SMTP 发送错误客户端无权向此服务器提交邮件。服务器响应为：4.7.1：拒绝中继访问

当我向我的域外（例如 Google、Microsoft 等）发送邮件时，我的服务器上会出现此错误。以下是我的 Postfix 配置文件。

# See /usr/share/postfix/main.cf.dist for a commented, more complete version
#postmap /etc/postfix/sasl_passwd

# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = no

# See http://www.postfix.org/COMPATIBILITY_README.html -- default to 3.6 on
# fresh installs.
compatibility_level = 3.6

#relayhost = [gritfy-com.mail.protection.outlook.com]:25
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128

答案1

使用邮件用户代理添加您发送邮件的网络地址，以便您的 postfix 接受来自用户的邮件

mynetworks = 127.0.0.0/8 your_network_here

或者在您的 MUA 中使用 SMTP 身份验证。也请检查这些。
