Thanks Jeremy! At first, when I tried to run that command as root, it gave
some output ending with:

18:56:50 825 LOG: PANIC DIE
18:56:50 825 Cannot open main log file "/var/spool/exim/log/mainlog":
Permission denied: euid=0 egid=0
18:56:50 825 2024-05-09 18:56:50 Warning: purging the environment.
18:56:50 825 Suggested action: use keep_environment.

above

However, when I ran it inside "su - exim -s /bin/sh" (exim user:group is
exim:exim), I get the full following output:

Seems like when running as root, exim refuses to keep root permissions, but
when running as exim, it has insufficient privileges? I have the following
local_delivery section:

local_delivery:
driver = appendfile
file = /var/mail/$local_part_data
delivery_date_add
envelope_to_add
return_path_add
#group = exim
#mode = 0660

and I have the /var/mail directory set like so:

# ls -la /var/mail
total 0
drwxrwxrwt 1 exim exim 0 Apr 30 17:10 ./
drwxr-xr-x 1 root root 88 May 9 18:39 ../


Thanks for the help,
-Zacchae
