[Resolved]Â Mailhost doesn't take into account spam sent via webmail for Yahoo in Mailhost Configuration of your Reporting Account Posted November 26, 2007 You are always welcome to send manual reports or if you are a paid reporter, to add the yahoo address to your outgoing reports. And I do do this. Every email from a valid Yahoo account that I send to SpamCop, I also send to Yahoo. My point is that not everyone does this. The message IS being originated at the Comcast address. That is where Yahoo says it got the message. The intent is not for Comcast to simply "shut down the users email account" but to turn off all internet access to that account. It that example, yes it is. But what is say instead of Comcast it is coming from some block of addresses owned by spammers or say some ISP in some country that doesn't care about spam or say some anonymous proxy server. In that case report from SpamCop goes off into the void while the spammer continues to use the Yahoo Mail account to spam others. I'd say close to 70% of the spam I receive comes from valid Yahoo email addresses, and this is to my Yahoo email address. About 25% comes from Hotmail and the remaining comes from various other places. Yahoo does not do a very good job at preventing outgoing spam. They only close accounts that are used for sending spam. As for hijacked accounts, I'd say if someone is dumb enough to let their account get hijacked and used to mass spam others, then they should be shutdown or at the very least Yahoo should be made aware of it so they can notify the user. In most cases though the spamming accounts are free throwaway accounts created and then discarded. If we can get Yahoo to close them as quickly as possible, it will force the spammers to go elsewhere. Currently though spammers don't seem to have many issues sending spam out from Yahoo. Yahoo is canceling /email addresses/ I don't know how many people have actually checked to see if yahoo cancels addresses, but actually, their 'action' does not have to be cancellation. It could be their action was to read your email and decide to delete it. Also, if it is a spammer, they could be using a new yahoo address every time. They may not care if their old one is deleted after the spam run. I don't know if Yahoo is actually canceling the accounts or not, but I do know that they read the reports since I get a response for every report I send and I've gotten different responses depending on whether or not the headers were forged or genuine or whether Yahoo servers were being used to host the spam web site. In the case where they are genuine the response says they took action against the account in accordance to their terms of service. The TOS states that sending spam through their servers may subject the sender to civil and criminal penalties. You are correct in that the sender can just create a new account, but if enough accounts get closed fast enough it because an annoyance or hindrance to the spammer so he/she will move elsewhere. Also I've found that most spam from Yahoo falls under certain repeatable patterns. If enough people report the spam, Yahoo can block the spam in the first place.
