我正在尝试使用 Oauth2 for Gmail 连接 SMTP,但遇到以下问题。
Oauth 令牌和电子邮件名称是正确的,并且可以连接 IMAP。
我正在遵循google 的示例。
DEBUG SMTP: Authenticate with SASL
DEBUG SMTP: SASL mechanisms allowed: XOAUTH2
DEBUG SMTP: SASL AUTH command trace suppressed
DEBUG SMTP SASL: Mechanisms: XOAUTH2
DEBUG SMTP SASL: No SASL support
DEBUG SMTP: SASL authentication failed
DEBUG SMTP: Attempt to authenticate
DEBUG SMTP: check mechanisms: LOGIN PLAIN DIGEST-MD5 NTLM
DEBUG SMTP: AUTH LOGIN command trace suppressed
