I am routinely getting listed on's blacklist. I've gone through their guide on how to prevent this (lousy guid, btw) and am at a standstill. gave me the best description about it and it looks like my server does the proper notifications for bad emails. I really need to get this taken care of - has been going on for almost a year now and is a thorn in my side. Any advice on how to make sure you don't get listed on (and barracuda for that matter)?
Hello Mooresites,

Any idea which rule of theirs you're triggering or why you keep being blocked? We're just shooting in the dark without that kind of info.

According to, bouncebacks to spammers using your address as a "replyto" should be as follows:

If yourcompany.tld has a properly configured mail server, the SMTP dialog will look like this:

MAIL FROM: victimatvictimdomain.tld[/email (i used 'at' so I could submit this post)
RCPT TO: NoSuchUseratyourcompany.tld
550 User unknown

I tested that from another account outside knownhost and it gave the same result.
Also . . .

I just received a spam that came from my server ( and tracked the originating IP address to Romania. Here are the headers (fyi, is a forwarder of mine).

Thanks for any help!
Got it . . .

Well, thanks to support (you guys truly rock), I found out some of my accounts weren't running spam assassin even though they were just forwarders. I have since activated and all seems to have quieted down. I still have some frozen mail, though not nearly what it was. Thanks guys.
[FONT=&quot]Hi Mooresites, It is good to learn that you got the issue resolved. But can you explain how you got it fixed. I am looking forward to get the solution to this problem. For the first time I am hearing about this issue of getting listed in the blacklist. That’s why I am very curious.[/FONT][FONT=&quot]

It was actually a matter of activating Spam Assassin on each account on my server (I used "send to each users spam box" if that matters). Once all accounts were active with Spam assassin (I use Direct Admin and used "Spam Assassin settings), my queue slimmed up and I was removed from Backscatterer's list . . .
