the ip is not neccesarily in the mail.
the hostname is, which can be resolved to the ip-address.
you find this in the header section, shown if you choose plain text in your client or by reading the files with an editor in /var/mail.

how to suppress? very involved. the easy answer is: not possible.
the hard-answer is :
study up on sendmail. eg: www.sendmail.org
