  1. If you're asking for a blacklist to be created automatically from your reported spam, this will never happen. Spammers rarely reuse the same email address, so there is really no point. And, how are you going to manage this data? Over months, we'd end up with millions of email addresses on this "blacklist". Your own blacklist would have thousands of entries (assuming you report spam a lot), pretty much none of which will ever email you again. JT
  2. Thanks for your calm and measured response, Steven. Looking at your account, it appears that we are not able to POP your Yahoo using the old popgate. I see the same error that everyone else was getting. We can login, but not actually retrieve any emails. Do you see any Yahoo mails being POPped? Do you think that it was working a couple of days ago, right before we made the switch? I see that the new system has stopped. We are going to restart it and put in monitoring to make sure it stays running. That is why nobody can connect right now. JT
  3. Yes, we have an implementation very much like the reference implementation. There is a triplet of sender email address, connecting IP address, and recipient email address that we use to make decisions. We are currently using a 30 minute delay for newly discovered triplets. Petzl asked why spam is still getting through and it is simply because the spammers are retrying. For spammers willing to retry, this method doesn't help at all. However, there is evidence that a large number of spammers do not retry. JT
  4. Since all of Yahoo was failing anyway on the old server, we've moved everyone who was trying to POP yahoo over to the new popgate2.cesmail.net server. I haven't heard of any problems so far with our small beta test. We'll be monitoring the new server to make sure it seems to be functioning correctly. JT
  5. And I presume you're getting all of your good mail. This is interesting. I'd like to see more data. If this holds up, there is a possible explanation. Email from new, unknown users forwarded by your ISP will all get greylisted and delayed. Your ISP will retry, of course, so all of this spam will eventually be delivered by us. However, during this time interval all of the blacklists that we use have had time to update. Delaying delivery of your spam by 30-60 minutes might make a real difference in how much the blacklists can catch. If you actually aren't getting the spam at all, either to your inbox or the Held Mail, it might be that a lot of your spam was actually being sent directly to your SpamCop account. Greylisting will help remove a lot of that spam, even if 100% of your legitimate mail is forwarded to us by another ISP. Well, no, see my other post about delaying delivery of spam. This is theoretical. I honestly don't know how much difference it makes. I do know that the SpamCop blacklist is very real-time and new spam sources are often detected within minutes. JT
  6. Most of the usefulness of greylisting comes from email sent directly to your spamcop.net account. If it is forwarded or we POP it for you, greylisting won't help much. JT
  7. As time goes on, I think the majority of users don't ever report their spam, they just want it removed. This removes a lot of spam (and viruses) without relying on particular keywords or blacklists. If you want all your spam, though, you shouldn't enable it. We're going to be working to add some additional information. Greylisting should "just work" though. It's really not intended for you to have to go in and fiddle with. We are working on allowing addresses in your personal whitelist to pass without being delayed. That feature isn't available right now, though. That isn't on our side. That's your mail server losing your email. I'd be very interested in looking in the logs to see what happened. Can you email the address that you were emailing from and to to me at support[at] Thanks JT
  8. You will experience the delay for those, too. The vast majority of users will not notice or even realize that their mail was delayed. However, if it is important to you that all of your email is received instantly after it is sent, greylisting may not be a great option for you. JT
  9. Also, you can now use TLS and there is a correct certificate. So, if you specify TLS on either port, your login and email will be sent encrypted. JT
  10. Helpful hints for users can go here. Specific problems can be emailed to me. Glad it's working for you. For everyone's info, I'm aware that SSL is a little funky right now. It works and encrypts your email, but the certificate is bogus and you might get a warning about that. We'll fix that in time. Jeff
  11. Hi, guys. Want to help beta test a feature before we open it up to the public? We're hoping to introduce outgoing SMTP service for all SpamCop email accounts. If you need SMTP service for roaming or whatever, maybe we can help. First, all the caveats: - This service is beta. It could go away or be unavailable at any time. However, if we accept your email, we'll definitely deliver it. No email will disappear. - Outgoing service is not to be used for high volumes. Please don't put your whole office on it, send to your 1000-user mailing list, etc. It's a privilege, not a right. Any abuse will result in your access being cut off instantly with no warnings. To use it, use the following settings: SMTP server: smtp.cesmail.net SMTP port: 25 (default) or 587 if your ISP blocks port 25 SMTP authentication must be enabled. Use your regular spamcop.net username and password you always use. Please let me know if there are problems. The more information you can provide, the better. Thanks JT
  12. Here is how you setup SpamCop Email with bellsouth.net, a dialup and DSL provider in the southeast US. Bellsouth.net will not forward email from a Bellsouth account, so you have to use the POP method in SpamCop Email. Login to webmail at http://webmail.spamcop.net Click Options Click SpamCop Tools Click Configure external POP servers In there is a list of POP servers from which SpamCop will retrieve email for you. Enter these settings: POP server: mail.bellsouth.net Username: the left-hand side of your bellsouth.net address, i.e. everything before the [at] Password: your bellsouth.net password After you submit this information, SpamCop should start POPping your bellsouth.net account within 20 minutes and pulling all email into SpamCop. Now you just need to configure your email program to POP (retrieve) from SpamCop instead of Bellsouth and you're done. JT
  13. Here are instructions for how to get Earthlink or Mindspring to forward your existing email address to your SpamCop account for filtering. First, go to Earthlink at http://www.earthlink.net Click the "Member Center" icon at the top of the page Click "My Account" near the top Enter your full Earthlink (or Mindspring) email address and password Click Email Maintenance Click Email Forwarding In there, type your spamcop.net address and enable email forwarding. I don't recommend that you check the box to keep a copy at Earthlink. If you do that, your Earthlink account will eventually fill up because you shouldn't be checking mail there any more. That's it. Now change your email program to POP (retrieve) your mail from the SpamCop servers instead of Earthlink and you're done. JT
