Some emails don't get forwarded, some do

You can't get that info from the Delivery tracker either unfortunately. That status can change too for example sometimes the code yahoo sends back is C="250 ok dirdel meaning direct delivery (no queue) but @sparek-3 is correct you can at least find the server that is accepting the message and pending the logs haven't been rotated there shouldn't really be an issue with identifying the mail, especially if you have the Message-ID they queued it as.

Thanks a lot for all your replies and explanations. I replied to Yahoo Postmaster and sent him that original log and asked if he can trace with that ID from the log. I'll let you know what he says.

Where did you get the log entry:

2019-05-21 13:57:25 1hT3OW-0007ZW-Or => mail.example(at)yahoo.com (mail.example(at)example.com) <mail.example(at)example.com> SRS=<SRS0=6D/mzn=TV=posta.omisli.si=bounce-md_76337.3e77a.v1-207bcd1662f332a05f542174895(at)barbaramilavec.com> R=lookuphost T=remote_smtp H=mta7.am0.yahoodns.net [98.136.102.54] X=TLSv1.2:ECDH-RA-AE25-GCM-HA34:25 CV=no C="25 2.0.0 Ok: queued as 78F140E1"
2019-05-21 13:57:25 1hT3OW-0007ZW-Or Completed

As said in my last post, my hosting provider sent it to me by email. I told them about my problem so they sent this log as an example of the log showing the email has been forwarded successfully. Then when I asked if they could send me more of them (so that I could send them to Yahoo), they said I can check them myself in cPanel Track Delivery section and I realised only later it's not the same kind of log. I'll ask them to send me more logs if necessary but I'll wait for the response from Yahoo first.

HI @BarbM

Great, I'm glad to hear that you got them the transaction though. I hope that they will have logs this far back and that some progress is made on this for you!

This is an older post, but I found it through a google search when I was trying to use the forwarding feature on cPanel.
Gmail received the forwarded emails fine but Yahoo did not.

Through troubleshooting the issue I found that Yahoo worked after I setup SPF, DMARC, and DKIM on my domain name. cPanel allows this easily by going to "Email Deliverability" then letting it add your SPF and DKIM records (copy/paste the info to your domain provider if you're not using cPanel for managing DNS records).
Then if you go to your Zone Editor and click Manage next to your domain, then add a DMARC record.
It took about 10 minutes to filter through before yahoo started receiving the forwards for me.

Whether that's a permanent solution or not is to be seen, but doing those steps definitely worked when deliverability failed.
Just thought I'd share in case anyone else stumbled on this forum post and hadn't added SPF, DMARC, and DKIM yet.

There could be a variety of reasons why some emails do not get forwarded while others do. One possibility is that the email service or client you are using has certain settings or filters in place that prevent certain emails from being forwarded. Another possibility is that the sender of the email has included specific instructions or code that prevent the email from being forwarded. Additionally, some email providers or clients may have built-in security features that prevent emails from being forwarded to protect the sender's privacy.
