Thanks for concerning my problem.
I am using the postfix mail server on linux server 9.1. My Problem is how to bounce back the email when the sender ( email@example.com
send to firstname.lastname@example.org
) which means that the yahooo.com is not existing in the internet server, how do i bounce back the email to the sender which could tell them the connection refused or sending failed. the email i want to bounce is in the queue there. so can it be done? or ihave to set the bounce time?
when i type mailq command, it comes out the message
This is the error message
1 kB connect to yahooo.com[18.104.22.168]: Connection refused
so if i want to set the one day to try sending email, if failed , the mail in the queue there should bounce to sender
Or you all need me to post the configuration to you. because i have run some others configuration.
