This particular client did bring up some Yahoo issues a week ago which I looked into it. The conclusion was Yahoo is deferring a small percentage of outbound mail for a small period of time due to mail volume. Overall we have great successful deliveries to Yahoo addresses on our Affinity server. So I am simply surprised at his communication sent to this list. Yahoo delivery always improves when mail volume becomes more consistent. That week we have moved over a moderate amount of lists that had a few dozen Yahoo members. That caused our SenderScore.org <http://senderscore.org/> rep score to drop from 98 to 96 (which is still a very high reputation). It's back up to 98 (pats myself on the back) because the new outgoing mail volume has become more consistent. Eventually we will fill up the server and will bring up a new server to add new lists to. This approach has worked well for all of our servers for years. So conclusion: broken DKIM signatures are not playing a part with his issues at all. At least from the evidence I have seen.
Also a client of harmony lists and assume to have have same server settings. I hear some Yahoo users have 100% email in spam. But no bounce related to yahoo. Maybe 10% of Yahoo users have problems. After marking them as not spam all users have reported that it is fixed and Yahoo doesn’t mark emails as spam. Yahoo spam detection obviously is a very personalized thing. Gmail overall is much better where < 1% of users see emails in spam. A good resource is here to understand what can be done. https://www.whitelist.guide/yahoo/
Unfortunately it’s not possible to debug such problems without having access to each subscribers email account. Subscribers without technical knowledge are very vague in their reports and do not always understand instructions how to fix it. My suspicion is that some users like to use the “report spam” buttons way too much and then end up with a extremely sensitive individual spam scoring.
