False positives on bl.spamcop.net
There was a time when SpamCop’s bl.spamcop.net was a useful blocklist. I say “was” because bl.spamcop.net is getting so many false positives now (several a day, from a variety of unrelated and non-spamming servers) that it has become more of a liability than a service, and I have removed it from my list of blocklists. I now strongly recommend others do the same.
I reported this problem to deputies@spamcop.net, including a sample of a dozen or so of the false positives, a week or so ago. I have received no reply. For reference, here are just a few of the erroneously blocked servers:
- synigent.com
- iconma.com
- ebay.com
- clicknfax.com
- intuit.com
- cardmemberservices.com
- dice.com
SpamCop as a service is a still useful, because it allows me to selectively filter using a variety of blocklists. So I will definitely be keeping my accounts. But I will no longer be using the unreliable bl.spamcop.net blocklist, and therefore there is no reason to take the trouble to “report” spam to SpamCop anymore.
