AFAIK, non-priveledged user can do chown(2) with group=-1 (special value
meaning file group should not be altered). However, the value -1 is
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.
