    Unhappy Recipient not authorized, your IP has been found on a block list

    Some of my users are saying that people are telling them that they are getting bouncebacks that say this. I checked the spam filter log, and there are messages from the sender, but it says 'Passed'. What else can I check? I don't use Tarpitting, and the Virus and Phish Blocker don't show it in the log. Here's an example of one of the bouncebacks:




    From: Mail Delivery Subsystem <mailer-daemon@googlemail.com>
    Date: Tue, Sep 6, 2011 at 10:12 PM
    Subject: Delivery Status Notification (Failure)
    To: xxx@xxxxx.com


    Delivery to the following recipient failed permanently:

    youruser@youremail.org

    Technical details of permanent failure:
    Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.7.1 Recipient not authorized, your IP has been found on a block list (state 14).

    Oh yeah, and I have Spam and Phish filters set to Quarantine, not block. I don't use the 'Drop SuperSpam' setting, either, so I don't know why stuff is being blocked at all.

    I doubt this has anything to do with Untangle, that 550 error message isn't coming from Untangle.
    (Untangle will silently accept mail and throw it in the quarantine).

    You can try disabling spam blocker etc for an easy test.

    Thanks! I did a quick search and found that MY server had gotten blacklisted. Boy, am I embarrassed!

    Update: It turns out that I was remotely accessing a user's laptop this morning (she was plugged into the wired network), and I was trying to configure her wireless access. The remote site, apparently, uses a Barracuda Web Filter and it didn't like what I was doing, so it blocked me, and apparently reported me to their blacklist. How nice.

    Just as a quick mail tip, you can check to see if you're on email blacklists (and other helpful tools) at http://mxtoolbox.com/blacklists.aspx

    Very cool site.
