I have a mail server running postfix that sends a lot of emails and gets back a lot of bounces. These bounces a filling up my server and causing additional load.
if i know my book right, you send mail to a host that accept and bounce where thay should have rejected ?
in that case you should use dns rpz zone with a list of hosts that makes backscattering with accept and bounce
in postfix you can make a recipient access with hots to make local reject mail to hosts like this, sadly this is maintain works :(
Is there any way on a postfix level to reject/not accept any type of bounce that gets sent to the mail server?
if i am right above you should do nothing, if unsure show logs from you that shows exact problem
do not make -v on smtpd to be helpfull, raw plain logs not debug logs hopefully others can then help more then me
