解决方法
I want to know that is it possible that using postfix or any other MTA,i can apply a restriction that email sender cannot change/spoof his sender email,and email is only sent from the email ID,through which it was authenticated.
是的,有可能.您可以使用smtpd_sender_login_maps和reject_authenticated_sender_login_mismatch
smtpd_sender_restrictions = permit_mynetworks,reject_authenticated_sender_login_mismatch,reject_unknown_sender_domain,reject_unlisted_sender,reject_unverified_sender smtpd_sender_login_maps = hash:/etc/postfix/sender_logins_maps /etc/postfix/sender_logins_maps user@example.net sasl_login_name1
