My latest update in this ongoing saga with Yahoo! Just to recap- 1. Mail server has never been implicated in any undesirable activities 2. Mail server uses DKIM, Domain keys, SFP, valid PTR + A records and current CA issued SSL certificate. 3. Mail server is not listed on any DNSBL as evidenced by dnsbl.info 4. Mail server has no other 'users'. In short totally kosher. Yahoo had previously claimed in writing that what we needed was a privacy policy on our website. So I put one up despite the fact it's totally irrelevant. No one can subscribe to any mailing lists on our website. Actually I don't even do mail outs at present. I wrote back and advised that a Privacy Policy had been posted and gave them the link. I received a cookie cutter style response moving the goalpost to la la land, now claiming they would not tell me what I had to do to get whitelisted and some total nonsense trying to fob off any non delivery problems onto the recipient. This is what they wrote: "This will not result in any kind of permanent block or defer or any other behavior. These filters are solely based off of your mail servers' activity and recipient feedback." I know full well that no one has ever complained or blacklisted any email I sent to them. It is ENTIRELY ONE HUNDRED PERCENT PERSONALLY DIRECTED AND WELCOMED EMAIL. (Sorry for shouting... but I am peeved). In short I claim that their claimed "recipient feedback" in non existant in the case of our MX. And they further stated: "We cannot make exceptions to this rule without mailers going through the whitelist application/questionnaire process. As of now, your mail server is ineligible for this service, so your mailings will continue to be reviewed in this manner." but they refuse to tell me what is required by us to complete their "whitelist" process: "Our apologies, but what specific changes we have made within our systems and what those systems are, how they work, and what they do cannot be disclosed to any 3rd party at this time, as this information is proprietary." In short this is nothing short of disgusting commercial banditry, stand over tactics, and cowboys like this need to be reminded about the ethos and expected behavior of large Internet companies is. I think it's ultimately not paying off for Yahoo because I have been in the industry long enough to recall when Yahoo was the search king and Google didn't exist. My how things have changed. Many of us advertise on Google, optimise our sites for Google and some of us even have Google on our cellular phones (In my case an HTC Magic with Android and Google). I have NEVER had a problem delivering email to Gmail addresses. Clearly "Don't be evil" has struck a chord with Internet users. I will also be cross posting this to other forums and I ask anyone who has been affected by this to contact me off list. Thanks. Michael (Opinions expressed within are entirely my own).
