Hi list,
I have been running this FC4 box with qmail for about 189 days. Recently
there is a kernel update and i decided to reboot the machine. And after
rebooting, i had error trying to send out emails. Below is the error.
An unknown error has occurred. Subject 'test', Account: 'testing', Server:
'mail.test.com', Protocol: SMTP, Server Response: '451 mail server
temporarily rejected message (#4.3.0)', Port: 25, Secure(SSL): No, Server
Error: 451, Error Number: 0x800CCC6A
Can anyone help me?
Thanks and best regards
