If it's largely certain types of spam you could try using some custom 
rules (either write them yourself, or search the web...there's lots of 
sites out there with additional SA rules) to catch the particular type of 
spam that's getting through.  If they're not using DNSBLs like the 
Spamhaus XBL, you could have SA do that (if it's not already) and tune the 
score for XBL hits way up.

As someone else mentioned, see if you have a recent version of SA.  Older 
versions (with their older rule sets) are going to miss spam that the 
latest would catch.  Spammers do adapt.
