Generally, this patch skips crucial security/safety features that
are difficult to enforce through a POSIX-on-Windows API. I see no
enforcement of uid/gid separation (permission checks are made in
the program itself instead of in the OS kernel, uid/gid numbers are
passed in an environment variable instead of being protected by the
OS kernel), weak or no enforcement of directory/file/socket
permissions, and no enforcement of file size limits.
Could I support this weakened version of Postfix? I would not put
my reputation on the line.
To run Postfix on Windows, I suggest using a VM with BSD or Linux,
or doing a proper port. The port would abstract out Postfix
security/safety features and provide different translation layers
for POSIX and Windows environments (instead of emulating a POSIX
subset on Windows)
