This is could be the source of your problem, if your /usr/sbin/postdrop
doesn't have the permissions rwxr-sr-x you have a problem. The maildrop
directory needs to be either world writable or the postdrop program
needs to be have the setgid bit set. Also, normally maildrop has the
permissions drwx-wx--T. The T bit signifies that the last modified time
shouldn't be updated (chmod w+T /var/spool/postfix/maildrop).

http://www.postfix.org/security.html (see Set-uid).

Postfix may have been modified to stop working when the maildrop
directory is world writable, I can't remember.
