Query: If a mail arrives [...]
This mailing list is used by SpamAssassin developers to discuss ongoing development work on SpamAssassin. Your question has nothing to do with that.
Your question is appropriate for the SpamAssassin users mailing list (see the SpamAssassin wiki article http://wiki.apache.org/spamassassin/MailingLists )
Be sure to search the list archives and the wiki for an answer before you post your question. You get an answer faster by finding it already posted than by asking it again, if the answer is already available.
