    Hi,

    I don't think there is a definitive answer to this question but I'll ask, then explain my situation with a few more questions...

    I'm trying to find an SBL trap in my openers data. I have run it through 2 third-party hygiene scrubs without catching it and know it is in a particular section of my data that I'm narrowing down. I don't want to keep burning IPs, but am close to finding it.

    How long does it take for an SBL to show up?
    Or how many times does an IP/range have to hit the trap before getting listed?

    I know this is subjective, but I'm wondering how many times will I have to mail it for the trap owner to list my range. Or is it a matter of how many days before he checks his mail and decides to list the range? It could show up pretty immediate (happened that way once before I knew where the trap was). But I assume it could also take several days and I don't know when/if I can consider a data segment safe (unless a different segment gets listed to which I would hope and assume the unlisted stays safe).

    Just wondering if anyone has some experience to guesstimate days/drops for a listing to show up.

    Thanks

    If you hit a Spamhaus trap I believe the listing is automatic and doesn't need any manual intervention on their part. It should show up within a couple hours. If you don't see a listing by the next day I'd say you're pretty safe. And you need only hit it once to get listed.

    Send me the list of unique domains in the openers, I will send you a list of domains to suppress. If this solves your problem, send me shiny things.

    All depends on how many spamtraps from the given anti-spam company you got. E.g: Spamcop blacklists you with less than 10 hits to their spamtraps, while Project Honeypot waits for you to hit more or less 50 times, then if you got 10 Project HP spamtraps in your list, after 5 drops you will be banned.

    Spamtraps is very old tactic of spamhaus ,
    They don't operate like this only there are many other factors that can get u SBL in my opinion

    I am 100% certain they rely on traps as the major source for their listings..
    Of course traps are not the only method they use but if you don't hit the traps you're more likely to avoid further scrutiny..

    Ok... so I wanted to follow up again here with a few observations.

    First off, I had 8 /24s I was mailing. Two of the 8 got SBL'd. Strangely I mailed the same data on all 8 of them over a period of time and only the two got listed. Assuming all the mail got delivered on all 8 ranges, I have to believe that SBL's are not automatic.

    I pulled out the last data on the two ranges that got SBL'd hoping the trap was in there (assuming that the listing happened immediately as a result of the trap).

    I split the remaining data into six lists to mail separately on the remaining ranges and mailed away for a week without losing another range. Problem solved? No.

    Since I was losing two of the ranges I decided to see if the trap was in the rest of the data... So I mailed the suspected trap data on those two ranges for about 5 more days - again hoping the SBL would show up immediately on one range or the other. Nope.

    So 6 ranges saw all the data that contained the trap(s) and never got listed. Again, this was data cleaned by two 3rd party hygiene services.

    I replaced those two ranges and started mailing my "good data" again. And I got another SBL on only one range a few days after starting mailing. So there is no way that SBL's are automatic upon hitting a trap or I'd have lost all 8 original ranges and both of the new ranges. Not sure how long I can keep mailing the remaining ranges on the same data and not get a listing. This is really puzzling and even trying to narrow down the problem to a specific data set doesn't seem to be the answer. Apparently whatever trap is out there only checks his email once a month and randomly lists some ranges. And it makes no sense that only one new range and two of the original ranges got hit while all the others did not.
