By default, Exim will tell you why, with a log-line, when it doesn't
deliver immediately. This appears to have been turned off in your
installation -- I don't know if that's Debian or site-local.

This is the "delay_delivery" log selector field. See:
https://www.exim.org/exim-html-current/doc/html/spec_html/ch-log_files.html#SECTlogselector

If you run:

exim -bP log_selector

then you'll see the actual configured value.

Get the default logging of "why we're not delivering immediately" turned
back on, and you should be in a stronger position.

If it is turned on, then ... look for signs of a crashing Exim process
(eg, complaints in dmesg).
