WisTex Posted April 28, 2005 Share Posted April 28, 2005 True. I can't control what other ISPs do and can't control renegade spammers, but I can control how I get my e-mail and what ISP I chose. I actually don't send e-mail through my ISP. I instead send most of it through my web server with dedicated IP addresses. Since I don't spam and have dedicated addresses, I know I won't be blocked because someone from my ISP spammed. Its a very expensive way to insure you get all your e-mail and a very expensive way to send e-mail, but it beats being lumped in with spammers and irresponsible parties. I don't know how many people would be willing to pay hundreds of dollars a month for a server like we do. Most are at the mercy of their ISPs policies. We are lucky enough to have our own web/e-mail servers and have full control. Link to comment Share on other sites More sharing options...
Wazoo Posted April 29, 2005 Share Posted April 29, 2005 From the newsgroups; Mr. Smith wrote: I agree it probably has nothing to do with Yahoo. But what is strange is these are each a very narrow-interest group with which I have no connection whatsoever (expatriates from a particular province in India, etc). I can't imagine a group-owner trying to randomly recruit members, and these are two quite different groups (the other is something to do with Burma). I did get a third notice from Yahoo groups saying that my request to "unsubscribe" had been rejected because it did not come from my own email address. A copy of the unsubscribe request was included and the IP address traced back to a Shaw cable modem in Canada. This is my only clue as to the origins of these requests (everything else comes directly from Yahoo with no other clues). So someone is screwing around, I am just curious as to the motive, and if it is some new spam twist? If no one else has seen this, probably not. and in another thread; Mr. Smith wrote: > A "message" just got bounced back to me as rejected. Within the message is a > Netsky virus. This looks like an attempt to spread a virus via Yahoo Groups. > I assume my address got picked up from some spammers list or Outlook address > book. It might be even simpler from that. Netsky seems to send to addresses harvested from various files, including archived email and cached web pages; it doesn't use such sources only for spoofing the from address. Anyone with Yahoo group messages on their system will have the unsubscribe address in their archive. Some groups are configured to also include the subscribe address at the bottom of each message, or the subscribe address is likely to be in the browser cache if the user has recently visited the group's home page. -- Daniel W.

Wazoo Posted April 29, 2005 Share Posted April 29, 2005 And from within this Forum structure, an e-mail server administrator takes some action to keep his users happy, configuring a whitelisting for Yahoo!Group e-mail .. results may not please everyone, but the point is that action can be taken by an active ISP.

dbiel Posted September 12, 2005 Share Posted September 12, 2005 Unfortunately, this is one of the sad side effects of the spam problem. The only effective way to block spam is at the IP address it is being sent from or through. There is way too much spam being sent through Yahoo groups and as a result their varrious IP addresses are being added (and removed) from the SpamCop BL frequently. The Receipient can use a white list (if it is available to him) to receive "blocked" mail. Secondly, SpamCop does not recommend/approve the use of its BL as a blocking list, but rather have stated that it should be used as a filtering list; but it remains the choice of the reciepient (ISP or end user) to decide exactly how the list will be used.

Sadly, Yahoo! don't appear to provide a mechanism for preventing spammers from using their system to send junk which means that their servers will often be listed and then the listing is removed once the spew stops. You can, of course, read messages to a Yahoo! group through their web interface. Andrew Link to comment Share on other sites More sharing options...

LizardCop Posted January 15, 2006 Share Posted January 15, 2006 I belong to a number of groups on yahoogroups. I use multiple addresses for these groups. I have my own domain name (lizardcop.com) Some of these addresses are through lizardcop.com. My problem is not that my domain is being blocked, but that certain yahoogroups mail is being blocked to certain addresses. Here is what yahoogroups said they received; Remote host said: 553 5.3.0 Mail from 216.155.201.62 Email blocked using spamcop - see <http://spamcop.net/bl.shtml> Response Code: RBLSC [MAIL_FROM] That was only for one of my addresses in use at Yahoogroups, all the others were sent through to me without a problem. This isn't a situation where ALL of yahoogroups is being blocked to my ISP, only those messages sent to one specific address of mine. HELP!!!

Wazoo Posted January 16, 2006 Share Posted January 16, 2006 I guess what annoys me the most is that it is only the one address that gets "zapped". Applying ancient history, having to make some guesses as to the possibility of having anything to do with any of this ... years back, when Microsoft was busy screwing up HotMail, they ran into issues of (database) servers dropping out .. the impact being for example that users with account names that started with "de" through "fa" were not found in the login process, as the server that held all those user account data sets was "gone" ..... Turning that around, perhaps Yahoo is doing a bit of "load-balancing" and the e-mail output server being used is dependent on your Yahoo account name (and even then possibly rotated some more over a 'set of servers' ... possibly feeding into your accusation of "only one name/account" .. when if you're actually talking about any SpamCop.net involvement, it would only be dealing with an IP address, end of story. And, of course, once "spamcop" blocks the e-mail, it gets sent back to yahoogroups as a "hard bounce" and that address is blocked until I manually reactivate it. SpamCop.net does not have the power to "block" anything, much less send out a bounce ... any and all of this occurred based on configurations set at the "receiving" ISP. The SpamCopDNSBL Blocking List has its own section in the SpamCop FAQ found here (see the top of this page) ... I have no accounts using spamcop, which is another frustrating thing... No one has "an account using spamcop" beyond those folks that have opted to sign up for and use a SpamCop filtered e-mal account. On the other hand, some folks use third-party tools to handle their incoming e-mail with products that use some of the SpamCop.net resources and data. Once again, there is a FAQ here, and there's even a bold link on the Forum entry page that if followed would have taken you to What is SpamCop?

