You may  want to check the sites you are hosting and make certain that
anyone running a formmail script is using a "secure" formmail script. Its
very common to see these script being abused.

Just a side note you may want to test your SMTP server using a tool such as
the SMTP utility available at zoneedit: http://www.zoneedit.com/smtp.html
You can be certain of what sendmail will pass through using this utility.
Responses from your server are printed for you.
