If its you or you are in a position to run your own MTA, your best bet is to let it pass incoming mail to Spamassassin and put the scored mail in the mailbox. This way your application can check for spam by looking at the X-Spam-Status header and you also have the opportunity of using the MTA's SMTP-time checks to apply blacklists etc and reject spam without needing to process it further. Configure the MTA to use spamc/spamd rather than calling the spamassassin script because its faster: where spamassassin goes through startup/shutdown for every message it scans, spamd only does so once, when the system is booted.
