It's probably too large (>500kB) and was thus given a free pass.  If
that is the case, you can alter spamass-milter to call spamc with a
higher max_size argument, like:

spamass-milter ... -- --max-size -s 1050000

as noted on the spamass-milter and spamc man pages.  (That's in bytes,
fudged just above 1MB since spammers like to just barely exceed the max
scan size threshold.)  You should pick something that correlates to
however much idle time is on your spam filtering server(s), e.g. if your
load average is typically near zero, go nuts (3MB should do for a very
large max size), but if you're already around one or higher, only bump
it slightly.

The default is either 500000 or 512000 bytes (the man page is ambiguous).
