Hi http://www.postfix.org/header_checks.5.html
RULE: /X-Virus-Scanned/ REPLACE X-Virus-Scanned: Yes BEFORE: X-Virus-Scanned: clamav-milter 0.98.4 at testserver.rhsoft.net NOW: X-Virus-Scanned: Yes so far, so nice _____________________________________ but in case of "X-Spam-Status" i am out of ideas to get only the "version=3.4.0" away to not leak software versions and if possible the wrong "UNPARSEABLE_RELAY" and i am even not sure if it is possible at all the rest of the SpamAssasin header should stay untouched X-Spam-Status: No, score=0.0 required=5.0 tests=UNPARSEABLE_RELAY autolearn=ham autolearn_force=no version=3.4.0
