I see mails in the queue that are lying there for 8 hours and are not retried once or delivered at all. Even to local mailboxes. When I do a forced delivery with "exim -M" they are delivered immediately.

I still can't find any real explanation. When I do an "exim -Mvl" on those messages I see only something like this:
2023-12-05 06:01:27 Received from remote_local@remote_domain.tld H=somehost [xxx.xxx.xxx.xxx] P=esmtps X=TLS1.3:TLS_AES_256_GCM_SHA384:256 CV=no S=329774 id=re-pN3d2IHxfQNruApwij4_5FG3rcrMyBieEHng-5MZQ6Y6T-5MPVLBPK-PGD12PI@something
In the log I see for those messages: no immediate delivery: more than 10 messages received in one connection
But I would expect that a queue runner (I start exim with -q10m) in a future run would take these messages but it doesn't seem to happen.
This mail is from 3 hours ago. The only way currently I get those stuck mails out of my queues is to deliver them via "exiqgrep -if $regex|xargs exim -M" but then they usually get delivered immediately.
I have to say that I jumped from 4.94 to 4.97. So the problem might have started in a version in between. But I checked the changelogs and I can't find anything.
I could of course increase smtp_accept_queue_per_connection but to what? And that feels more like fighting a symptom and not the root cause.
With 4.94 and before I didn't run into this problem. What do I miss?
Best,
Niels
