问题 My code checks a mailbox, and forwards every mail to another user. But I found out that the same contents are decoded differently according to mail clients(I mean, when sent with account@gmail.com, with account@naver.com, and etc). For example: what I typed, subject: subject content: this is content for mail client 1: 358 2020-04-22 18:12:23,249: run: DEBUG: subject has come as: =?utf-8?B?c3ViamVjdA==?= 359 2020-04-22 18:12:23,249: run: DEBUG: content has come as: dGhpcyBpcyBjb250ZW50Cg== for
