My hosted email server is "Refusing to talk : 550" with my postfix server. Gmail, Yahoo, Hotmail all accepts them fine. All of sudden hosted email provider decided not accept email from my server. I dont really know why... i dont send out spam nor have large volumes.
Anyways, now they want me to get a bounce-back email. All the email in question are in mailq (deferred)
How do I expire them so that postfix will send out "unable to send" to mail clients who sent them?
I dont want to delete them...
Thanks for the help in advance
