hey everyone
i have three VPS machines , one is running sendmail service ,
i issued these command line on the second machine
Code:
echo "this is a test mail 1 " | mail -s 'test mail 1' -r user1@xxxx.com user1@xxxx.com
echo "this is a test mail 2 " | mail -s 'test mail 2' user1@xxxx.com
but mail client can accept test mail 2, and lost the To: and Subject: header of the test mail 1,
as you can see, test mail 1 is a spoofing mail
how can i set sendmail service to accept spoofing mails ?
