Problem of sending email

[Deleted user]

Hi,

I set up SMTP server in confluence.

(server host name : 127.0.0.1, port : 25)

I tried to send test mail.

and confluence show me success.

But It was failed and I checked SMTP log(/var/log/maillog).

there is error message(stat=User unknow)

How can I fix this problem?

Thank you

Hi 정민식,

This is more of Linux error saying that there is no mailbox for the user being sent the test email.
