외부 사용자를 인증하려는 Dovecot

외부 사용자를 인증하려는 Dovecot

SQL 인증과 함께 dovecot 버전 2.3.4.1을 사용하고 있으며 완벽하게 작동합니다. 로그를 보면 PHP 스크립트를 사용하여 사용자 목록을 이메일로 보낼 때 비둘기장이 수신자를 인증하려고 시도하고 있는 것을 알 수 있습니다. 로그를 읽는 것이 틀렸을 수도 있지만 이메일이 다음에서 출발하는 경우[이메일 보호됨]에게[이메일 보호됨], 왜 비둘기장에서 인증을 시도할까요?[이메일 보호됨]? 다음은 로그의 관련 항목입니다.

어떤 아이디어가 있나요?

감사합니다
