arrive consistently whenever a specific person sent me a legitimate email message.

    Re: Pop3 Scanmail

    That's an interesting thought I suppose but I don't think I would put much weight into the arrival of one message along with a group of Spam.
    But then again.......?

    I agree. Of itself it is an event beneath our notice. Happens all the time.

    But suppose you were sampling (EasyNotification, Scanmail et al.) mail every 5 minutes and noticed that whenever you received an email from, say, Linda, it was accompanied by half a dozen spam.
    And that Linda, more than any other sender, triggered this pattern.
    Then you'd begin to think that the two events (Linda & spam arrival) were related.

    That made me wonder whether switching to a 5-minute polling might tell me something.

    (A valid response is "Go ahead, Chris, if you have the spare time ...")
    More than anything, I was wondering whether anyone else had noticed packets of spam appearing to accompanying a single email.

    Chris,
    I don't know if I've ever noticed any real pattern except that it does seem to come in groups and then nothing for a while?
    I have my Spam prog set to check for mail every 2 minutes.

    Until a few weeks ago I'd have said that. It seemed that Sunday afternoon was a "good" time, but now, I don't know.
    I'd say it is bound to cluster since even random emissions cluster from time to time, and guided emissions more so. Also determined by the sampling interval.
    In my case every two hours I get lucky and some spam arrives in my mail (grin!)

    >check for mail every 2 minutes.
    Yeah, well, we can't all get contracts with NASA (VBGrin)
