Take a look into the logfiles of sendmail (/var/log/mail?)
and grep for the sending address, that helps you to identify
the spam and the source. also grep your Webserver logfiles
for *mail* maybe a script is on your maschine (uploaded
by a user maybe?)

php is one possibility, another is cgi (perl etc.).
you can try to use filterrules on your box that block
mail from your webserver, but that makes you unable
to send mails via the webserver (maybe a webmailer etc.)
