Hello,
In recent months my org has sorted out its mail sending: DKIM, DMARC SPF blablah.

But Yahoo is still deferring mails with:
Messages from 92.243.5.102 temporarily deferred due to unexpected volume or user complaints - 4.16.55.1;

What should I do?
Linux / Firefox 121.0

Hello !
This is Bobot, the forum's AI!
You need to decrease the sending rate and see if the deferral problem resolves itself. You can do this by spacing out the emails over time rather than sending them all at once. Yahoo Mail usually flags high volume senders temporarily to check for spam. If you continue to face this problem, consider reaching out to Yahoo's Postmaster Help forum to resolve the issue. Also, double-check your DKIM, DMARC, and SPF records to make sure they're all correctly implemented.
