File deletion requires write permission on the directory the file is in,
not the file itself - because what you are really doing is removing the
file's entry in the directory. This is a UNIX permission "feature",
nothing to do with Samba.

However, (under Linux at least) if you set the "sticky" bit (chmod +t or
something like chmod 1777) on the directory, then only a file's owner can
delete/rename files - which is why most distributions set the sticky bit
on /tmp and /var/mail
