# /usr/bin/doveconf userdb
userdb {
  args = /mnt/dovecot/userlist.passwd
  driver = passwd-file
}

You can use doveadm to see if a user exists (if dovecot will find it in

Well spotted, an UTF-8 character was in the file at the wrong place.  I had:
# doveadm user test00001
userdb lookup: user test00001 doesn't exist

And now:
# doveadm user test00001
userdb: test00001
  uid       : 1001
  gid       : 1001

# dovecot reload
#

I run the imaptest with user test00001, and I have the following lines in
/var/log/mail.log:
