Hi Exim community!
I am having trouble delivering emails to local users via appendfile. I
can see the emails in /etc/spool/exim/inputs and read their contents
manually, but such mail is not delivered to the users. Specifically, it
seems such emails are defered and frozen. To debug this issue, I have
made the following changes to my (mostly default, except I added DKIM)
exim.conf (full exim.conf attached, domain redacted as my.domain):
I have enabled all logging:
log_selector = +all
I have also added a "message" field to any "require" fields in my ACLs
(since the messages are deferred and not rejected):
require message = Did not verify sender address
verify = sender
require message = relay not permitted
domains = +local_domains : +relay_to_domains
require message = Did not verify recipient
verify = recipient
None of the above messages are printed in the log. When I restart the
exim server, and try to send an email to myself from my gmail, I get the
following in my /var/spool/exim/log/mainlog (again, my domain replaced
with my.domain):

There is no error printed at this point. I then try to see the status
of that message by printing the contents of
/var/spool/exim/msglog/1s1rwf-00034B-0B:

*** Frozen
It seems to understand that postmaster@??? should translate to my
account at the current machine via /etc/aliases (zacchae@localhost), and
that the localuser transport of local_delivery should be used. However,
such delivery is deferred for some reason which is not printed to the
mainlog. My local_delivery config in the transports section is:
local_delivery:
driver = appendfile
file = /var/mail/$local_part_data
delivery_date_add
envelope_to_add
return_path_add
I thought maybe exim was unable to write the message to /var/mail/, so I
(temporarily) gave /var/mail 666 permissions, but this did not help. As
mentioned at the beginning, I can see the emails and their content in
/var/spool/exim/input.
Can you help me get mail to deliver to users?
