That's procmail, not SA business.

Top posting is also discouraged.

Take your question and anywhere you mention SA substitute the name of 
another program. If the question is still reasonable and sensible, then 
the question isn't really about the program procmail is calling, it's 
about procmail.

To answer your question: yes. Procmail will pass a message through SA 
twice in that scenario. How would the program being called as a filter 
have any control over that?

To answer what I believe you're really asking, SA does nothing to attempt 
to detect whether a message has already been scanned and scored, as 
whatever test it used to detect that scanning would be subject to spoofing 
by spammers who wished to forge a low score on the message.

Basically if you're running SA at the global level you should tell your 
users to not run SA themselves.

Greetings, My apologies re: HTML encoding.  I've set Thunderbird to send 
this message plain-text-only; hopefully that will work.

I don't wish to become involved in a long debate, and get off topic, but 
how are methods of invoking SA are not SA business?  To me that seems 
like an integral part of using SA.  SA doesn't do much if it isn't invoked.

However, if that is the group policy, so be it.

Thanks,

P.S. My apologies to Matus UHLAR, who will probably receive this email 
twice.
