제목에서 알 수 있듯이 이메일(webmin + Thunderbird를 통해)만 보낼 수 있습니다.[이메일 보호됨]이메일을 사용하지만 다음과 같은 다른 도메인/계정을 사용합니다.[이메일 보호됨], 보내지 않습니다(webmin과 Thunderbird가 smtp 서버에 연결하고 성공했다고 말하더라도). 우선순위가 10인 MX 레코드를 설정했는데, 그것이 없으면 어쨌든 기본 주소를 사용하여 보낼 수 없습니다. 어떤 주소로든 받을 수 있지만 보낼 수는 없습니다. 어떻게 해야 합니까?
음, 정확한 구성이 무엇인지 모르므로 여기에 "자동 생성" 구성을 넣겠습니다(Github의 일부 프로그램을 사용했는데 더 이상 기억이 나지 않습니다).
