The problem is that my spamming come frequently from known source
but with content not desired at that time. Hmm not really clear hey!
Example, you may receive a letter from a mailing list without a valid To
field but 2 days later you may receive a 10K order from the same domain.
You see? 

Anyway thanks for your input.
