smtp_tls_security_level = may smtp_tls_note_starttls_offer = yes smtpd_tls_received_header = yes 如果您希望强制使用TLS加密,请将smtp_tls_security_level和smtpd_tls_security_level设置为encrypt。 配置SMTP认证为了安全起见,建议启用SMTP认证。以下是一个使用Postfix作为邮件传输代理并启用SMTP认证的示例配置:...
POSTFIX_smtp_tls_security_level = Relay host TLS connection level XOAUTH2_CLIENT_ID = OAuth2 client id used when configured as a relayhost. XOAUTH2_SECRET = OAuth2 secret used when configured as a relayhost. XOAUTH2_INITIAL_ACCESS_TOKEN = Initial OAuth2 access token. XOAUTH2_INITIAL_REF...
smtp_tls_security_level (empty) The default SMTP TLS security level for the Postfix SMTP client; when a non-empty value is specified, this overrides the obsolete parameters smtp_use_tls, smtp_enforce_tls, and smtp_tls_enforce_peername. smtp_sasl_tls_security_options ($smtp_sasl_security_...
