Nabble says this:

I guess postfix calls Dovecot LDA as user 5000/5000 as per quoted
config above, right? **

That user has no access to the config in /etc/dovecot.

Do:

chmod a+x /etc/dovecot /etc/dovecot/conf.d
chmod a+r /etc/dovecot/*.conf* /etc/dovecot/conf.d/*.conf* /etc/dovecot/conf.d

** If you don't know, replace the call to the LDA in postfix with
a wrapper script:

===== BEGIN
#!/bin/bash

( date
   id
   echo "$@"
   original_LDA "$@"
   rc=$?
   echo rc=$rc
   exit $rc
) >>/tmp/lda.log 2>&1
=====END
If you don't have a test machine, better use
   >>/tmp/log/lda-$$.log 2>&1
in order to put all log files into one subdir of /tmp
and make sure their logging does not overlap.
