[TYPO3] Log IP Address from Form

[Sandy Matheson]

Hi,

We have had a number of unsavory emails generated by forms from one of
our websites and woudl like to display a message on the page with the
form giving the originators IP Address and stating that it will be
logged.  We would also like to include this IP address in the email
that is generated from the form.

Can anyone point me to how to do this?

Many thanks,

Sandy Matheson
