  • Too Many Wannabe-Security Companies

    Interesting what you can discover, just by leaving your server’s mail
    log scrolling in a spare terminal session for a few hours.

    So far this afternoon, I’ve seen connection attempts from two
    different domains, and checking associated websites show they claim to
    be security companies.

    Postfix chucked them off because of “improper pipelining”. That is to
    say, they tried to push through a whole bunch of SMTP commands without
    waiting for corresponding replies. This is not the behaviour of
    legitimate MTAs, and any reputable security company would know that.

    It is, however, the behaviour of quite a lot of cheap-and-nasty
    drive-by spammers. I’m surprised that such can still stay in business,
    unless there are still a lot of MTAs out there which are either
    obsolete crap or poorly configured, that will happily accept their
    spam.

    All nonsense in my logs are practically from those "security" scanners.
    Most of them are obviously from "reputable" companies like Nokia and
    similar scammers.
