How to remove headers that reveal system information when sending mail in php

Question

I am using the mails () function of PHPs. I noticed that when viewing messages (which are sent) properties that are present in some headers that indicate

• name of the file that sent the email
• what version of php am i running
• information about my OS

I deleted the domain, but this is basically what is included. How can I stop this inclusion, or am I just paranoid about security? In addition, I would like to continue to use the phps mail function, and not configure anything else. Thank.
