Message is Piped to a PHP script. CPANEL glitch preventing SA from Scanning before feeding to script.

[Don Ireland]

Is there a way to have my PHP Script feed a message to SA to be 
scanned?  I can save the message as a text file if that'll help.

I'm using a hosted (shared hosting plan) web account with CPanel 
access.  I've noticed that email messages that have been routed through 
my email forwarders are not being scanned by SA--there is no X-SPAM header.

I've asked my host about it and got this reply "It sometimes does not as 
it is an bug with cpanel".  So I'm looking for a way to get the message 
scanned by SA.  And after the message has been scanned, is there someway 
to let a PHP script know that SA is done with the message?

Thanks.
