Modify sender domain address in Postfix

@Michael_Dahlgren_Nie Probably I’ve found what do you need. You have to modify the file /etc/postfix/canonical by adding at the end of the file this line: user@yourdomain.ext user@ispdomain.ext Replace user and yourdomain/ispdomain with real values. Then launch command postmap /etc/postfix/canonical and check that it doesn’t return errors. If yes restart postfix with systemctl restart postfix I don’t know if you can send emails with ISP domain without finish in SPAM: you can try. Remember …

Please have a look to this post. I think it can be a solution.
