Leonardo,
I was the target of this last week and I feel your pain.
In implemneted reciever_verify and sender_verify & headers_sender_verify
options.
You should be able to add the reciever_verify if the domain that you
accept messages for is real as it will just check the existance of that
domain. Please check the docs or wait for someone to say I am wrong first.
Also "headers_check_syntax" may toss a few incorrectly formatted TO:'s ie:
"TO: all the world"
Dave,
