What about SPF and DKIM in your DNS settings?

Hello, 

In addition to checking your SPF, DKIM, and DMARC records I also suggest that you sign up for this. 

Yahoo's Complaint Feedback Loop (CFL) aids email senders in managing spam complaints to improve their sending reputation. When a user marks an email as spam, it's recorded and could affect the sender's reputation. By joining the CFL program, senders receive forwarded complaints from Yahoo about perceived spam emails from their domain. This program only supports DomainKeys Identified Mail (DKIM)-signed emails. 

Let me know if this helps. 

Thanks, 

Yeah, I've been doing all that stuff for years. Since we migrated, all the settings were copied from the old server and the IP addresses were changed.

Sent email to @gmail.com he headers indicate:

Authentication-Results: mx.google.com;

       dkim=pass

    DKIM-Signature: v=1; a=rsa-sha256;

       spf=pass

have RDNS setup aka pointer

I've been setup for the complaint feedback loop on Yahoo and Microsoft for years, once a week we get a false spam complaint from our Xenforo Forums and I ban those users.

When we migrated from MailEnable to SM, we had to re-fight AT&T/Yahoo as well as Microsoft (even though we are in both feedback loops) because our IP address changed and those providers basically auto-block any new IPs or IPs that come from certain real estate like AWS.

It took two weeks of back and forth before our new IP was cleared and able to send inbound. Every time we have an IP change, this happens. This is even with SPF, DKIM, and DMARC properly configured.

Many hosts arbitrarily block new IPs and make you fight to get them unblocked.

Years ago we had to threaten Microsoft with legal action before we got unblocked - even though our IPs have NEVER been on a list except for one incident almost 20 years ago (before the DNSBLs were really even a thing)...

J. LaDown- AT&T fixed it within hours, haven't heard a peep back from Yahoo using this support form- Here is where I submitted last week-  https://senders.yahooinc.com/contact/

Looks like they are the only problem. I hated to move servers but ours was 5 years old and we were paying 300 per month and now paying 64.00 month for a MUCH FASTER server! 2x Intel Octo-Core E5-2680v2 - 96GB - 240GB SSD + 1TB HDD

Wow, that's a nice server for $64.  Can I ask where?

TIA,

Kevin

Your new IP addresses need to "warm up." Been there before. 

Ron- It's a small business called DediOutlet. Use my affiliate link to sign up to save $$$ https://bit.ly/DediOutlet

The control panel for the server is amazing. Can install pretty much any O/S, reinstall an O/S power on/off the server, reboot it etc. Could not do any of that at Aptum and waited almost an hour for them to power back on a server I inadvertently shut down!

I used Serverbeach, that was bought by Peer1, that was bought by Aptum. They are the big dogs. They keep raising the prices all the time after covid, even on old servers. Also, they charge you monthly for Windows and at this place, they activate a 6 month trial. You can either re-trigger the 6 months on that 5 times, or I bought an activation key online for 30 bucks!

I was paying 300 bucks a month for an old server Windows 2016 Standard Server Intel Xeon E5-2620 v3 @2.4 GHZ with only 32GB ram!

@ActorMike -- If memory serves me correctly, AT&T and Yahoo share some infrastructure -- in the past, resolution with AT&T has provided some relief with Yahoo services.  This may be different now after changes and sales/mergers.

I fought Yahoo once and eventually through email managed to get things resolved.

@RonRaley -- I know about the warm-up periods - but to be honest, with an established company, those should not be a requirement.  That was our argument when fighting Microsoft and AT&T - we had to bring up the fact that we already had established mail service with a clean reputation and their preemptive blocking of IPs without even consulting their own systems where we can identify the IPs we send from.  Our main point was why do you have forms we can fill out if you fail to reference those forms when we start communications with those IPs in question.

