I have the same issue with work email (O365) going to Yahoo recipients.

 

I ran some tests from work email, my Gmail account, and my home email server (Alpine email client on *nix using sendmail), compared Yahoo's "view raw message" message headers, and found this is likely what is happening with each sending server:

 

O365 (mail goes to Spam)

   RCPT TO: "Joe Blow" <email address>

 

Alpine/Sendmail (mail goes to Inbox)

   RCPT TO: email address

 

Gmail (mail goes to Inbox)

   RCPT TO: email address

 

So specifically, if you look at the Yahoo raw message, it will show lines like this:

 

 

 

From O365:

Date: Fri, 3 Jun 2022 05:12:26 +0000
From: Amy Blow <amyblow7283[@]work-email-server.com>
To: "joe.blow[@]yahoo.com" <joe.blow[@]yahoo.com>
Subject: Test Message
From Alpine/Sendmail:

Date: Thu, 2 Jun 2022 23:30:27 -0400 (EDT)
From: Amy Blow <amyblow7283[@]home-email-server.com>
To: joe.blow[@]yahoo.com
Subject: Test Message
From Gmail:

Date: Fri, 3 Jun 2022 10:02:12 -0400
From: Amy Blow <amyblow7283[@]gmail.com>
To: joe.blow[@]yahoo.com
Subject: Test Message

    More information - I opened a case up with Yahoo (https://senders.yahooinc.com/contact), and sent them some sample headers of messages that were being dumped into the Spam folder.

     

    Here's what they had to say about it:

    I've reviewed your case and due to user complaints regarding unwanted email from your servers, some users may receive your mailings in their "Spam" folder. 

     

    Note they're not saying unwanted email from our domain, just from "your servers" which I take to mean Microsoft.

     

    The rest of the email was the same generic info everyone else received.

     

    So this may be a p!ssing contest between Yahoo and Microsoft, and we're all collateral damage. :sad:

      We have been able to use the glock tools free service to prove this is also happening with outlook.com and this is how we are getting our ticket with MS pushed forward. Had to create a new outlook.com account and get headers for them, but they cant blame outlook.com on yahoo so now they have to push the case forward instead of pointing fingers.
