Slow Delivery - Nothing in log
I am tracing some slow delivery of mail, about 20+ minutes

A message comes in, but Exim appears to make no delivery attempt for 20+
minutes.

The logs show the message is accepted, then 20 minutes later it is
delivered. Nothing in the logs during the 20 minutes for that message, no
delivery attempts.

When I look through the logs, the server is delivering other messages to
said domain/server.

What would cause Exim to just hold the message in the queue like that?

It happens for a small % of mail, and the delay is not always 20 minutes.

Anything I can check out in logs or configuration to determine why it is
holding up the delivery of the messages?

How often do you run the queue? Do you log the info that you
are running the queue?

main config option queue_only_load ? deliver_queue_load_max ?
queue_only_file ? smtp_accept_queue ?
smtp_accept_queue_per_connection ?

ACL control = queue_only ?
