In mine, it's a candidate for a rejection at SMTP time.

I now do nearly all of my spam filtering during the SMTP session.
There might once have been a reason to accept quickly and chew through
the mail later, but these days it all needs chewing so you might as
well do it right away.  This has the huge advantage that you can
reject unwanted mail after data with 550 FOAD rather than bouncing.
