我已经在 Linux 上使用 dovecot 配置了 postfix 邮件服务器。现在的问题是,当我配置自动回复时,它会向发件人回复两封邮件

我在 Linux 上配置了带有 dovecot 的 postfix 邮件服务器。现在的问题是,当我配置自动回复时,它会向发件人回复两封邮件。我使用 vacation.pl(postfix 管理员的 Perl 脚本)自动向发件人回复邮件。我之前已经配置过它,当时测试过没有问题。但在更改数据库结构后,我更改了 postfix 配置、dovecot 配置和 vacation.pl 脚本。我认为数据库查询没有问题。

当我向某个用户发送密件抄送时,我也遇到了同样的问题。该用户将收到两封邮件。我没有在 dovecot、autoreply 中找到问题出在哪里。

我的master.cf文件如下所示。

您可以通过筛选插件进行休假回复。它们还将添加强大的服务器端邮件过滤功能。

休假响应者的筛选文件示例:

require ["fileinto", "vacation"];

vacation
  # Reply at most once a day to a same sender
  :days 1
  :subject "Out of office reply"
  # List of additional recipient addresses which are included in the auto replying.
  # If a mail's recipient is not the envelope recipient and it's not on this list,
  # no vacation reply is sent for it.
  :addresses ["[email protected]", "[email protected]"]
"I'm out of office, please contact Joan Doe instead.
Best regards
John Doe";

我也遇到过内容过滤器的问题。在内容过滤器后添加此行可修复多条消息被发送的问题。

-o receive_override_options=no_address_mappings

在您的 smtp 声明中的所有过滤器之后添加该行,使其看起来像这样..

smtp      inet  n       -        -       -       -       smtpd 
#    -o content_filter=spamfilter:dummy
     -o content_filter=vacation:dummy
     -o content_filter=dfilt:dummy
     -o receive_override_options=no_address_mappings

但不可否认的是,我只用 spamassassin 过滤器测试过它。如果它有效,请告诉我。
