I tried:
maildir:
driver = appendfile
maildir_format = true
create_directory = false
directory = DIR_BOX/$domain/$local_part
mode = 0660
uid = -1
group = -1
Result:
2016-08-30 16:08:28 1beoNK-0003qs-PB unable to set gid=4294967295 or
uid=4294967295 (euid=0): local delivery to ednardo
<ednardo@???> transport=maildir
2016-08-30 16:08:28 1beoNK-0003qs-PB failed to read delivery status for
ednardo@??? from delivery subprocess
2016-08-30 16:08:29 1beoNK-0003qs-PB appendfile transport process

It seems exim keep trying modify uid and gid of the created file. Why?
