AFAIK, non-priveledged user can do chown(2) with group=-1 (special value

represented as 65535 (not 65536!) on systems with 16-bit gid_t and
as 4294967295 on systems with 32-bit gid_t. On Linux, for example,
uid_t and gid_t are 32-bit integers. Try those values.
Does Exim accept "group = -1" in driver definition? I did not check.
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
<[email protected]> transport=maildir
2016-08-30 16:08:28 1beoNK-0003qs-PB failed to read delivery status for

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?
