Is it just me, or is there less spam...

Discussion in 'NZ Computing' started by Lawrence D'Oliveiro, Nov 12, 2006.

  1. For the past several months, I've been receiving about 200 e-mails a day,
    the vast majority of it being spam. Yet since Monday, this has suddenly
    dried up, and I think I'm now getting less than 50 a day.

    My ISP is Wave, which is part of iHug. They seem to use Ironport to filter
    for spam and viruses. Previously that would mark over 90% of my spam as
    spam, which meant I could run a Perl script to connect to the POP server
    and get rid of everything with "X-Spam-Status: yes" without actually having
    to download it.

    With the reduction in traffic, Ironport only seems to be identifying about
    50% of the spam that is still getting through. Of course, the reduction in
    traffic is _wonderful_, as it makes e-mail worth using again.

    But I'm not so sure I'm impressed with Ironport. I have a couple of other
    e-mail accounts on clients' machines that I set up with Postfix and
    SpamAssassin. and SpamAssassin seems to be catching a higher proportion of
    spam on those accounts. I've seen at least one message so far
    (titled "Thank you for your loan request"), that Ironport doesn't think is
    spam, but SpamAssassin does.

    Thoughts, anyone?

    200 a day? Isn't it time to change your email address when it gets that
    bad? My Yahoo! account, which I've had for about 10 years, is getting
    about 30-40 a day now, which I thought was pretty bad. My work email is
    worse, thanks to my email address being on the company website for a
    while, and also on newsgroups etc where I wasn't too careful about
    hiding it, but even so probably only 50 a day.

    If it ever got to 200 a day I would bin it and get a new email address.

    I've had my hotmail account for 10 years, spam was pretty bad with hotmail
    at the end of the 90s and into the new century. But now I'd be lucky if I
    get 1 spam a week thesedays :)

  4. *Sigh* of course it couldn't last :). I check my e-mail today for the first
    time since Saturday, and there were 965 new messages, of which 958 were
    spam.

    And guess what: not a _single_ one of them was marked as spam by iHug. Not a
    single one.

    This worries me.

    Is there a reason you need to stick with that email address? I would've
    thought the inconvenience of giving everyone your new email would be
    less than dealing with this amount of spam for the rest of time...!

    Or simply use a GMail one, its been MONTHS since i have any spam though
    GMail. The plus side is I can also move ISPs and not have to tell
    everyone my new address.

    I get about 20 per day on my GMail account. That not counting the ones
    that slip through mailing list filters. How long have you had yours?

    Cheers,

    Same here with my Gmail - but 5-10 a day. The filters seem to work
    pretty well, but it is fairly constant.
    Some of my other ISP provided accounts have been hammered over the past
    few weeks.

  9. iHug are still having no luck with their spam filters. This morning there
    were over 1500 new messages since the last time I checked (Friday night).

    I wrote a Python script which connected to their POP server, downloaded
    copies of my messages and fed them through a local copy of SpamAssassin,
    deleting those which were flagged as spam. That caught a few, though not as
    many as I was hoping. So I added a few more rules to my script, mostly
    looking for certain e-mail addresses (some I had entered into Web sites in
    the past, others I had never used), and the combination of all that
    whittled the backlog down to a much more manageable 300-odd.

    Madness! Get a new email address!

  11. I recommend using something that does Beysian filtering. In
    combination with something like SpamAssasin (which I presume blocks
    known bad IP addresses), it should work well once you have trained the
    filter.

  12. SpamAssassin does that, among a whole lot of other things.

    SpamAssassin is highly recommended, except that it can be vulnerable to
    DOS attack.

  14. There are ways to counter that with a DOS of your own

    No point now, with botnets.

  16. That async multithreaded system could probably cope with an entire botnet.

    The scum are getting cleverer, if you look at the images that are being
    sent now, they have multicoloured backgrounds with random splotches of
    colour and wavy letters to fool the image scanners.

  18. I've never noticed, because I never look at spam messages in anything other
    than RFC2822 source form :).

    I've added another Python script to my arsenal. This one rapidly goes
    through the contents of the POP mailbox, showing me a few selected header
    lines from each message, and lets me hit D to delete it. Much quicker than
    actually downloading the message into my MUA and deleting it there.

    Hi,

    I think image spam is here to stay.....cannot see any let up on our MX
    systems filters, so it maybe being filtered a bit better but the
    quantity looks the same....

    regards

    Surely this filter is easy ? If the email contains an image, it's spam ...
    unless you have been told otherwise :)
