Javamail empty AUTH

Question

JavaMail SMTP를 통해 Exchange 서버 (버전 uknown)로 메일을 보냅니다. 내 로컬 시스템에서 테스트 할 때 정상적으로 작동합니다.

테스트 시스템에 소프트웨어를 배포하자마자 메일을 보내는 것이 더 이상 작동하지 않습니다.

테스트 시스템에서 소프트웨어를 사용할 때 빈 AUTH에주의하십시오. JavaMail에서 누락 된 항목은 무엇입니까?

Answer 1

mail.smtp.starttls.enable을 true로 설정하십시오.

또는 mail.smtp.ssl.enable을 true로 설정하십시오.

current version of JavaMail을 사용하고 있는지 확인하십시오.
