    Blacklisted via Spam Traps

    No, this is certainly not the first time that we have been listed by spamcop, let alone by other blacklists. And yes, I have more than enough experience with how difficult it can be to get off other lists. I am sort of confused by your "Good Job" comment with relation to senderbase however... -Jon

    Blacklisted via Spam Traps

    No, this is pretty much exactly what I was talking about, a message to one of our customers, that they bounced back out through our network. Without direct control of the recipient mail servers, we unfortunaly cannot prevent this from happening in every case. -Jon

    Blacklisted via Spam Traps

    Sorry, I misread a line from the FAQ, thought I saw an OR. I've sent an email to the deputies, thanks for the advise. And yes, we do attempt to get our customers to handle bounces responsibly, but the sad fact of the matter is that a lot of companies have poor IT staff that really don't have any idea how to properly configure their mail servers. Thanks
  4. Hello, I was wondering if I could get some assistance in identifying messages that have hit some spam trap addresses causing our mail servers to be blacklisted. First, some background information. I work for a company that provides spam filtering services to other companies. Part of that service also involves filtering the outbound traffic from customer for content and policy. Over the last few days our servers have started getting listed on spamcop.net. We believe what is happening is that some of our customers are being sent messages with spoofed sender addresses, which we accept and then relay to the customer. The customer will then bounce the message for some reason, which will then be relayed back out through our servers, hit the spam trap and cause the listing. The other possible alternative is that one or more of our customers have virus infected computers which are sending out the messages. The first scenario is more likely as we have tools and reports that we use to detect suspicious outbound traffic spikes from customers and spoofed outbound traffic through our network. The problem that we are having is that without knowing what these spamtrap addresses are, there really is no way for us to pick out which messages are causing the problem and the trace them back to either the customer or the original sending IP address. Below are the listed IP addresses, if a Moderator could contact me with any information regarding the messages that hit the spamtraps, I would really appricieate it. Thanks for your assistance and taking the time to read this. Listed IP address 216.148.222.61 63.161.60.29 12.129.199.61 63.161.60.61 206.16.192.253 217.117.146.230 Jonathan Reichert Network Operations Center Exchange FrontBridge
