Hi, Yesterday, I cced 5 patches to [email protected] using send-email, but all of them were rejected by mail server at vger.kernel.org as follows: "Dear [email protected], Your message to [email protected] was rejected by the recipient domain. The error that the other server returned was: " SMTP error, RCPT TO: 451 4.7.1 Hello [159.226.251.20], for recipient address <[email protected]> the policy analysis reported: zpostgrey: connect: Connection refused". Your original message is included as attachment." I have successfully posted to [email protected] previously. And maintainers have received my patch correctly yesterday. Do you know what is going on?
Many thanks
