    Stuck with "Misdirected Bounces"

    If an email is sent to our mail server and the email address is: invalid: it will not bounce, but cause an SMTP connection error (as it should) over quota: it will not bounce, but cause an SMTP connection error (as it should) We don't have a "disabled" setting on our server - it either exists or it doesn't. The ONLY time I know of our mail server creating a bounce message like the one SpamCop sent me is when someone on OUR server sends OUT a message from our server to an invalid email account on another server (like an invalid yahoo account). But since the only mail sent from our server MUST have a return address that is also on our server, I don't see how a SpamCop trap could ever receive it. Obviously I'm missing something - having the extra information on the bounce email would be helpful as well.

    I don't know, as the SpamCop deputies gave me a truncated message - the part that explains the reason for the bounce wasn't included. However, I have configured uquotachk, which checks for the over-quota limit. What I still can't figure out is why a bounce message from my server would EVER go to a SpamCop trap. The only thing I could think of what what I mentioned earlier, which is clearly incorrect.

    turetzsr, Trust me, I'll ban anyone I find doing something like that. However, I was just blacklisted again, so my suspicions were not correct. Back to the drawing board...

    I appreciate everyone's help here. I think I might have figured out the issue. From the email that SpamCop received in their spam Trap, it appears that it is just a standard bounce. Here is what I suspect is happening: (1) A valid user on our server is sending an email with a "from" address that is a SpamCop trap. (2) Some of the emails being sent are bounced, and Qmail sends the bounce to the SpamCop trap (because it was the "from" address). Thus, the problem is allowing (1) to occur; i.e. allowing a user to set a "from" address that is different than their actual account with us (yes, we do require SMTPAuth, but that doesn't force the "from" address). So I have reconfigured Qmail to only allow emails to be sent that have a "from" domain that is valid for our server. Since I have done this, we have not been blacklisted for over 30 hours, which is the longest we have gone for a while. I am hoping that this is the solution.

    Thank you, but I did look at that. The FAQ specifically says: I have applied spamcontrol. It also says: I have applied the chkuser patch (it is a very useful patch). As I read the FAQ, this should take care of the problem, but obviously doesn't in my case. If I'm missing something obvious, I'm happy to claim stupidity and fix it, but I just don't see anything else I can do.

    Stuck with "Misdirected Bounces"

    Hello, I contacted the deputies, and here was their response: However, I'm confused as to what I can do at this point. Here is how I understand what is happening: This is the standard bounce message that Qmail sends when a sent email can't be received. So it looks to me that a SpamCop trap address is being used somewhere and then the mail bounces to it. My assumption is that someone (on my server?) is faking that address and thus the bounce is going to SC. Is this correct? If so, I really want to correct that problem, but I'm unsure how to proceed. Is it just a matter of finding who is faking the address (an almost impossible task, it seems), or can Qmail be configured to know that the address is faked, and thus don't bounce back to the faked address? Like I said earlier, I've reviewed the FAQ, specifically about Qmail, to see what I can do to patch and correct the problem, but I didn't see anything that can prevent the above from happening. Am I missing something? I will continue to investigate on my own, but any direction would be appreciated.

    Steven, I said: Then you said: I'm not sure where the "80.77.113.30" IP came from, but it is not on our network. My mail server IP is 209.183.220.8. Could you tell me anything about that one? Thank you again for your help.

    Steven, Thank you for your response. The IP in question is 209.183.220.8. Francis
  9. Hello, I manage a Qmail mail server for a virtual hosting business, and over the last month, I have been blacklisted a number of times. The message is the following: * System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop) * It appears this listing is caused by misdirected bounces. We have a FAQ which covers this topic: Why auto-responses are bad (Misdirected bounces). Please read this FAQ and heed the advice contained in it. Since I first got blacklisted, I have done a number on things to help prevent this. I have: 1) Disabled ALL autoresponders on our mail server. 2) Confirmed chkuser is running correctly (this is suggested in the FAQ for Qmail servers). 3) Confirmed that the spamcontrol patch is up and running correctly (also suggested in the FAQ). 4) Went through our mail logs with a fine-toothed comb to confirm no spammers had slipped on past my notice. Nothing unusual was found. However, I still keep getting blacklisted for the above reasons. Is there anything else I can do? I'm simply out of ideas, as I've followed the SpamCop FAQ and nothing seems to be getting me off. Thanks! Francis
