But SIEVE has to operate on the message data - there isn't enough information before the DATA command to run SIEVE, unless you extend SIEVE with tests for SMTP-Envelope data (e.g. a MAIL FROM test). Frankly any system-wide script like that is better left to the SMTP implentation's own filtering/ruleset behaviour.
