    Cornell's alumni forwarding blacklisted

    Yes, I suppose it's my fault for picking Cornell as my university of choice back in 94, and for being so stupid i should give up my email address and find someone else. I should've known that their email forwarding system will be setup in a way to gets it blacklisted by spamcop regularly. You simply fault me for not understanding why Cornell's system is setup the way it is, and why it fowards email between filtering servers before passing it onto paxio. You fault Cornell for not simply closing some port and making the problem go away. Do you think I WANTED to have my email bounce randomly for 4 months? Yes, it is a nice thing that listings on SCBL goes away, but it's also sh**ty that they black list normal users email just as easily. And they do it repeatedly w/o the option of letting me do anythign about it. If I was allowed to whilelist all of Cornell's servers to be excluded when forwarding email to Paxio, i'd say "spamcop is cool." But that's on the case, and by leaving me powerless, I'm going to claim that spamcop sucks.

    I'm sorry, but I don't see why I should have to put up with months of email blackouts. How would you feel if over the next 30 days, we'll randomly pick 20 days where all email to you gets bounced back to the sender. Perhaps your opinion of spamcop would change as well. And you know what's sad about this? The whole time i'm blacked out, all I got was spam that got sent directly to the paxio account. Either way, yea spam sucks, but my outlook filters it out well enough to catch it. Spamcop should be transparent to the end users, and if it's not, there's no point in supporting a crappy product.

    I got a better solution. I convinced my ISP to drop spamcop. WOOOHOO!! Cornell was held hostage at the mercy of these bastards, and isp came to realize that what's the point of spending money on this service that blocks all email and is useless to customers. Perhaps in the future spamcop will wisen up. FYI: Here's last explanation from Cornell: The way mail relaying works, on any server, is that ALL messages sent to an email address are redirected to a different email address. In your case, anything that comes in for [at]cornell.edu is sent to [at]paxio.net. The only filters we have in place for spam are for messages that are actually delivered to accounts on our mail servers - anyone who receives their mail at their [at]cornell.edu account. There are many universities who are having trouble with SpamCop blocking their forwarded alumni mail as well. Since SpamCop refuses to do anything about this new practice for any of the universities that forward mail to their alumni, a solution we have found to this problem is to stop paying SpamCop for their services because they are preventing alumni from receiving their messages. If all alumni who encounter problems receiving mail because of SpamCop encourage their ISPs to do the same, SpamCop may stop this new practice if they lose enough money because of it. As far as which servers to have paxio whitelist, you should start with the ones that you have already received bounce messages from, since different servers get blocked at different times by SpamCop. You could start with 128.253.83.143 (the one you forwarded us), 132.236.56.56, 132.236.56.28, 132.236.56.31 I believe are the most commonly used ones. If you receive more bounce messages, you could forward those IP addresses to paxio. If you have further questions, please do not hesitate to let us know. Thank you, and have a pleasant day!

    Spamcop doesn't block email directly, but with so many ISP's relying on their list, they can easily kill anyone's email by putting it in their list. And this rally gets to the root of the problem. Why are they blocking my POP3 server? For example, say a gmail user sends me and email. The email goes goes like this: gmail.com -> cornell.edu -> paxio.net Once gmail.com is certified as a valid SMTP server, why would anyone care if the POP3 server at paxio.net is blacklisted or not??? Spamcop's system seems really effective at blocking recepients of email, but I just don't see how that's beneficial? Another question: Based on the example above, who generated the error message? Was it gmail saying "cornell.edu is blacklisted, i'm not sending anything there" or was it paxio saying "cornell.edu is blacklisted, i'm not accepting anything from there'? -martin

    Cornell's alumni forwarding blacklisted

    I looked at it, in the past 7 days, I've seen my ISP's IP blacklisted, and then two different cornell IP's blacklisted. This is getting out of control, as I don't believe that I'm a unlucky user where every email system I use gets blacklisted. What really gets me is this prevents me for RECEIVING email. I can totally understand blacklisting SMTP servers, but what is the point in blocking the receiving path? Suppose, a friend sends me an email from his gmail account. Once spamcop certifies that gmail is a legit service, where's the benefit in bouncing the email at cornell.edu or paxio.net? Certainly blocking pop3 servers, hasn't decreased the number of spams I receive. By request, below are all various forms of bounced email that I've had trouble with in the past month. 1) ---------------------------- -----Original Message----- From: Mail Delivery Subsystem [mailto:MAILER-DAEMON[at]cornell.edu] Sent: Tuesday, November 08, 2005 10:06 PM To: jeremy.friedmaatgmail.com Subject: Returned mail: see transcript for details The original message was received at Tue, 8 Nov 2005 23:06:11 -0500 (EST) from daemon[at]localhost ----- The following addresses had permanent fatal errors ----- mwasiaatpaxio.net (reason: 550 Rejected message because 132.236.56.31 is in a black list at bl.spamcop.net) ----- Transcript of session follows ----- .. while talking to mail.paxio.net.: DATA 550 Rejected message because 132.236.56.31 is in a black list at bl.spamcop.net 550 5.1.1 mwasiaatpaxio.net...

  7. As Cornell alumni, I am able to keep my Alma Mater's ([at]cornell.edu) email address. After graduation however, you need to forward the address to another ISP, and so I chose to forward it my ISP ([at]paxio.net). Last week, I started hearing reports of email bouncing because cornell's server was blacklisted. I contacted Cornell, and got the following reply: -------------- SpamCop recently decided that it was going to start listing the IP address of mail servers that relay mail on its list of IPs that are potentially sending spam. CU On the Net, our mail forwarding service, is a mail relay service. We are not going to stop relaying mail, because that would mean alumni would not have the mail forwarding service available to them. SpamCop is refusing to stop listing us for relaying mail. This means that any ISP that uses SpamCop to check for potential spam is most likely going to end up blocking a person's CU On the Net forwarded mail. -------------- What the heck? Why is SpamCop allowed to effectively nuke my email address. The whole point of forwarding is so I can switch ISP's and still keep the same email address, but SpamCop feels that everyone should either switch email addresses when they move or move to a web-mail based system. Are any other forwarding services blacklisted, or is Cornell's the only one? -martin