I agree that it sounds that way. However, as Wazoo points out 'using' and 'by' are different. I agree, there are a large number of forums on yahoogroups that should be trashed, but I do not belong to any of those and do not plan on joining. The definition of spam depends on conSent not conTent. As long as the trashy forums are not sending out unsolicited email, they are not involved in spamming. However, even a group that is positively saintly would be spamming if they sent unsolicited email. Like many others, I may go for long periods of time without and problems and then all of a sudden I'll get a number of problems in a short period of time, like right now where I've had the account locked twice in the past 18 hours... For the forums I am just a member of, it's not a big problem. For the forums I own or moderate, it not only blocks the forum mail, but the moderator mail as well. That becomes a problem... Yes, I can see it is a problem. I don't understand the yahoo group structure, yahoo servers, etc., but essentially if you are positive that you are not allowing unsolicited email being sent (by not confirming that the email address that is signed up belongs to the person who signed up), then it is because yahoo is allowing other groups or individuals to send unsolicited email. Your problem is with yahoo. I guess my biggest question is how does spamcop get involved in my mail in the first place? Especially when my ISP is set to NOT report anything to anyone... 39330[/snapback] The only way spamcop gets involved is by the receiving ISP who is 'using' the spamcop blocklist. It has nothing to do with reporting (though those who use the scbl often do contribute to it by reporting). If you don't want your email lumped in with spam email, then you will have to do something about the 'sending' end. Asking people to receive anything from that IP address in order to receive email from you is asking them to receive spam while that IP address is on the scbl.

LizardCop Posted January 19, 2006 Share Posted January 19, 2006 You folks are right, I really don't understand this. All I do know is that at least once a day for the past 6 days I have had to go to yahoogroups and reactivate the one e-mail address because mail to that address from yahoogroups was hardbounced back to yahoogroups by whatever method it's done as a result of spamcop. Thanks for your information and I will go back and read everything again. What I have learned is that yahoogroups ain't changing and this problem is going to get worse until I can find some way to get my mail from them without going through all this filtering.

Telarin Posted January 19, 2006 Share Posted January 19, 2006 Ok, here is how the SCBL and email in general works as concerned with Yahoo groups. Someone posts a message to Yahoo groups. The Yahoo servers generate an email to everyone subscribed to that group with the content of the message. Those email are routed through a series of mail servers (Outgoing Servers) owned by Yahoo groups. Which message goes through which server is probably mostly random, and is designed to balance the load so that all the servers do about the same amount of work. Your particular message gets routed out on a server that happens to be listed on the SCBL. The message in question arrives at the mail server belonging to your ISP (Incoming Server). Your ISP is using the SCBL to help reduce the amount of spam that the process so that they can keep their pricing reasonable. They see that the Outgoing Server that the message came from is listed as a known source of spam, so the bounce the message. Yahoo groups is notorious for allowing group moderators to add any email addresses they want to their lists, and allowing spam to pour forth from the Yahoo Groups servers, so I would not expect this problem to go away anytime soon. However, there are still several possible solutions to your problem: 1) Ask your ISP to whitelist the Yahoo Groups servers so that mail originating from them will bypass the blocklist they are using (SCBL). This is probably the least likely thing to work, as most ISPs will not knowinging whitelist a known source of spam. 2) Read your subscribed Yahoo Groups online. This is probably the best solution, as it is guaranteed to solve your problem. 3) Use usenet or a better service for your groups. There are a number of group providers out there that are more responsive and proactive in preventing abuse of their services than Yahoo. They are less likely to get listed because they actually enforce their policies proactively, rather than waiting for someone to complain before they correct a problem. This may not be feasible for groups where you are not the administrator, but if it is your group, finding a service that can provide reliable email should be a top priority.

btech Posted January 19, 2006 Share Posted January 19, 2006 I don't see what the issue is. You simply need to set up a "whitelist" with "[at]yahoogroups.com" and your messages will come through... unless you run an archaic POP program that doesn't look in the entire header, rather just looks [at] the "from" addy. I had to do this with my Ebay sales notifications, several mailing lists and my own site (because I run spam Assassin at 2, it catches everything)... no problems since then.

Telarin Posted January 20, 2006 Share Posted January 20, 2006 Yeah, whitelisting it in SCMail would work, but I didn't see any indication that this user was using SCMail. I got the distinct impression that they were simply using POP3 to retrieve mail from their ISPs mail servers which by that time have already discarded anything that they have filtered.

LizardCop Posted January 21, 2006 Share Posted January 21, 2006 Thanks Will. Between your explanation and the reading I've done on a couple of other threads, I have a better understanding. I've been working with my ISP. As for the yahoogroups I belong to, I know they aren't the spammers. The ones I own or moderate require approval for all new members and they don't get un-moderated privileges until they post a certain number of message in compliance with the group guidelines. And most all I belong to are the same way. But you can't control everyone. I also understand that it's not SpamCop that's blocking the mail, regardless of what the ISP's or Yahoo say. Too bad the ISP's don't follow the recommendation of SpamCop, that would make things a lot easier. But, regardless of who, I can't fix it so I'll just have to make a work-around somehow. Again, thanks for all the info folks!!! Link to comment Share on other sites More sharing options...
