筛选重定向到外国电子邮件时出现“中继访问被拒绝”

我有一个带有 sql 身份验证的 postfix 邮件服务器，我想在其上实现筛选。

Sieve 运行良好，包含“fileinto”的规则执行完美。我在 Sieve 中配置了一条规则，将任何包含“redirect”主题的电子邮件重定向到指定的外部目的地。因此实际上来自[电子邮件保护]对于本地用户[电子邮件保护]应重定向至[电子邮件保护]当主题包含“重定向”时

if header :contains ["subject"] ["redirect"]  {redirect "[email protected]"; stop;}

当我测试它时，我得到以下日志条目

postfix/smtpd[32114]: NOQUEUE: reject: RCPT from mail.server.net[xx.xx.xx.xx]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail.server.net>

我如何告诉 postfix 让 dovecot/sieve 中继电子邮件？

有人可以提示一下吗？

答案1

我不确定 Pigeonhole 是否实现了客户端 SMTP AUTH，但我没有找到相关设置。另一方面，您可以使用 sendmail 脚本代替 SMTP 来规避该限制。

看：

# Binary to use for sending mails.
#sendmail_path = /usr/sbin/sendmail

# If non-empty, send mails via this SMTP host[:port] instead of sendmail.
submission_host = localhost

还有一种叫 SRS 的东西发件人重写方案，这将通过添加和删除一些标题来将普通电子邮件转换为信封电子邮件。还有一个RFC 5293指定筛选命令“addheader”和“deleteheader”允许更改电子邮件，但 Pigeonhole Sieve 似乎尚不支持它。
