*) First of all, if you don't own domain name '@domain3.com', it's not recommended to do so, you're considered as spammer this way.
*) If you want to do so, please remove 'reject_sender_login_mismatch' in Postfix config file /etc/postfix/main.cf, it's a restriction rule in parameter 'smtpd_sender_restrictions'.
*) Configure your mail client (Outlook, Roundcube webmail, etc) to use 'do-not-reply@domain3.com' as 'From' address.
