I am successfully ported qmail-1.03 and it seems to work good.
I've replaced flock() with fcntl() such as somebody did from one japan site.
Problem with spooling (absent mkfifo() and UNIX named pipe implementation
under Cygwin) was resolved by turning to UNIX socket. The only one problem
that the first message is not triggered immediately after sending, but
with the next all OK.
And now in my ISP filials where Win2k lives qmail+vpopmail+mysql under
Win32 works.
Here is a only qmail patch.
I can send Win32 binaries
======cut======
Allow work under CYGWIN
