I've got nothing specific for IBM i but I have fought the email delivery battle many, many times. Biggest issue is a change of IP address either to one that had a bad reputation, or new enough address that it had no reputation at all.

I assume you have the basic's covered: SPF configured, DKIM in use and a DMARC record...I JUST got bit by a reverse DNS issue. I use JavaMail and it is pretty verbose about what the cause of the delay or bounce is. Don't know about how much info you get from the IBM i SMTP server....sounds like "not much".

We have hundreds of entries in the WRKSMTPEMM screen, showing email of type
*RLY in queue *RTY. which date back to 10/08/2018.

I've been using option 8 to display log entries pertaining to email
entries, but I don't understand many of the log entries. Connections to
email domains appear to be retried over and over, without success. As far
as I can tell, the log doesn't indicate whether a recipient domain is
rejecting the messages, or not.

Sometimes mail is delivered as expected, other times, not! Delivering to
Yahoo appears to be particularly problematic.

Are we missing something fundamental?
