    Title:
    QQ.com domain SPAM
    Content:

    Our OSvC instance has been inundated with SPAM originating from the qq.com domain. We've had 2,000 unique spam senders with this domain come through in the last 36 hours. They all have the same Chinese text in the subject and no content.

    Is there any way to block an entire domain via Barracuda? I have only found an option to block individual email addresses, which does not help in this case. I know Barracuda is scoring these items, but they all get less than 2.0 on their spam algorithm, so we can't really use the filter to block it.

    I am also curious if anyone else deals with spam from this domain or not.

    Thanks!

    In the Blacklist, it says: "Blocked Email Addresses and Domains (Blocklist)"

    When adding new ones, you can actually enter just the domain name. So instead of entering emailaddress@qq.com just enter qq.com (without the @)

      Thanks Pavol. I was able to discover that shortly after I posted. I'm still curious if other OSvC customers experience SPAM from this domain. All of them were coming into an unpublished bounceback address, so I have no idea how it was found by the spammers.

      I checked ours and we do not have anything from this particular domain, although I know it is one of the big ones in the spam world. I don't think it is worth investing your time how they found you if you can block them this easily :)

      We have faced the same issue with QQ.com domain. We have created a business rule to not create any incident . We will also follow above resolution.

      We've been seeing the same domain for our clients, however adding qq.com to the Barracuda spam filter has not yielded much success in blocking. Has anyone had much luck with the spam filters? I triple checked the mailbox to make sure it's coming in on the expected one but no joy.

        I don't use Barracuda but business rules. It allowes for regular expression matching and then the customer can decide if they want to have incidents just marked with status spam or have the do not create incident in the THEN section.
