我使用Sieve设置了带有Spamassassin和Dovecot的Postfix。 Spamassassin会将电子邮件标记为垃圾邮件。
我正在尝试让Sieve将SpamAssassin标记为“Spam”的邮件移动到Junk文件夹中。但是，它没有这样做。我不知道我做错了什么而且非常沮丧。
这是我的dovecot.conf转储：

我的/etc/dovecot/sieve/sieve.default如下：
$ cat /etc/dovecot/sieve/sieve.default
require "fileinto";
if header :contains "X-Spam-Flag" "YES" {
fileinto "Junk";
}
存在“Junk”文件夹。这是电子邮件的转储：

我正在测试从一台服务器到另一台服务器的此电子邮件，发件人和收件人不是同一台机器。收件人是user@testmail.domain.tld，发件人是user@domain.tld。该电子邮件明确标记为垃圾邮件。
为什么不将电子邮件移动到垃圾文件夹？
答案 0 :(得分：3)
想出来。由于我仍然是一个菜鸟，我的回答可能不是最好的，但我希望它可以帮助那些人。
这有一些问题，但主要是postfix没有将邮件路由到dovecot进行传递。 Dovecot +筛子被完全绕过。
要解决这个问题，我必须让Postfix和Dovecot通过lmtp进行通信。首先，我设置了dovecot：
protocol lda {
mail_plugins = $mail_plugins sieve
}
protocol lmtp {
mail_plugins = $mail_plugins sieve
}
service lmtp {
inet_listener lmtp {
address = 127.0.0.1 ::1
port = 10025
}
}
然后我不得不告诉postfix与dovecot交谈。我这样做了：
virtual_transport = lmtp:[::1]:10025
然后回到dovecot，我必须正确配置筛子。
plugin {
sieve = ~/.dovecot.sieve
sieve_dir = ~/sieve
sieve_before = /etc/dovecot/sieve/sieve.default
sieve_default = /etc/dovecot/sieve/sieve.default
sieve_global_dir = /var/lib/dovecot/sieve/
}
service managesieve-login {
inet_listener sieve {
port = 4190
}
service_count = 1
process_min_avail = 0
vsz_limit = 64M
}
service managesieve {
process_limit = 1024
}
protocol sieve {
managesieve_max_line_length = 65536
mail_max_userip_connections = 10
# Space separated list of plugins to load (none known to be useful so far).
# Do NOT try to load IMAP plugins here.
mail_plugins =
managesieve_logout_format = bytes=%i/%o
managesieve_implementation_string = Dovecot Pigeonhole
managesieve_sieve_capability =
managesieve_notify_capability =
managesieve_max_compile_errors = 5
}
从这里开始，我在/etc/dovecot/sieve/sieve.default中加入了标准的spamassassin过滤规则，在我的案例中是：
require "fileinto";
if header :contains "X-Spam-Flag" "YES" {
fileinto "Junk";
}
之后，我跑了：
sievec /etc/dovecot/sieve/sieve.default
这“编制”了筛选规则。最后，我重新启动了dovecot和postfix。
sudo service dovecot restart
sudo service postfix restart
在那之后，我给自己发了一个测试垃圾邮件，它被重定向到垃圾邮件文件夹。我希望这有所帮助，我要求你原谅并纠正我可能犯过的任何错误。
