문제는 제가 받는 바운스 메일에 from 필드가 포함되어 있지 않아서, API 호출이 https://forum.example.com/admin/email/smtp_should_reject.json?from=&to=replies+verp-326f6e22828d2543ba65497a47608f13@mail.forum.example.com처럼 이루어질 때 다음 오류와 함께 400 상태 코드를 반환하기 때문인 것 같습니다:
{"errors":["param is missing or the value is empty or invalid: from"]}
mail-receiver 로그의 일부는 다음과 같습니다.

그러나, 올바른 from 주소(제 이메일을 넣는 경우)가 포함되어 있더라도 다음과 같은 응답이 돌아옵니다.
{"reject":true,"reason":"Mail to this address is not accepted. Check the address and try to send again?"}
