通过 MS Office 365 发送时出现 Postfix 错误

我已经在 postfix 中配置了 Ms office 365。但在发送电子邮件时遇到错误。以下是日志。

AD0C147573: lost connection with smtp.office365.com[40.97.188.242] while sending RCPT TO

postconf -n 的输出

在 ubuntu 16 服务器中运行的 Postfix 也创建了 MX 和 TXT 记录。

编辑：Postfix 配置文件

smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache

我正在使用邮件发送电子邮件。

echo "Test Message" | mail -s "Test Subject" [email protected]

答案1

错误信息显示：

客户端未通过身份验证，无法在 MAIL FROM 期间发送匿名邮件

这意味着接收邮件主机（office365）不允许“邮件发件人”地址使用中继服务器。首先检查 SASL 用户名和密码是否正确。检查
smtp_sasl_password_maps = hash:/etc/postfix/sasl_password 中所述的其他要求

  • 用户名/电子邮件地址和密码 输入正在使用的托管邮箱的登录凭据
  • 验证：您必须能够配置用户名和密码才能在设备上发送电子邮件。
  • 邮箱：您必须拥有获得许可的 Office 365 邮箱才能发送电子邮件。

答案2

在 main.cf 中，您可能需要设置参数 smtp_pix_workarounds =

Pix 的解决方案之一是禁用 EHLO。

disable_esmtp 禁用所有扩展 SMTP 命令：发送 HELO 而不是 EHLO。

此功能在 Postfix 2.4 及更高版本中可用。默认设置向后兼容早期版本的 Postfix。
