I noticed that spamassassin flags my form mail for "BUGGY_CGI".
I checked an old form mail (before 2.0) and they had the same thing. I added my domain to the whitelist to prevent my form mails from being tagged as spam.

But, I'm still wondering why they are flagged to begin with. I am using formmail.cgi version 1.92sn and the mails seem ok. I have very slightly modified the script, but nothing that seems to cause a bug.
Any idea what could be causing this?
