Discourse를 설치하고 계정 이메일을 활성화했는데, 왜 계속 계정 활성화 메일이 오는 건가요? 이 버그를 해결하려면 어떻게 설정해야 하나요?

Your authentication setup is correct, and the mail you’re receiving is the same job, over and over again.

Discourse gets through the whole mail sending process but after receiving an unknown response code it aborts, thinking the mail send failed.

But the mail server actually did accept the mail!

Since Discourse didn’t realise the send was actually successful, it reschedules the job over and over.