I get the real-world scenario - but it's flawed - and the actions by the big providers (who are a major source of spam themselves - especially Google) with unilateral preemptive blocking does nothing but line the pockets of services like SMTP2GO because many providers can't wait weeks to warm up an IP just because of a unilateral block without reason.  Additionally, why should we be forced to outsource our mail delivery just because they can't create a proper system for established providers (especially ones already registered in their networks) to immediately unblock IPs and enable communications...

AT&T may share the same infrastructure with Yahoo, but I contacted AT&T at abuse_rbl@abuse-att.net 

they responded and now emails go through to ATT and Prodigy.

Our only problem now is @Yahoo.com

I will keep bugging them and eventually get off the blacklist I hope!

This is one of the reasons why it would be useful to have SMTP routing rules

I keep suggesting it but I get totally ignored. Not even an explanation as to why SM doesn't consider it something to develop.

Imagine being able to set this rule

If the recipient is @yahoo.com use the following outbound gateway.

You could use smtp2go only for yahoo.com while the new IP gains reputation. With the same logic, other blocks or other specific situations could be resolved.

I agree with Sabatino! That could be a great function to add to add to SmarterMail!

Gabriel.

I have proposed this functionality many times. But SM has never said anything about it. The community didn't react much either.

I believe that those who have larger servers use an ouboung gateway and then make any routing rules from there.

On some domains I also do this even if in my case it's just a crazy trick.

Imagine that to use the routing rules, some rules on smtp outbound (content filter doesn't work on outbound in sm.. this is also crazy) I use one of my Icewarp servers as a gateway and then from there I make routing rules and outgoing filters.

I really don't understand why SM lacks these features.

Maybe SM has an explanation, but he never gave it to me

I'm desperate now so I just started emailing executives at Yahoo, sending them tweets and Linkedin messages. LOL 

Regarding feature suggestions, my experience has been that software vendors do what they want. On our Forum software, they have people vote for features on their forums, but who's got time to read that all the time and vote? LOL

This support page is a farse- https://senders.yahooinc.com/contact/

AT&T resolved right away though!

Did you sign up with Yahoo Feedback Loop with your NEW ip address? You had mentioned you've been doing it for years.

I have seen issues cleared just by signing up for these loops.

@Ron the Yahoo feedback loop does not work by IP address, it works by domain- https://senders.yahooinc.com/complaint-feedback-loop/

I tried to update it though a couple of days ago, it did not help. I will try to use the "add" option and see if that works.

I posted earlier an error regarding AT&T and Yahoo affiliation - but it's actually AOL that's affiliated - the AT&T/Yahoo was long ago.

Maybe blowing up AOL's postmaster loop will clear up Yahoo. Granted, Yahoo runs the infrastructure, but just maybe a needle in the haystack getting you unblocked.

AOL/Verizon Postmaster both lead to the Yahoo page. Yahoo totally controls it- https://help.aol.com/articles/aol-bulk-email-exception-list-allow-list

Yahoo should have been Microsoft, but they way too dumb. Credit, I've done a lot of dumb things in my life, but I never lost 45 billion dollars in one day.

Yahoo was early, but lacked leadership a cautionary tale for investors on A.I. Anyone remember the 199.00 express fee to get reviewed quickly for inclusion in the Yahoo directory?  They could reject your application with no refunds and did this several times to customers I designed websites for so you would have to appeal it.

Then they decided to charge 299 per year instead of 199 lifetime.

Customer service was lame.

Then came Google!

Update they unblocked us about 3 hours later! YEAH!

I've had two people email me this week about this topic saying that are blocked at Yahoo. I got an email from AWS a few weeks ago stating that in FEB 2024, Yahoo was going to start cracking down on bounces and spam complaints.

Make sure you are in the feedback complaint loop! We have clowns on our Ford Thunderbird Forum that will report valid forum messages as spam, so I started banning them last year. Glad I weeded them out.

The Feedback Loop increases your reputation with Yahoo!

How You weeded them out from Your database.. Now You have any block issue...
