I made the file "authinfo" located at: /etc/mail
Wat i inserted was:
AuthInfo:smtp.gmail.com "U:root" "I:youraccount@gmail.com" "P:yourpasshere", youraccount@gmail.com

We need to chown the "authinfo" file with:
chmod 0600 /etc/mail/authinfo
makemap hash /etc/mail/authinfo < /etc/mail/authinfo

Now we must copy the mc config file to the cf config file.
Open your terminal and type:
sendmailconfig or m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
You can also copy the file manualy but i like the sendmailconfig command

This is the working sendmail version and you can send to hotmail, yahoo or whatever mail accounts

I did not test the recieving with sendmail while my provider is blocking port 25.

There is only 1 problem left. If users are using the contact form, you will recieve a message from your own mail adres, but you can easy change that in the code
(by putting the emailadress form at the contact page into the body of the sended email)
If i done the coding part of it, i will let you all know.
