E-mail Bombardment - Blacklist Woes

Posted on 2007-10-16

Having a issue with our e-mail server being bombarded with e-mails. I want to black list them but it seems that whatever is doing it is making up addresses. Looks like it is being a little consistant though and sending e-mails with "jr" or "jq" at the beginning.

We are using ClarkConnect Office 3.2 which allows you to enter addresses to blacklist but I don't want to block all jr and jq addresses. Thoughts?

Sample e-mails: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

    Accepted Solution

    Does it support RBLs?
    I use Spamhaus ( which blocks the vast majority of spam we get. Spamcop ( also works but not quite as well.

    Using the RBLs is the standard way of blocking IP addresses which are known spammers or compromised machines sending spam.

    Our server was not able to keep up to the load. We've installed a new server and everything is working great.
