[유료] 발신 이메일 문제 해결 도움

[ambimorph]

“3865개의 이메일 작업이 실패했습니다. app.yml 파일을 확인하고 메일 서버 설정이 올바른지 점검하세요.”

At some point a few weeks ago email started failing. I haven’t had time to address it until now, and I’m at a bit of a loss. There was a similar problem here: Error: "There are 965 email jobs that failed. Check your app.yml and ensure that the mail server settings are correct." that was solved by rebooting the server. I tried rebooting the droplet, but that doesn’t seem to have helped. What else can I try?
