![Postfix 上的 Sieve Filter 有问题吗?](https://linux22.com/image/768870/Postfix%20%E4%B8%8A%E7%9A%84%20Sieve%20Filter%20%E6%9C%89%E9%97%AE%E9%A2%98%E5%90%97%EF%BC%9F.png)
我想知道是否有人可以解释一下我遇到的问题,目前我有一个简单的 postfix 服务器,前面有一个 PMG 网关。由于 PMG 网关有垃圾邮件过滤器,我需要将垃圾邮件重定向到用户的垃圾邮件文件夹。我已经完成了这个 zimbra,但在 postfix 上我觉得我遗漏了一些东西。这些是我采取的步骤
- 安装包并修改在 main.cf 底部添加以下内容
sudo apt-get install dovecot-sieve dovecot-managesieved
mailbox_command=/usr/lib/dovecot/deliver
然后编辑
/etc/dovecot/conf.d/90-sieve.conf
并添加此行来配置默认位置
sieve_default = /etc/dovecot/default.sieve
然后让 dovecot 用户读取文件
chgrp dovecot /etc/dovecot/conf.d/90-sieve.conf
进入 lda 插件并取消注释
/etc/dovecot/conf.d/15-lda.conf mail_plugins = sieve
创建文件筛选并编译
root@mail:/etc/dovecot# cat /etc/dovecot/default.sieve
require "fileinto";
#Filter email based on a subject
if header :contains "X-Spam-Flag" "YES" {
fileinto "Junk";
}
然后
cd /etc/dovecot
sievec default.sieve
并赋予 dovecot 权限
chgrp dovecot /etc/dovecot/default.svbin
- 重启 postfix 和 dovecot
我发送了一封测试垃圾邮件[电子邮件保护]
并且它将 xspam 标志标记为是,但它仍然进入收件箱而不是垃圾邮件文件夹
我检查了协议
root@mail:/etc/dovecot# doveconf | grep protocols
protocols = " imap sieve pop3"
ssl_protocols = !SSLv2 !SSLv3

答案1
检查 Dovecot 配置sieve_default=
以确认您已配置默认筛选脚本的预期路径。
# doveconf | grep sieve_default
sieve_default = /var/lib/dovecot/sieve/default.sieve
此外,筛选过滤器评估不会在所有操作上停止。将项目归档到多个文件夹中是完全有效的。如果您希望将邮件放在一个文件夹中,并且只放在该文件夹中,请在块stop
末尾添加一个命令{}
# cat /etc/dovecot/default.sieve
require "fileinto";
# filter email based on a header added by proxmox mail gateway
if header :contains "X-Spam-Flag" "YES" {
fileinto "Junk";
stop;
}
经过默认到达筛选脚本的末尾,执行隐式keep
动作stop
,这样即使没有明确说明,每个未结束的调用(在诸如的操作中)也将被保留。

非常感谢您的回复,我必须将默认位置更改为此,然后就可以了,谢谢
