We get email from international students from Indonesia, China, Korea, etc. Sometimes the email trips one of the DATE_IN_FUTURE rules.
Does this happen because the sender's computer has bad date/time? Because of the time zone they are sending from? Or some other reason? Some of this email also ends up tripping one of the RCVD_IN_SORBS rules. Combined with another rule or two they end up classed as spam.
