Postfix:无法从远程客户端发送邮件

Postfix:无法从远程客户端发送邮件

我在从 postfix 发送邮件时遇到问题。我认为我的配置非常标准,最后它是根据各种指南整理而成的。我尝试从远程客户端(iOS Mail、Mac OS X Mail.app、Linux 上的 Thunderbird)发送邮件。从 iOS Mail 发送邮件正常,但 Mail.app 和 Thunderbird 不正常。我使用 SASL 身份验证(dovecot)和 TLS,配置如下,并附带日志消息。

错误:

Jan 05 12:27:41 svali postfix/smtpd[26448]: NOQUEUE: reject: RCPT from aaa.chello.sk[89.173.206.108]: 553 5.7.1 <xxx>: Sender address rejected: not owned by user xxx; from=<xxx> to=<yyy> proto=ESMTP helo=<[10.0.2.4]>

答案1

此错误

Sender address rejected: not owned by user xxx;

来自对提交端口的限制(master.cf 文件)

submission inet n       -       n       -       -       smtpd
  ...
  -o smtpd_sender_restrictions=reject_sender_login_mismatch
  ...

正如解释的那样man 5 postconf

拒绝发送者登录不匹配

拒绝请求$smtpd_sender_login_maps指定 MAIL FROM 地址的所有者,但客户端未(SASL)以该 MAIL FROM 地址所有者身份登录;或者当客户端(SASL)登录,但根据$smtpd_sender_login_maps

原因是iOS Mail 可以使用,但 Mail.app 和 Thunderbird 无法使用可能是您在配置邮件客户端时没有指定正确的发件人地址。
