    stupid question: what is a blacklist?
  • DrakonblaydeDrakonblayde Member Posts: 542
    Email blacklist for smtp servers, so they'll reject users, domains, or ip's outright instead of wasting time processing a message

    Personally, I've found forcing remote clients to be RFC compliant to cut down on ALOT of spam, but I'm not sure you can do that with Exchange. Postfix owns.

    I'm using the following:

    bl.spamcop.net
    list.dsbl.org
    relays.ordb.org
    I also completely blocked the country of Germany. ha..

    Very smart... .US and .CN are way bigger spam sources...

    I am using
    http://relays.visi.com <
    I think it might have shutdown?

    The only real problem I had was from Germany sending German links. Once I blocked Germany, Spam was down 99%.

    Definitely dead.

    That's the infamous Sober virus. I noticed that many viruses send the receivers IP address in the HELO command.

    Example:
    SMTP-Server = 1.2.3.4
    Infected-Host = 5.6.7.8

    Infected-Host sends HELO 1.2.3.4 which is definitely incorrect. I have successfully blocked lots of Spam by filtering out clients that send specific HELO names (my IP, my domain, localhost) and this does far less colleteral damage then just filtering a whole country.

    P.S.: My MTA is qmail.

    Nice feedback. That makes sense..I was getting so frustrated with the spam....I will see what information I can find (it was a while ago) & unblock Germany. I figured that blacklist was down. Do you know what happened? I use Exchange; qmail is without a doubt better. I do not have much experience with qmail or thats what I would run.

    I use Mailwasher, which has three blacklists...I know one is Spamcop...works pretty well, lets me see the spam titles before I delete them in case of an error, and sorts out by friend, normal, or B-listed....
    i remain, he who remains to be....
